What happened at the Defenestration of Prague

On 23 May 1618, a group of Protestant Bohemian nobles, angered by Habsburg efforts to curb their religious and political rights, stormed a chamber in Prague Castle and threw two royal regents and their secretary from a window. The men survived the fall, but the act was a direct challenge to Habsburg authority under Ferdinand, then King of Bohemia and later Emperor Ferdinand II. It led the Bohemian estates to reject Habsburg rule and seek a new king, sparking the Bohemian Revolt. This conflict escalated into the Thirty Years' War (1618 to 1648), a devastating struggle involving most of Europe's major powers, fought over religion, territory, and dynastic power, and one of the deadliest conflicts in early-modern European history.
