Europe entered the twentieth century thick with kings, kaisers, and tsars bound together by blood and treaty, and this History Hit documentary traces how two world wars stripped most of them from their thrones. It follows the fall of the Romanovs in Russia, ending in the execution of Nicholas II and his family, and the collapse of the Hohenzollern and Habsburg crowns as Kaiser Wilhelm II abdicates and the Austro-Hungarian empire is carved into republics. Historians walk through the family ties that once linked these dynasties as cousins and allies, and how those same connections failed to stop the continent tearing itself apart. The film also looks at the monarchies that survived, Britain's among them, and asks what allowed a handful of royal houses to adapt while others were swept away entirely. Archival photographs, palace footage, and expert interviews carry the narrative through abdications, revolutions, and the redrawing of Europe's map, ending with the diminished, largely ceremonial monarchy that remains today.
