The Hungarian Kingdom in the 14th century was in conflict with the Ottoman Empire. Louis I of Hungary in Bulgaria was a match for the Turks, but the Wallachian voivods would not support the Hungarians. In the Battle of Nicopolis the Ottoman army crushed the Hungarian-European crusaders and their Wallachian allies. In 1438 Ottoman marauders attacked Transylvania, where in 1437 the Ottomans had been beaten by an uprising under Antal Nagy de Buda. For up to 45 days the Ottomans without let or hindrance attacked the Transylvanian Saxon lands and Hungarian villages and market towns.
