Charles V ruled more of Europe than anyone since Charlemagne — and spent his life struggling to hold it together. As both Holy Roman Emperor and king of Spain, he commanded an empire spanning Germany, the Low Countries, Spain, Italy and the Americas.
An empire besieged
Charles faced enemies on every side. He fought France again and again for control of Italy, defended Europe against the Ottoman sultan Suleiman the Magnificent, and confronted a force he could not defeat at all: the Reformation. At the Diet of Worms he condemned Martin Luther, but the new faith spread across Germany regardless.
The weary emperor
The burden of ruling so vast a realm in the Renaissance eventually broke even Charles. In a step almost unheard of for a monarch, he abdicated all his crowns, dividing his empire — Spain and the Americas to his son Philip II, the imperial title to his brother — and retired to a monastery to die in peace. His division of the Habsburg inheritance shaped Europe for centuries.
Influence
Charles V's reign was the last great attempt to hold a universal Christian empire together, even as the Reformation and rival powers pulled it apart.
Legacy
His abdication split his empire into the Spanish and Austrian Habsburg lines, shaping European politics for centuries.
