The author presents the stages of the attempt of the Angevins to win the Polish thone during the times of Kazimierz the Great. It is assumed that their rights to the succession after Kazimierz the Great in case of his death without male issue appeared with the marriage of Elizabeth, daughter of Wladyslaw the Short, to Charles Robert, king of Hungary. The Hungarian royal couple kept reminding about their rights to international public. In 1340, after the expedition to Ruthenia, Kazimierz the Great intended to ensure Hungarian support for his eastern policy and made a succession agreement with Charles Robert, in which he promised the Polish throne to his son in case of his death without male heir. The agreement determined Polish-Hungarian relations. In 1350 Louis the Great attempted to force a new interpretation of that agreement in connection with the Hungarian pretenses to Ruthenia. In response to Hungarian proposals, Kazimierz the Great appealed to the people and called a rally to Sulejów in May 1350. From that moment the political elites of Little Poland assumed real control of the succession to the Polish throne and their representatives negotiated the conditions on which Louis the Great would become the king of Poland.
