Bolko I the Strict
Bolko I the Strict (1252/1256–1301) was a Silesian Piast, second son of Bolesław II the Horned of Legnica. After his father died in 1278 he inherited Jawor and ruled it alone from 1281.
Excommunicated in 1294, he defended his towns against King Wenceslaus II of Bohemia in 1295 and made his duchy a papal fief in 1299. He promoted German settlement and founded the Cistercian Krzeszów Abbey, where he was buried after his death on 9 November 1301.
