Liberalism is a political and moral philosophy based on the rights of the individual, liberty, consent of the governed, political equality, right to private property, and equality before the law. Different liberals espouse various and sometimes conflicting views depending on their understanding of these principles but generally support liberal democracy, private property, market economies, individual rights (including civil rights and human rights), secularism, rule of law, economic and political freedom, freedom of speech, freedom of the press, freedom of assembly, and freedom of religion. Liberalism is frequently cited as a major ideology of modern history.
Liberalism became a distinct movement in the Age of Enlightenment, gaining popularity among Western philosophers and economists. Liberalism sought to replace the norms of hereditary privilege, state religion, absolute monarchy, the divine right of kings, and traditional conservatism with representative democracy, rule of law, and equality under the law. Liberals also ended mercantilist policies, royal monopolies, and other trade barriers, instead promoting free trade and marketization. The philosopher John Locke is often credited with founding liberalism as a distinct tradition based on the social contract, arguing that each man has a natural right to life, liberty and property, and governments must not violate these rights. While the British liberal tradition emphasized expanding democracy, French liberalism emphasized rejecting authoritarianism.
Leaders in the British Glorious Revolution of 1688, the American Revolution of 1776, and the French Revolution of 1789 used liberal philosophy to justify the armed overthrow of royal sovereignty. The 19th century saw liberal governments established in Europe and South America, and it was well-established alongside republicanism in the United States. In Victorian Britain, it was used to critique the political establishment, appealing to science and reason on behalf of the people.
During the 19th and early 20th centuries, liberalism in the Ottoman Empire and the Middle East influenced periods of reform, such as the Tanzimat and Al-Nahda, and the rise of constitutionalism, nationalism, and secularism. These changes, along with other factors, helped to create a sense of crisis within Islam, which continues to this day, leading to Islamic revivalism.
Before 1920, the main ideological opponents of liberalism were communism, conservatism, and socialism; liberalism then faced major ideological challenges from fascism and Marxism–Leninism. During the 20th century, liberal ideas spread further, especially in Western Europe, as liberal democracies were among the victors in both world wars and the Cold War.
Liberals sought and established a constitutional order that prized important individual freedoms, such as freedom of speech and freedom of association; an independent judiciary and public trial by jury; and the abolition of aristocratic privileges. Later waves of modern liberal thought and struggle were strongly influenced by the need to expand civil rights. Liberals have advocated gender and racial equality in their drive to promote civil rights, and global civil rights movements in the 20th century achieved several objectives towards both goals. Other goals often accepted by liberals include universal suffrage and universal access to education. In Europe and North America, the establishment of social liberalism (often called simply liberalism in the United States) became a key component in expanding the welfare state.
21st-century liberal parties continue to wield power and influence throughout the world. The fundamental elements of contemporary society have liberal roots. The early waves of liberalism popularised economic individualism while expanding constitutional government and parliamentary authority.

Origins
Liberal, liberty, libertarian, and libertine all trace their etymology to liber, a root from Latin that means "free". One of the first recorded instances of liberal occurred in 1375 when it was used to describe the liberal arts in the context of an education desirable for a free-born man. The word's early connection with the classical education of a medieval university soon gave way to a proliferation of different denotations and connotations. Liberal could refer to "free in bestowing" as early as 1387, "made without stint" in 1433, "freely permitted" in 1530, and "free from restraint"—often as a pejorative remark—in the 16th and the 17th centuries.
In the 16th-century Kingdom of England, liberal could have positive or negative attributes in referring to someone's generosity or indiscretion. In Much Ado About Nothing, William Shakespeare wrote of "a liberal villaine" who "hath ... confest his vile encounters". With the rise of the Enlightenment, the word acquired decisively more positive undertones, defined as "free from narrow prejudice" in 1781 and "free from bigotry" in 1823. In 1815, the first use of liberalism appeared in English. In Spain, the liberales, the first group to use the liberal label in a political context, fought for decades to implement the Spanish Constitution of 1812. From 1820 to 1823, during the Trienio Liberal, King Ferdinand VII was compelled by the liberales to swear to uphold the 1812 Constitution. By the middle of the 19th century, liberal was used as a politicised term for parties and movements worldwide.
Yellow is the political colour most commonly associated with liberalism. The United States differs from other countries in that conservatism is associated with red and liberalism with blue.
Modern usage and definitions
In Europe and Latin America, liberalism means a moderate form of classical liberalism and includes both conservative liberalism (centre-right liberalism) and social liberalism (centre-left liberalism). In North America, liberalism almost exclusively refers to social liberalism. The dominant Canadian party is the Liberal Party, and the Democratic Party is usually considered liberal in the United States. In the United States, conservative liberals are usually called conservatives in a broad sense.
Over time, the meaning of liberalism began to diverge in different parts of the world. Since the 1930s, liberalism is usually used without a qualifier in the United States, to refer to social liberalism, a variety of liberalism that endorses a regulated market economy and the expansion of civil and political rights, with the common good considered as compatible with or superior to the freedom of the individual.
According to the Encyclopædia Britannica, "In the United States, liberalism is associated with the welfare-state policies of the New Deal programme of the Democratic administration of Pres. Franklin D. Roosevelt, whereas in Europe it is more commonly associated with a commitment to limited government and laissez-faire economic policies." This variety of liberalism is also known as modern liberalism to distinguish it from classical liberalism, which in the United States evolved into modern conservatism. These two forms of liberalism comprise the two main poles of American politics, in the forms of modern American liberalism and modern American conservatism.
Some liberals, who call themselves classical liberals, fiscal conservatives, or libertarians, endorse fundamental liberal ideals but diverge from modern liberal thought on the grounds that economic freedom is more important than social equality. Consequently, the ideas of individualism and laissez-faire economics previously associated with classical liberalism are key components of modern American conservatism and movement conservatism, and became the basis for the emerging school of modern American libertarian thought. In this American context, liberal is often used as a pejorative.
This political philosophy is exemplified by enactment of major social legislation and welfare programs. Two major examples in the United States are Franklin D. Roosevelt's New Deal policies and later Lyndon B. Johnson's Great Society, as well as other accomplishments such as the Works Progress Administration and the Social Security Act in 1935, as well as the Civil Rights Act of 1964 and the Voting Rights Act of 1965. Modern liberalism, in the United States and other major Western countries, now includes issues such as same-sex marriage, transgender rights, the abolition of capital punishment, reproductive rights and other women's rights, voting rights for all adult citizens, civil rights, environmental justice, and government protection of the right to an adequate standard of living. National social services, such as equal educational opportunities, access to health care, and transportation infrastructure are intended to meet the responsibility to promote the general welfare of all citizens as established by the United States Constitution.
Philosophy
Liberalism—both as a political current and an intellectual tradition—is mostly a modern phenomenon that started in the 17th century, although some liberal philosophical ideas had precursors in classical antiquity and Imperial China. The Roman Emperor Marcus Aurelius praised "the idea of a polity administered with regard to equal rights and equal freedom of speech, and the idea of a kingly government which respects most of all the freedom of the governed". Scholars have also recognised many principles familiar to contemporary liberals in the works of several Sophists and the Funeral Oration by Pericles. Liberal philosophy is the culmination of an extensive intellectual tradition that has examined and popularized some of the modern world's most important and controversial principles. Its immense scholarly output has been characterized as containing "richness and diversity", but that diversity often has meant that liberalism comes in different formulations and presents a challenge to anyone looking for a clear definition.
Major themes
Although all liberal doctrines possess a common heritage, scholars frequently assume that those doctrines contain "separate and often contradictory streams of thought". The objectives of liberal theorists and philosophers have differed across various times, cultures and continents. The diversity of liberalism can be gleaned from the numerous qualifiers that liberal thinkers and movements have attached to the term "liberalism", including classical, egalitarian, economic, social, the welfare state, ethical, humanist, deontological, perfectionist, democratic, and institutional, to name a few. Despite these variations, liberal thought does exhibit a few definite and fundamental conceptions.
Political philosopher John Gray identified the common strands in liberal thought as individualist, egalitarian, meliorist and universalist. The individualist element avers the ethical primacy of the human being against the pressures of social collectivism; the egalitarian element assigns the same moral worth and status to all individuals; the meliorist element asserts that successive generations can improve their sociopolitical arrangements, and the universalist element affirms the moral unity of the human species and marginalises local cultural differences. The meliorist element has been the subject of much controversy, defended by thinkers such as Immanuel Kant, who believed in human progress, while suffering criticism by thinkers such as Jean-Jacques Rousseau, who instead believed that human attempts to improve themselves through social cooperation would fail.
The liberal philosophical tradition has searched for validation and justification through several intellectual projects. The moral and political suppositions of liberalism have been based on traditions such as natural rights and utilitarian theory, although sometimes liberals even request support from scientific and religious circles. Through all these strands and traditions, scholars have identified the following major common facets of liberal thought:
believing in equality and individual liberty
supporting private property and individual rights
supporting the idea of limited constitutional government
recognising the importance of related values such as pluralism, toleration, autonomy, bodily integrity, and consent
Classical and modern
Enlightenment philosophers are given credit for shaping liberal ideas. These ideas were first drawn together and systematized as a distinct ideology by the English philosopher John Locke, generally regarded as the father of modern liberalism. Thomas Hobbes attempted to determine the purpose and the justification of governing authority in post-civil war England. Employing the idea of a state of nature — a hypothetical war-like scenario prior to the state — he constructed the idea of a social contract that individuals enter into to guarantee their security and, in so doing, form the State, concluding that only an absolute sovereign would be fully able to sustain such security. Hobbes had developed the concept of the social contract, according to which individuals in the anarchic and brutal state of nature came together and voluntarily ceded some of their rights to an established state authority, which would create laws to regulate social interactions to mitigate or mediate conflicts and enforce justice. Whereas Hobbes advocated a strong monarchical commonwealth (the Leviathan), Locke developed the then-radical notion that government acquires consent from the governed, which has to be constantly present for the government to remain legitimate. While adopting Hobbes's idea of a state of nature and social contract, Locke nevertheless argued that when the monarch becomes a tyrant, it violates the social contract, which protects life, liberty and property as a natural right. He concluded that the people have a right to overthrow a tyrant. By placing the security of life, liberty and property as the supreme value of law and authority, Locke formulated the basis of liberalism based on social contract theory. To these early enlightenment thinkers, securing the essential amenities of life—liberty and private property—required forming a "sovereign" authority with universal jurisdiction.
His influential Two Treatises (1690), the foundational text of liberal ideology, outlined his major ideas. Once humans moved out of their natural state and formed societies, Locke argued, "that which begins and actually constitutes any political society is nothing but the consent of any number of freemen capable of a majority to unite and incorporate into such a society. And this is that, and that only, which did or could give beginning to any lawful government in the world". The stringent insistence that lawful government did not have a supernatural basis was a sharp break with the dominant theories of governance, which advocated the divine right of kings and echoed the earlier thought of Aristotle. Dr John Zvesper described this new thinking: "In the liberal understanding, there are no citizens within the regime who can claim to rule by natural or supernatural right, without the consent of the governed".
Liberal economic theory
Adam Smith's The Wealth of Nations, published in 1776, followed by the French liberal economist Jean-Baptiste Say's treatise on Political Economy published in 1803 and expanded in 1830 with practical applications, were to provide most of the ideas of economics until the publication of John Stuart Mill's Principles in 1848. Smith addressed the motivation for economic activity, the causes of prices and wealth distribution, and the policies the state should follow to maximise wealth.
Smith wrote that as long as supply, demand, prices and competition were left free of government regulation, the pursuit of material self-interest, rather than altruism, maximises society's wealth through profit-driven production of goods and services. An "invisible hand" directed individuals and firms to work toward the nation's good as an unintended consequence of efforts to maximise their gain. This provided a moral justification for accumulating wealth, which some had previously viewed as sinful.
Smith assumed that workers could be paid as low as was necessary for their survival, which David Ricardo and Thomas Robert Malthus later transformed into the "iron law of wages". His main emphasis was on the benefit of free internal and international trade, which he thought could increase wealth through specialisation in production. He also opposed restrictive trade preferences, state grants of monopolies and employers' organisations and trade unions.
While Smith advocated for minimal government intervention, he recognized that some market regulation was necessary to prevent fraud, protect consumers, and ensure fair competition.
Other than that government should be limited to defence, public works and the administration of justice, financed by taxes based on income. Smith was one of the progenitors of the idea, which was long central to classical liberalism and has resurfaced in the globalisation literature of the later 20th and early 21st centuries, that free trade promotes peace. Smith's economics was carried into practice in the 19th century with the lowering of tariffs in the 1820s, the repeal of the Poor Relief Act that had restricted the mobility of labour in 1834 and the end of the rule of the East India Company over India in 1858.
In his Treatise (Traité d'économie politique), Say states that any production process requires effort, knowledge and the "application" of the entrepreneur. He sees entrepreneurs as intermediaries in the production process who combine productive factors such as land, capital and labour to meet the consumers' demands. As a result, they play a central role in the economy through their coordinating function. He also highlights qualities essential for successful entrepreneurship and focuses on judgement, in that they have continued to assess market needs and the means to meet them. This requires an "unerring market sense". Say views entrepreneurial income primarily as the high revenue paid in compensation for their skills and expert knowledge. He does so by contrasting the enterprise and supply-of-capital functions, distinguishing the entrepreneur's earnings on the one hand and the remuneration of capital on the other. This differentiates his theory from that of Joseph Schumpeter, who describes entrepreneurial rent as short-term profits which compensate for high risk (Schumpeterian rent). Say himself also refers to risk and uncertainty along with innovation without analysing them in detail.
Liberal feminist theory
Liberal feminism, the dominant tradition in feminist history, is an individualistic form of feminist theory that focuses on women's ability to maintain their equality through their actions and choices. Liberal feminists hope to eradicate all barriers to gender equality, claiming that the continued existence of such barriers eviscerates the individual rights and freedoms ostensibly guaranteed by a liberal social order. They argue that society believes women are naturally less intellectually and physically capable than men; thus, it tends to discriminate against women in the academy, the forum and the marketplace. Liberal feminists believe that "female subordination is rooted in a set of customary and legal constraints that blocks women's entrance to and success in the so-called public world". They strive for sexual equality via political and legal reform.
British philosopher Mary Wollstonecraft (1759–1797) is widely regarded as the pioneer of liberal feminism, with A Vindication of the Rights of Woman (1792) expanding the boundaries of liberalism to include women in the political structure of liberal society. In her writings, such as A Vindication of the Rights of Woman, Wollstonecraft commented on society's view of women and encouraged women to use their voices in making decisions separate from those previously made for them. Wollstonecraft "denied that women are, by nature, more pleasure seeking and pleasure giving than men. She reasoned that if they were confined to the same cages that trap women, men would develop the same flawed characters. What Wollstonecraft most wanted for women was personhood".
John Stuart Mill was also an early proponent of feminism. In his article The Subjection of Women (1861, published 1869), Mill attempted to prove that the legal subjugation of women is wrong and that it should give way to perfect equality. He believed that both sexes should have equal rights under the law and that "until conditions of equality exist, no one can possibly assess the natural differences between women and men, distorted as they have been. What is natural to the two sexes can only be found out by allowing both to develop and use their faculties freely". Mill frequently spoke of this imbalance and wondered if women were able to feel the same "genuine unselfishness" that men did in providing for their families. This unselfishness Mill advocated is the one "that motivates people to take into account the good of society as well as the good of the individual person or small family unit". Like Mary Wollstonecraft, Mill compared sexual inequality to slavery, arguing that their husbands are often just as abusive as masters and that a human being controls nearly every aspect of life for another human being. In his book The Subjection of Women, Mill argues that three major parts of women's lives are hindering them: society and gender construction, education and marriage.
Social liberal theory
Jean Charles Léonard Simonde de Sismondi's New Principles of Political Economy (French: Nouveaux principes d'économie politique, ou de la richesse dans ses rapports avec la population) (1819) represents the first comprehensive liberal critique of early capitalism and laissez-faire economics, and his writings, which were studied by John Stuart Mill and Karl Marx among many others, had a profound influence on both liberal and socialist responses to the failures and contradictions of industrial society. By the end of the 19th century, the principles of classical liberalism were being increasingly challenged by downturns in economic growth, a growing perception of the evils of poverty, unemployment and relative deprivation present within modern industrial cities, as well as the agitation of organised labour. The ideal of the self-made individual who could make his or her place in the world through hard work and talent seemed increasingly implausible. A major political reaction against the changes introduced by industrialisation and laissez-faire capitalism came from conservatives concerned about social balance, although socialism later became a more important force for change and reform. Some Victorian writers, including Charles Dickens, Thomas Carlyle and Matthew Arnold, became early influential critics of social injustice.
New liberals began to adapt the old language of liberalism to confront these difficult circumstances, which they believed could only be resolved through a broader and more interventionist conception of the state. An equal right to liberty could not be established merely by ensuring that individuals did not physically interfere with each other or by having impartially formulated and applied laws. More positive and proactive measures were required to ensure that every individual would have an equal opportunity for success.
John Stuart Mill contributed enormously to liberal thought by combining elements of classical liberalism with what eventually became known as the new liberalism. Mill's 1859 On Liberty addressed the nature and limits of the power that can be legitimately exercised by society over the individual. He gave an impassioned defence of free speech, arguing that free discourse is a necessary condition for intellectual and social progress. Mill defined "social liberty" as protection from "the tyranny of political rulers". He introduced many different concepts of the form tyranny can take, referred to as social tyranny and tyranny of the majority. Social liberty meant limits on the ruler's power through obtaining recognition of political liberties or rights and establishing a system of "constitutional checks".
Anti-state liberal theory
Classical liberalism advocates free trade under the rule of law. In contrast, the "anti-state liberal tradition", as described by Ralph Raico, was supportive of a system where law enforcement and the courts being provided by private companies, minimizing or rejecting the role of the state. Various theorists have espoused legal philosophies similar to anarcho-capitalism. One of the first liberals to discuss the possibility of privatizing the protection of individual liberty and property was the French philosopher Jakob Mauvillon in the 18th century. Later in the 1840s, Julius Faucher and Gustave de Molinari advocated the same. In his essay The Production of Security, Molinari argued: "No government should have the right to prevent another government from going into competition with it, or to require consumers of security to come exclusively to it for this commodity". Molinari and this new type of anti-state liberal grounded their reasoning on liberal ideals and classical economics. Historian and libertarian Ralph Raico argued that what these liberal philosophers "had come up with was a form of individualist anarchism, or, as it would be called today, anarcho-capitalism or market anarchism".
Unlike the liberalism of Locke, which saw the state as evolving from society, the anti-state liberals saw a fundamental conflict between the voluntary interactions of people, i.e. society, and the institutions of force, i.e. the state. This society versus state idea was expressed in various ways: natural society vs artificial society, liberty vs authority, society of contract vs society of authority and industrial society vs militant society, to name a few. The anti-state liberal tradition in Europe and the United States continued after Molinari in the early writings of Herbert Spencer and thinkers such as Paul Émile de Puydt and Auberon Herbert. However, the first person to use the term anarcho-capitalism was Murray Rothbard. In the mid-20th century, Rothbard synthesized elements from the Austrian School of economics, classical liberalism and 19th-century American individualist anarchists Lysander Spooner and Benjamin Tucker (while rejecting their labour theory of value and the norms they derived from it). Anarcho-capitalism advocates the elimination of the state in favour of individual sovereignty, private property and free markets. Anarcho-capitalists believe that in the absence of statute (law by decree or legislation), society would improve itself through the discipline of the free market (or what its proponents describe as a "voluntary society").
In a theoretical anarcho-capitalist society, law enforcement, courts and all other security services would be operated by privately funded competitors rather than centrally through taxation. Money and other goods and services would be privately and competitively provided in an open market. Anarcho-capitalists say personal and economic activities under anarcho-capitalism would be regulated by victim-based dispute resolution organizations under tort and contract law rather than by statute through centrally determined punishment under what they describe as "political monopolies". A Rothbardian anarcho-capitalist society would operate under a mutually agreed-upon libertarian "legal code which would be generally accepted, and which the courts would pledge themselves to follow". Although enforcement methods vary, this pact would recognize self-ownership and the non-aggression principle (NAP).
History
Liberal ideas were first drawn together and systematized as a distinct ideology by the English philosopher John Locke, generally regarded as the father of modern liberalism. The first major signs of liberal politics emerged in modern times. These ideas began to coalesce at the time of the English Civil War. The Levellers, a largely ignored minority political movement that primarily consisted of Puritans, Presbyterians, and Quakers, called for freedom of religion, frequent convening of parliament and equality under the law. The Glorious Revolution of 1688 enshrined parliamentary sovereignty and the right of revolution in Britain and was referred to by author Steven Pincus as the "first modern liberal revolution". The development of liberalism continued throughout the 18th century with the burgeoning Enlightenment ideals of the era. This period of profound intellectual vitality questioned old traditions and influenced several European monarchies throughout the 18th century. Political tension between England and its American colonies grew after 1765 and the Seven Years' War over the issue of taxation without representation, culminating in the American Revolutionary War and, eventually, the Declaration of Independence. After the war, the leaders debated about how to move forward. The Articles of Confederation, written in 1776, now appeared inadequate to provide security or even a functional government. The Confederation Congress called a Constitutional Convention in 1787, which resulted in the writing of a new Constitution of the United States establishing a federal government. In the context of the times, the Constitution was a republican and liberal document. It remains one of the oldest liberal governing documents in effect worldwide.
The two key events that marked the triumph of liberalism in France were the abolition of feudalism in France on the night of 4 August 1789, which marked the collapse of feudal and old traditional rights and privileges and restrictions, as well as the passage of the Declaration of the Rights of Man and of the Citizen in August, itself based on the U.S. Declaration of Independence from 1776. During the Napoleonic Wars, the French brought Western Europe the liquidation of the feudal system, the liberalization of property laws, the end of seigneurial dues, the abolition of guilds, the legalization of divorce, the disintegration of Jewish ghettos, the collapse of the Inquisition, the end of the Holy Roman Empire, the elimination of church courts and religious authority, the establishment of the metric system and equality under the law for all men. His most lasting achievement, the Civil Code, served as "an object of emulation all over the globe" but also perpetuated further discrimination against women under the banner of the "natural order".
Criticism and support
Liberalism has drawn criticism and support from various ideological groups throughout its history. Despite these complex relationships, some scholars have argued that liberalism actually "rejects ideological thinking" altogether, largely because such thinking could lead to unrealistic expectations for human society.
Anarchism
Anarchists criticise the liberal social contract, arguing that it creates a state that is "oppressive, violent, corrupt, and inimical to liberty".
Catholicism
One of the most outspoken early critics of liberalism was the Roman Catholic Church, which resulted in lengthy power struggles between national governments and the Church. Christian democracy, a movement associated with modern democracy, hopes to spread Catholic social ideas and has gained a large following in some European nations. The early roots of Christian democracy developed as a reaction against the industrialisation and urbanisation associated with laissez-faire liberalism in the 19th century.
Conservatism
Conservatives have criticised what they perceive as the reckless liberal pursuit of progress and material gains, arguing that such preoccupations undermine traditional social values rooted in community and continuity. However, some variations of conservatism, such as liberal conservatism, expound some of the same ideas and principles championed by classical liberalism, including "small government and thriving capitalism".
Edmund Burke, the first major proponent of modern conservative thought, offered a blistering critique of the French Revolution by assailing the liberal pretensions to the power of rationality and the natural equality of all humans. Nonetheless, Burke was highly influential on other classical liberal thought, and has been praised by both conservatives and liberals alike.
In the book Why Liberalism Failed (2018), Patrick Deneen argued that liberalism has led to income inequality, cultural decline, atomization, nihilism, the erosion of freedoms, and the growth of powerful, centralized bureaucracies. The book also argues that liberalism has replaced old values of community, religion and tradition with self-interest.
Russian President Vladimir Putin believes that "liberalism has become obsolete" and claims that the vast majority of people in the world oppose multiculturalism, immigration, and civil and political rights for LGBTQ people.
Fascism
Fascists accuse liberalism of materialism and a lack of spiritual values. In particular, fascism opposes liberalism for its materialism, rationalism, individualism and utilitarianism. Fascists believe that the liberal emphasis on individual freedom produces national divisiveness, but they generally agree with liberals in their support of private property rights and a market economy.
Feminism
Some feminists argue that liberalism's emphasis on distinguishing between the private and public spheres in society "allow[s] the flourishing of bigotry and intolerance in the private sphere and to require respect for equality only in the public sphere", making "liberalism vulnerable to the right-wing populist attack. Political liberalism has rejected the feminist call to recognize that the personal is political and has relied on political institutions and processes as barriers against illiberalism."
Islam
Liberalism within Islam is supported by some Islamic schools and branches. The Al-Baqara 256 verse in Quran supports liberalism by stating "there is no compulsion in religion". Islamic supremacism, which includes criminal punishment of apostasy in Islam up to capital punishment, opposes liberalism.
Marxism
Karl Marx rejected the foundational aspects of liberal theory, hoping to destroy both the state and the liberal distinction between society and the individual while fusing the two into a collective whole designed to overthrow the developing capitalist order of the 19th century. Vladimir Lenin stated that—in contrast with Marxism—liberal science defends wage slavery; however, some proponents of liberalism, such as Thomas Paine, George Henry Evans, and Silvio Gesell, were critics of wage slavery.
Deng Xiaoping believed that liberalization would destroy the political stability of the People's Republic of China and the Chinese Communist Party, making it difficult for development to take place, and is inherently capitalistic. He termed it "bourgeois liberalization". Thus, some socialists accuse the economic doctrines of liberalism, such as individual economic freedom, of giving rise to what they view as a system of exploitation that goes against the democratic principles of liberalism, while some liberals oppose the wage slavery that the economic doctrines of capitalism allow.
Social democracy
Social democracy is an ideology that advocates for the reform of capitalism in a progressive manner. It emerged in the 20th century and was influenced by socialism. Social democracy aims to address what it perceives as the inherent flaws of capitalism through government reform, with a focus on reducing inequality. Importantly, social democracy does not oppose the state's existence. Several commentators have noted strong similarities between social liberalism and social democracy, with one political scientist calling American liberalism "bootleg social democracy" due to the absence of a significant social democratic tradition in the United States.
