Ladislaus of Salzburg

Władysław was the fifth and youngest son of the Polish Duke Henry II the Pious, by his wife Anna, daughter of the Přemyslid king Ottokar I of Bohemia.

When he was killed during the first Mongol invasion of Poland in the Battle of Legnica on 9 April 1241, Władysław's eldest brother Bolesław II the Bald assumed the rule over the Lower Silesian lands and the guardianship of his minor siblings.

Stuck in internal conflicts with his brothers Henry III the White and Mieszko, he was not able to secure the Polish throne, which he had to cede to his Piast cousin Konrad of Masovia.

With the approval of their mother Anna of Bohemia and with the purpose to not further divide the paternal lands, the younger sons of late Henry II, Władysław and Konrad I, were sent to study at the Italian university of Padua, with the idea that both prepare for an ecclesiastical career.

Władysław joined the cathedral chapter in Bamberg in 1256 and was elected bishop in the following year, however, he had to resign, as he received no dispensation by Pope Alexander IV due to his young age.

Henry III's government had not been too beneficial to the church; Władysław, now as a bishop and also regent, was not inclined to preserve the prerogatives of the nobility, but at the end he was forced to accept this.

The bishop-regent was an advocate, with his late brother Henry III, for the canonization of their paternal grandmother, Duchess Hedwig of Silesia (née of Andechs).

If the Polish nobles actually wanted to kill him, they presumably would have made this when he stayed in Wrocław and may not have chosen a long journey to Germany to eliminate the bishop-regent.
