Spanish Habsburgs
Spain / Holy Roman Empire · 1516 – 1700
Overview
The Spanish Habsburg dynasty inherited, at a single moment in 1516, the largest territorial state in the world. Charles V was simultaneously king of Castile and Aragon through his mother Joanna; king of Naples, Sicily, and Sardinia through his Aragonese inheritance; ruler of Spanish America through the same; Duke of Burgundy and Lord of the Netherlands through his grandmother Mary of Burgundy; and from 1519 Holy Roman Emperor, archduke of Austria, and king of the Romans through his Habsburg patrimony. He was nineteen years old.
Charles abdicated forty years later in stages between 1554 and 1556, exhausted by four decades of universal war and convinced no successor could manage the whole inheritance. His son Philip II received Spain, the Indies, the Italian possessions, and the Low Countries; his brother Ferdinand received the Austrian lands and ultimately the imperial title. The Spanish branch would reign in Madrid for the next century and a half, defending a global empire against the rising powers of England, France, the Netherlands, and the Ottomans.
The reign of Philip II (1556–1598) is the apex of Spanish Habsburg power. The Spanish silver fleets brought back the wealth of the Americas; the Battle of Lepanto in 1571 broke Ottoman naval supremacy in the Mediterranean; in 1580 Philip inherited the throne of Portugal, briefly uniting the two Iberian empires. The reign also saw the catastrophic Dutch Revolt, the failed Armada against Elizabethan England (1588), and the religious wars of the French Reformation in which Philip backed the losing Catholic League.
The dynasty entered visible decline under his successors. Repeated cousin marriages — designed to keep the inheritance within the Habsburg family — produced increasingly inbred offspring; the last Spanish Habsburg, Carlos II, was so disabled by genetic damage that he could not chew solid food, walk unaided, or father an heir. His death in 1700 without issue triggered the War of the Spanish Succession, which ended the dynasty and brought the French Bourbons to the Spanish throne under the Treaty of Utrecht.

A two-year campaign by Hernán Cortés and roughly six hundred Spaniards, aided by smallpox and tens of thousands of indigenous allies who hated Mexica rule, destroyed the Aztec Empire. Moctezuma II received Cortés peacefully in Tenochtitlan in November 1519 and was held captive there; he died in disputed circumstances during the Mexica uprising of 1520. The eighty-day Spanish siege ended on 13 August 1521 with the capture of the last tlatoani, Cuauhtémoc.

On 25 July 1554 Mary Tudor married her cousin Philip of Spain, son of the Holy Roman Emperor Charles V, in Winchester Cathedral. The match was deeply unpopular in England — a Catholic prince of the rising Habsburg superpower marrying the reigning queen on terms widely seen as compromising English sovereignty. The marriage produced no children; on Mary's death Philip lost his English title and pursued the throne through war against her Protestant successor Elizabeth.

Between 1554 and 1556 Charles V, exhausted by four decades of universal war, partitioned the empire he had inherited intact. His son Philip received Spain, the Indies, the Italian possessions, and the Low Countries; his brother Ferdinand received Austria, Bohemia, Hungary, and ultimately the imperial title. The split divided the Habsburgs into Spanish and Austrian branches that would remain cousin powers for the next century and a half. Charles retired to a monastery in Yuste and died there in 1558.
Also involved: Austrian Habsburgs (received the imperial and Austrian inheritance)
Philip II of Spain assembled the Grande y Felicísima Armada — 130 ships, 30,000 men — to invade Elizabethan England, depose its Protestant queen, and reclaim the English throne for Catholicism. English long-range gunnery, fireships at Calais, and the great Atlantic gales drove the fleet north around Scotland and Ireland; perhaps half the ships and most of the men never returned to Spain. The defeat ended Spain's century-long dominance of European warfare.
