Duchy of Legnica
In 1329, Bolesław's youngest brother Władysław (who had been stripped of his Duchy of Legnica in 1312) unexpectedly returned to Silesia. Having been declared a vassal of Bohemia, Władysław took possession of Legnica in the name of King John, leaving Bolesław in a critical situation. Bolesław did not have the resources for a war against King John so, on 9 May 1329 in Wrocław, Bolesław declared himself a vassal of the Kingdom of Bohemia.
