The Fifteen Years War was fought between Austria and the Ottoman Empire between 1591 and 1906. After initial Turkish advances against the Austrians, Bathory, prince of Transylvania, in 1595 allied with Holy Roman Emperor Rudolf II. The Turks invaded Transylvania but were driven out. The Habsburgs occupied Hungary, but then Bocskay, with Turkish aid, fomented a revolt in Transylvania and drove the Habsburgs from Hungary in 1606. The war marked the ascendance of Transylvania as a political power, and demonstrated a decline in Ottoman imperial power in Europe. Research Fifteen Years War
