The German electors chose the 19-year-old Habsburg king Charles V as Holy Roman Emperor after a costly bribery campaign against French rival Francis I. The election united Spain, the Habsburg Austrian lands, the Low Countries, and Spanish America under a single ruler, creating an empire so vast that contemporaries said the sun never set on it, and setting the stage for a century of Habsburg-Valois conflict.
The election was less a democratic contest than an auction. Charles, already king of Spain and heir to Habsburg lands in Austria and the Netherlands, competed against Francis I of France and briefly Henry VIII of England for the imperial title, and the deciding factor was money. Charles borrowed enormous sums from the Fugger banking family of Augsburg to bribe the seven electors, spending roughly 850,000 florins to secure the crown.
The resulting empire was a geographic marvel and administrative nightmare: Spain and its rapidly expanding American conquests, Austria, the Netherlands, parts of Italy, and the titular authority over the fragmented Holy Roman Empire in Germany. Charles would spend his entire reign crisscrossing this patchwork, fighting the French, negotiating with Protestant princes during the Reformation, and battling Ottoman advances.
The scale of Charles's inheritance reshaped European politics for generations. His rivalry with Francis I sparked repeated wars, and his struggles to contain Martin Luther's Reformation within German lands failed, permanently splitting Western Christianity. Exhausted, Charles abdicated in 1556, dividing his empire between his son Philip II (Spain and the Netherlands) and brother Ferdinand (Austria and the imperial title), a partition whose consequences echoed for centuries.
