The Turkish Wars and the Siege of Vienna

In 1663 rivalries between the Ottomans and the Habsburgs in Transylvania triggered renewed fighting between the Ottoman Empire and the Habsburg Empire. The Turkish threat, which included a prolonged but unsuccessful siege of Vienna in 1683, prompted Poland, Venice, and Russia to join the Habsburg Empire in repelling the Turks. In 1686 Habsburg forces moved into central Hungary and captured Buda. By 1687 the Ottoman Empire had been eliminated as a power in central Hungary. In the late 1690s, command of the imperial forces was entrusted to Prince Eugene of Savoy. Under his leadership, Habsburg forces won control of all but a small portion of Hungary by 1699.
