The Battle of Nicopolis in 1396 was one of the last (together with the expedition to Varna in 1444) crusades in Europe. In it, the Hungarian-Croatian king and emperor of the Holy Roman Empire, Sigismund of Luxembourg, tried to defeat and drive away the Turks, who at that time had approached the Hungarian borders. At that time, the Ottoman Empire was a significant military power that, having already taken over most of the Balkans, posed a real danger of penetrating further into Central Europe.
