Magnate conspiracy

The Magnate conspiracy (also known as the Zrinski–Frankopan Conspiracy (Croatian: Zrinsko-frankopanska urota) in Croatia, and Wesselényi conspiracy (Hungarian: Wesselényi-összeesküvés) in Hungary) was a plot among Croatian and Hungarian nobles to oust the Habsburg Monarchy from Croatia and Hungary, in response to the Treaty of Vasvár in 1664. This treaty – which ended the Fourth Austro-Turkish War – was highly unpopular in the Military Frontier, and those who were involved in the conspiracy intended to reopen hostilities with the Ottoman Empire after they broke away from Habsburg rule.^[1]

The attempted coup against Leopold I was led by the Hungarian count Ferenc Wesselényi, the Croatian viceroy Nikola Zrinski, his brother and heir Petar Zrinski, and Petar Zrinski's brother-in-law Fran Krsto Frankopan Frangipane (famiglia).

The Zrinski brothers and their associate Fran Krsto Frankapan were motivated, not only by anger over Emperor Leopold's recent peace agreement with the Ottomans, but even more so by his preference for paying more attention to Western Europe while leaving much of Hungary and Croatia under Turkish rule.^[2]

Similarly to many other European Governments during the 17th century, the Imperial Court was increasingly centralising the administration of the state so they could introduce a more consistent policy of both mercantilism and absolute monarchy.^[2] Similarly to 16th- and 17th-century France, the main obstacle towards a more centralized government was the military and political power and de facto independence of the wealthiest nobles. Instead of succeeding, the Magnate's poorly organized attempt at a regime change revolt and their extremely foolhardy decision to seek Ottoman backing, while at the same time planning to later recapture much more of Croatia and Hungary from rule by both Sharia Law and the House of Osman, caused the Magnate's plans to be leaked to Emperor Leopold and caused the monarch to order a political purge and execute the conspiracy's leaders for high treason.
