Already during his lifetime, King of Bohemia and the Romans Wenceslas IV was labelled as a bad ruler, who did not take care of the administration of the lands - neither those of the Empire nor the Czech Lands. He was very often accused of the decline of the Church, the inability to resolve the Papal Schism, but also very personal defamations were spread about him in Europe, which were purposefully to deform the image of the king further. One of them is also the accusation for favouring the Jews too much, whom he even favoured against Christians according to some sources. Apparently, Ludolf of Sagan wrote the most extremely in this regard of King of Bohemia and the Romans Wenceslas IV in his work "Tractatus de longevo schismate". Besides many bad characteristics, he directly labelled the sovereign with the title of the Jewish king. However, Ludolf of Sagan was not the only one, who criticized the king for his overprotection of the Jews. The majority of these critics came from the Czech Lands.
