Overview
Bolko (Bolesław) I the Strict also known as the Raw or of Jawor ( or Srogi or Jaworski; ; 1252/56 – 9 November 1301), was a Duke of Lwówek (Löwenberg) 1278–81 (with his brother as co-ruler) and Jawor (Jauer) after 1278 (with his brother as co-ruler until 1281), sole Duke of Lwówek after 1286, Duke of Świdnica-Ziębice from 1291.
Life
Bolko I was the second son of Bolesław II the Bald, Duke of Legnica by his first wife Hedwig, daughter of Henry I, Count of Anhalt.
Most likely because he was still too young to actively participate in politics, Bolko appears rarely in the chronicles before his father's death. It is possible that he took part in the victorious Battle of Stolec in 1277.
Bolesław II died on 26 December 1278. Bolko I and his younger brother Bernard the Lightsome inherited Jawor (Jauer) and Lwówek (Löwenberg) as co-rulers, and their older brother Henry V the Fat retained Legnica. In 1281 Bolko I and Bernard divided their domains: Bernard kept Lwówek, and Bolko I became in sole ruler of Jawor.
