After the death of Suleiman in 1566, Selim II posed less of a threat to Europe. Though Cyprus was captured at long last, the Ottomans failed against the Habsburgs at sea (see above, Battle of Lepanto). Selim died not too long after, leaving in power his son Murad III, a hedonist who spent more time at his Harem than at the war front. Under such deteriorating circumstances, the Empire found itself at war with the Austrians yet again. In the early stages of the war, the military situation for the Ottomans worsened as the Principalities of Wallachia, Moldova and Transylvania each had new rulers who renounced their vassalship to the Ottomans. At the Battle of Sisak, a group of ghazis sent to raid the insubordinate lands in Croatia were thoroughly defeated by tough Imperial troops fresh from savage fighting in the Low Countries. In response to this defeat, the Grand Vizier launched a large army of 13,000 Janissaries plus numerous European levies against the Christians. When the Janissaries rebelled against the Vizier's demands for a winter campaign, the Ottomans had captured little other than Veszprém.
