Duchy of Legnica
The Silesian Duchy of Legnica since 1248 had been under the rule of Duke Bolesław II Rogatka. When Bolesław's eldest son Henry V the Fat succeeded his father as Duke of Legnica in 1278, he gave the Jawor subdivision to his younger brothers Bolko I the Strict and Bernard the Lightsome. In 1281 Bernard was made a Duke of Lwówek in the western part of the Jawor lands.
