Кёпрюлю
Ottoman dominance in Hungary began with the Battle of Mohács in 1526, which resulted in the conquest of most of Hungary by Suleiman the Magnificent. Meanwhile, the parts of Hungary that remained under Austrian control became known as Royal Hungary. Although the Ottomans had been in relative decline since the death of Suleiman I, Ottoman power saw a resurgence under the extremely capable Köprülü family who sought to destroy the Austrian Habsburgs once and for all. They found their "casus belli" when the Habsburgs supported a Transylvanian rebellion against Ottoman rule.
