In spite of this success, the ransom for Čengić was taken away from him upon the complaint of general Herbert Auersperg, who previously withdrew to Carniola from Karlovac. Zrinski-Frankopan plot During the Austro–Turkish War (1663–1664) Petar Zrinski fought the Turks at the siege of Novi Zrin Castle along with his brother Nikola. After the unpopular Peace of Vasvár (1664) between Holy Roman Emperor Leopold I and the Ottoman Empire, he joined Croatian and Hungarian nobility who were disappointed by the failure to remove the Ottomans completely from Hungarian territory and embarked on a conspiracy to remove foreign influence, including Habsburg rule, from the Lands of the Crown of St. Stephen.

Finding themselves in a desperate position, they finally went to Vienna to ask emperor Leopold I of the Habsburg dynasty for pardon. They were offered safe conduct but were arrested. A tribunal chaired by chancellor Johann Paul Hocher sentenced them to death for high treason on 23 and 25 April 1671. For Petar Zrinski the verdict was read as follows: ...he committed the greater sin than the
