Bolesław IV of Legnica was a Duke of Legnica since 1364.
Background
He was the third son of Wenceslaus I, Duke of Legnica by his wife Anna, daughter of Casimir I, Duke of Cieszyn. After the death of his father in 1364 Bolesław and his siblings (three brothers: Rupert I, Wenceslaus II, and Henry VIII and one sister, Hedwig) were placed under the guardianship of their uncle Louis I the Fair.
Career
In addition, on 2 December 1372 the brothers signed an agreement who declared the indivisibility of the Duchy for the next ten years. In 1365 and at the request of Pope Urban V, the Emperor Charles IV granted Bolesław IV with the rich Prebendary of the Dioceses of Krakow and Wroclaw. However, by 1373 Bolesław IV decided to leave his clergy career and also made his resignation over the actively government of Legnica.
Released from his dynastic obligations, Bolesław IV took a greater interest in the political affairs of that time, notoriously on 6 July 1376, when he participated in the coronation of King Wenceslaus IV in Aachen.
Bolesław IV died without issue between 3 or 4 March 1394, as a result of a fatally wound during a tournament.
