Colonel Josias Jackson was a British military officer and politician who represented Southampton in the House of Commons of the United Kingdom from 1807 to 1812. Born into the planter class of the British West Indies, Jackson fought in the Second Carib War in 1795 before moving to Portsmouth, England, in 1803. There, he became colonel of a British Volunteer Corps unit before becoming a member of parliament for Southampton for five years. During his time in the British Parliament, Jackson defended slavery and plantation owners. Following the end of his political career in England he returned to Saint Vincent and sat on the island's council. The slave plantations he owned were divided among his sons after Jackson's death in 1819.
