Which treaty ended the Ottoman–Habsburg wars in 1699, ceding Hungary to Austria?

The treaty that ended the Ottoman–Habsburg wars in 1699 and ceded much of Hungary to Austria was the Treaty of Karlowitz. It was signed on 26 January 1699 at Karlowitz, now Sremski Karlovci in Serbia.

The agreement concluded the Great Turkish War of 1683–1699, during which the Ottoman Empire fought a coalition known as the Holy League. The war had begun after the failed Ottoman siege of Vienna in 1683 and included major Habsburg victories, especially the Battle of Zenta in 1697.

Under the treaty, the Habsburg monarchy received most of Ottoman Hungary, along with Croatia, Slavonia, and other territories. Transylvania also came under effective Habsburg rule. Venice gained the Morea and parts of Dalmatia, while Poland-Lithuania recovered Podolia. Russia received a temporary truce rather than a full settlement.

Karlowitz marked a major turning point: it was the first large-scale peace treaty in which the Ottoman Empire surrendered substantial European territory after a long period of expansion. The Morea later returned to Ottoman control under the Treaty of Passarowitz in 1718, which is why the two treaties are sometimes confused.
