of it to organize together with the Kingdom of Hungary a campaign against the Turks. The Hungarians, Poles and Wallachians were defeated at the Battle of Varna in 1444, and Constantinople finally fell in 1453 to the Turks, followed by the Despotate of Morea in 1460, the Empire of Trebizond in 1461, and the Principality of Theodoro in 1475, which brought an end to the last vestiges of the Eastern Roman Empire, as well as the final remaining pockets of Greek resistance against the Ottoman Turks in both the Balkans and Anatolia. The Battle of Nicopolis is also widely regarded as the end of the Second Bulgarian Empire, since hopes for its revival had come to an end with the defeat of the Crusaders. Its last ruler, Ivan Sratsimir of Bulgaria, was captured and killed in Bursa. By their victory at Nicopolis, the Turks discouraged the formation of future European coalitions against them. They maintained their pressure on Constantinople, tightened their control over the Balkans, and became a greater threat to central Europe.
