In short: Đurađ Branković, a Serbian despot, fought the Ottomans with 3,000 knights against 60,000, built a library of rare manuscripts, and died as the last Christian ruler of Serbia. His story is one of survival, culture, and resistance in the face of overwhelming odds.

Đurađ Branković, known as George Branković, was the last Christian ruler of medieval Serbia, holding power from 1427 to 1456. His rule was marked by a complex relationship with the Ottoman Empire, as he was both a vassal and a strategic ally. Despite this, he sought to strengthen Christian alliances and maintain the cultural and political independence of his realm. His most iconic achievement was the construction of the Smederevo Fortress, which became the final capital of medieval Christian Serbia. This fortress was not only a military stronghold but also a symbol of resistance against the Ottoman advance.

Branković's life was shaped by the broader geopolitical struggles of the late 14th and early 15th centuries. He was the offspring of Vuk Branković and Mara Lazarević, who was the child of Prince Lazar Hrebeljanović, while his spouse, Eirene Kantakouzene, held the title of Byzantine princess. His early life was influenced by the conflicts between the Serbian nobility and the Ottoman Empire, particularly the rivalry with his uncle, Stefan Lazarević. This rivalry led to a prolonged domestic conflict that lasted for ten years. Branković's eventual ascension to power was secured through his uncle's will, which named him as his heir.

As a despot, Branković faced constant threats from both the Ottomans and the Hungarian crown. His efforts to maintain control over territories like Belgrade and Golubac were met with resistance, particularly from the commander of Golubac, Duke Jeremija, who refused to hand over the city to the Hungarians without a substantial bribe. Branković's military campaigns, such as the defense of Belgrade in 1456, highlight his strategic acumen and personal bravery. However, his reign also saw significant cultural contributions, including the establishment of a vast library of manuscripts that made Smederevo a center of Serbian learning and culture.

The fall of Smederevo in 1439 marked a turning point, forcing Branković to flee to Hungary, where he retained significant estates. Despite this, he continued to play a pivotal role in regional politics, including the Peace of Szeged in 1444, which temporarily restored his rule. His death in 1456 did not end Serbian resistance, as his lands were eventually annexed by the Ottoman Empire, but his legacy endured through his cultural contributions and the resilience of his people.
