The Great Turkish War, also called the Wars of the Holy League, was a series of conflicts between the Ottoman Empire and the Holy League consisting of the Holy Roman Empire, Poland-Lithuania, Venice, Russia, and the Kingdom of Hungary. Intensive fighting began in 1683 and ended with the signing of the Treaty of Karlowitz in 1699. The war was a defeat for the Ottoman Empire, which for the first time lost substantial territory, in Hungary and the Polish–Lithuanian Commonwealth, as well as in part of the western Balkans. The war was significant also for being the first instance of Russia joining an alliance with Western Europe.

The Polish–Lithuanian Commonwealth, formally known as the Kingdom of Poland and the Grand Duchy of Lithuania, or simply Poland–Lithuania, was a bi-confederal state, sometimes called a federation, of Poland and Lithuania ruled by a common monarch in real union, who was both King of Poland and Grand Duke of Lithuania. It was one of the largest and most populous countries of 16th- to 17th-century Europe. At its largest territorial extent, in the early 17th century, the Commonwealth covered almost 1,000,000 km2 (400,000 sq mi) and as of 1618 sustained a multi-ethnic population of almost 12 million. Polish and Latin were the two co-official languages, and Roman Catholicism served as the state religion.
