Stefan Vladislav II
Stefan Vladislav II (c. 1270–after 1326) was the eldest son of King Stefan Dragutin of Serbia and Catherine of Hungary. When Dragutin abdicated to his brother Stefan Milutin in 1282, the succession right of one of his sons was acknowledged. He inherited his father's northern realm of Syrmia in 1316 but was defeated and imprisoned by Milutin.
Freed after Milutin's death in 1321, he claimed the Serbian crown with Hungarian and Bulgarian backing, was beaten by Stefan Dečanski, and retired to Hungary in 1324.
