The Zrinski-Frankopan Conspiracy was a political plot in the 17th century aimed at opposing the Habsburg rule in Croatia. It involved prominent noble families, particularly the Zrinski and Frankopan families, who sought greater autonomy and power. The conspiracy was fueled by dissatisfaction with the Habsburgs' centralization efforts and their handling of the Ottoman threat. In 1671, the conspiracy was discovered, leading to the arrest and execution of key figures, including Petar Zrinski and Fran Krsto Frankopan. This event marked a significant moment in Croatian history, highlighting the struggle for independence and the resistance against foreign domination.
