Stefan Lazarević

Stefan Lazarević inherited a truncated realm at twelve after his father died at Kosovo in 1389, ruling alongside his mother until 1393. He spent his early years leading troops for the Ottomans, then pivoted after receiving the Byzantine title of despot in 1402 and allying with Hungary - gaining Belgrade, the Golubac Fortress, and a founding seat in the Order of the Dragon. He crushed rival nobles, settled a long feud with his nephew Đurađ Branković (whom he later named heir, having no children), absorbed Zeta, and warred with Venice. In 1412 he issued the Code of Mines to govern Novo Brdo, the Balkans' largest mine, turning Serbia into a European silver giant. A soldier known as one of the finest knights of his age, he also sheltered refugee scholars, wrote A Homage to Love - a work shot through with Renaissance currents - and fostered the Resava School. He died in July 1427; five centuries later the church named him saint.
