Stefan Lazarevic, also known as Stevan Visoki (born in Kruševac in 1377; died in Glavica near Kragujevac on August 1, 1427) was the son and heir of the Holy Serbian prince Lazar Hrebeljanović, who died in the battle with the Turks in Kosovo (1371-1389). He ruled with the titles of prince (1389-1402) and despot of Serbia. In 1405, he married Jelena, daughter of Francesco II Gatilusius, Lord of Lesbos.

Despot Stefan Lazarević died of a stroke while hunting in 1427 near Crkvine, a hamlet of Markovac village, Mladenovac municipality. He had no children. 1426 at the assembly in Srebrenica, he proclaims his cousin Đurđ Branković as his successor.

The biographer of Saint Stephen the High, the son of Saint Prince Lazar of Serbia and Princess Milica, Constantine the Philosopher, writes that Saint God-Seer Moses was a model and model for Saint God-loving, righteous Stephen the Despot, because the life path of the two was almost the same from the very beginning. Both Moses and Stephen led their God-chosen people through the land of Egyptian and Turkish slavery for about 40 years. He also compared him to Joshua, because he was similar to him in faith and courage, and to the prophet Daniel and the Holy three young men from the furnace of Babylon, because he, like them, was in the jaws of lions and passed through a terrible fire.

He built wonderful endowments, the Mansija and Kalenić monasteries, and was the protector of Christianity in the Balkans in the most difficult days. He is considered one of the greatest Serbian rulers and military leaders, in his time he was considered one of the best knights and military leaders, and his literary works make him one of the greatest Serbian writers in the Middle Ages. During the restoration of the Knighthood of the Dragon, in December 1408, Stefan found himself in second place among the knights, right behind the Hungarian king Sigismund himself.

He rested in the Lord on August 1 (July 19) 1427. The Serbian Orthodox Church canonized him 500 years after his death in 1927 and celebrates him on August 1 (July 19).
