Stefan Lazarevic (Serbian Cyrillic: ?????? ?????????, c.
1377 – 19 July 1427), also known as Stefan the Tall (Serbian: ?????? ?????? / Stefan Visoki), was the ruler of Serbia as prince (1389–1402) and despot (1402–1427).
The son of Prince Lazar Hrebeljanovic, he was regarded as one of the finest knights and military leaders at that time.
After the death of his father at Kosovo (1389), he became ruler of Moravian Serbia and ruled with his mother Milica (a Nemanjic), until he reached adulthood in 1393.
Stefan led troops in several battles as an Ottoman vassal, until asserting independence after receiving the title of despot from the Byzantines in 1402.
Becoming an Hungarian ally in 1403–04, he received large possessions, including the important Belgrade and Golubac Fortress.
He also held the superior rank in the chivalric Order of the Dragon.
During his reign there was a long conflict with his nephew Ðurad Brankovic, which ended in 1412.
Stefan also inherited Zeta, and waged the war against Venice.
Since he was childless, he designated his nephew Ðurad as heir in 1426, a year before his death.
On the domestic front, he broke the resistance of the Serbian nobles, and used the periods of peace to strengthen Serbia politically, economically, culturally and militarily.
In 1412 he issued the Code of Mines, with a separate section on governing of Novo Brdo – the largest mine in the Balkans at that time.
This code increased the development of mining in Serbia, which had been the main economic backbone of the Serbian Despotate.
At the time of his death, Serbia was one of the largest silver producers in Europe.
In the field of architecture, he continued development of the Morava school.
His reign and personal literary works are sometimes associated with early signs of the Renaissance in the Serbian lands.
He introduced knightly tournaments, modern battle tactics, and firearms to Serbia.
He was a great patron of the arts and culture by providing shelter and support to scholars and refugees from neighboring countries that had been taken by the Ottomans.
In addition, he was himself a writer, and his most important work is A Homage to Love, which is characterized by the Renaissance lines.
