Spanish Empire
The Spanish Empire existed for nearly five centuries, from 1492 to 1976, stretching across the Americas, Africa, Asia, and Oceania. It became so vast that contemporaries called it "the empire on which the sun never sets." At its greatest extent in the late 1700s and early 1800s, it ranked among the largest empires in history. A French traveler passing through Spain in 1603 noted a local saying: "Everything is dear in Spain except silver." That quip cuts to the heart of a paradox the empire never resolved. Gold and silver poured in from mines in Zacatecas, Guanajuato, and Potosi. Yet the wealth enriched foreign merchants and mercenary armies far more than ordinary Spaniards. How did a colonial project that began with a Genoese sailor seeking Japan end up spanning the globe? How did it hold together for three hundred years, and what finally broke it apart?
Ferdinand of Aragon and Isabella of Castile did not rule a single unified kingdom; they presided over two separate crowns with distinct laws, administrations, and armies. Their marriage was a personal union, not a merger. Together the House of Trastamara joined the economic and military resources of Iberia under one dynasty. Isabella's court at Salamanca, Valladolid, and Alcala trained a new class of lawyer-bureaucrats, university graduates called letrados and licenciados, who would staff the councils governing the New World.
Pope Alexander VI, born in Valencia, rewarded the pair with the title of the Catholic Monarchs after their forces completed the Christian conquest of Granada in 1492, ending a ten-year war against the Muslim emirate there. Ferdinand's eye was trained on France and Italy; he joined the League of Cambrai against Venice in 1508 and manoeuvred for control of Milan and Navarre over the following decade. Isabella's court proved more open to overseas ventures. In the Capitulations of Santa Fe, signed on the 17th of April 1492, a Genoese mariner named Christopher Columbus received his appointment as viceroy and governor over any lands he might discover, making it the first document to establish an administrative framework for the Indies.
The Canary Islands, inhabited by Guanche people, had been under conquest since 1402, when Norman nobleman Jean de Bethencourt began the campaign under a feudal agreement with Henry III of Castile. The Crown's armies finished the job between 1478 and 1496, taking Gran Canaria, La Palma, and Tenerife in sequence. By 1504, more than 90 percent of the indigenous Canarians had been killed or enslaved. That brutal template would repeat across the Atlantic.
Portugal had a head start. Its navigators had colonised Madeira in 1418 and the Azores between 1427 and 1452, and had reached the Gold Coast in 1471. When news of the Guinea gold spread through the ports of Andalusia, chronicler Hernando del Pulgar wrote that "everybody tried to go there." Castile tried to muscle in during the War of the Castilian Succession, but a Portuguese fleet intercepted a Castilian armada of 25 ships sent to conquer Gran Canaria in 1478, capturing five of them and 200 Castilians.
The Treaty of Alcacovas, signed on the 4th of September 1479, reflected that naval defeat. Castile kept the Canary Islands but recognized Portugal as sole proprietor of the African coast and the other Atlantic islands. It was a serious setback, and it had an unintended consequence. Blocked from sailing south and east, Castile was pushed to sponsor Columbus's westward voyage in 1492. The gamble paid off in unexpected fashion: Columbus encountered not Asia but the Americas.
Castile locked in its claim with papal bulls dated the 4th of May 1493 and the 26th of September 1493. The two Iberian powers then negotiated a lasting arrangement in the Treaty of Tordesillas, dated the 7th of June 1494, splitting the non-Christian world along a north-south line. Portugal received Africa and Asia; Spain received the Western Hemisphere, later excepting Brazil, which Portuguese commander Pedro Alvares Cabral encountered in 1500. Pope Julius II confirmed the treaty in the bull Ea quae pro bono pacis on the 24th of January 1506. Francis I of France dismissed the whole arrangement, asking to see the clause in Adam's will that excluded him from a share of the world.
Hernan Cortes sailed for the coast of Mexico in March 1519 with 550 conquistadors, defying the orders of Diego Velazquez de Cuellar, the governor of Hispaniola. His forces defeated a 10,000-strong Chontal Mayan army at Potonchan on the 24th of March, then routed a force of 40,000 Mayans three days later. On the 2nd of September, 360 Castilians and 2,300 Totonac allies defeated a 20,000-strong Tlaxcalan army. Three days after that, a force of 50,000 Otomi-Tlaxcalan warriors was broken by arquebusier fire, cannon, and a cavalry charge. Thousands of Tlaxcalans then switched sides, joining the invaders against their Aztec overlords.
Cortes sacked Cholula, massacring 6,000 inhabitants, before entering the Aztec capital Tenochtitlan on the 8th of November. When Pedro de Alvarado triggered an uprising by massacring 400 Aztec nobles and 2,000 onlookers at the Great Temple, the Castilians were driven out during La Noche Triste, losing all their gold and artillery. At Otumba on the 8th of July 1520, without arquebuses or cannon, the Spanish and their allies repelled a force of 100,000 Aztecs armed with obsidian-bladed clubs.
The siege of Tenochtitlan began in May 1521. Thirteen Spanish brigantines sank 300 of 400 Aztec war canoes. The Aztecs hid spears beneath shallow water to damage Spanish vessels. Fighting moved street by street. The city fell on the 14th of August 1521, with the capture of the new emperor Cuauhtemoc. At least 100,000 Aztecs died during the siege; the Spanish lost roughly 100 soldiers, and up to 30,000 of their indigenous allies were killed or died from disease. Francisco Pizarro replicated the pattern in 1532, capturing the Inca leader Atahualpa in a surprise attack at Cajamarca that also resulted in a massacre. The Viceroyalty of New Spain was formally established in 1535, and the Viceroyalty of Peru followed in 1542.
Philip II of Spain, who ruled from 1556 to 1598, oversaw a global empire that included the Philippines, colonised from 1565 under Miguel Lopez de Legazpi, as well as southern Italy, the Low Countries, and the annexed Portuguese empire after 1580. The mines of Zacatecas, Guanajuato, and Potosi supplied the crown with enormous quantities of precious metal. Silver production in New Spain more than tripled between the start of the 18th century and the 1750s.
Yet the Habsburg dynasty spent those riches faster than they arrived. The crown pursued wars across Europe against France, the Ottoman Empire, Protestant rebels in the Low Countries, and various Italian rivals. It declared moratoriums on its debt payments multiple times. The problems caused by inflation were debated by scholars at the School of Salamanca and by the arbitristas, a class of policy writers who recognized the trap: resource wealth reduced the incentive to build industry. Wealthy Spaniards preferred to park money in public debt, known as juros, rather than invest in manufacturing. Most goods exported to the colonies came from manufacturers in northwest Europe, not Spain. As one historian put it, the wealth of the Indies impoverished Spain and enriched northern Europe.
Genoese bankers provided much of the financial scaffolding that held the empire together, financing royal expeditions and military campaigns. Without that credit network, the whole edifice would have collapsed far sooner. The Dutch, English, and French managed to take only small Caribbean islands and coastal outposts from Spain, using them to run contraband trade with Spanish colonists. Spain's mercantilist system was porous by design as much as by failure.
Charles II of Spain died in 1700 without an heir, setting off the War of the Spanish Succession. Under the Treaties of Utrecht, signed on the 11th of April 1713, Philippe of Anjou, grandson of Louis XIV, became King Philip V of Spain, founding the Bourbon dynasty there. The settlement cost Spain its European territories: the Spanish Netherlands, Naples, Milan, and Sardinia went to Austria; Sicily and parts of Milan went to the Duchy of Savoy; Gibraltar and Menorca went to Britain. British merchants also received the asiento de negros, the exclusive right to sell enslaved people in Spanish America for thirty years.
Philip V reorganised the government along French lines, replacing the old council system with executive ministries. His government created the Ministry of the Navy and the Indies in 1714 and established trading companies including the Havana Company in 1740 and the Barcelona Trading Company in 1755. In 1717-18, the administrative bodies governing Indies trade were moved from Seville to Cadiz, where foreign merchant houses had easier access. Silver flowed more reliably, shipping grew rapidly from the mid-1740s, and by the 1780s Catalan textile manufacturing showed the first signs of industrialisation.
Two upheavals revealed the tensions beneath the reformed surface. The Tupac Amaru uprising in Peru in 1780 and the rebellion of the comuneros of New Granada were both, in part, reactions to tighter crown control. When Napoleon's forces invaded the Iberian peninsula in 1808 and placed his brother Joseph Bonaparte on the Spanish throne, it triggered a legitimacy crisis across Spanish America. By the mid-1820s, Spain had lost Mexico, Central America, and South America. Simón Bolivar led campaigns winning independence for the area that became Venezuela, Colombia, Ecuador, Peru, and Bolivia between 1811 and 1826. The Spanish-American War in 1898 then stripped Cuba, Puerto Rico, Guam, and the Philippines. The last Spanish garrison in the Philippines, besieged in Baler, Aurora, was finally pulled out on the 2nd of June 1899, ending roughly 300 years of Spanish rule in the archipelago.
Spain's African possessions outlasted its American empire by decades. Fernando Po, now known as Bioko, was ceded to Spain by Portugal in 1778 in exchange for territory in South America under the Treaty of El Pardo. Rio Muni became a Spanish protectorate in 1885 and a colony in 1900. In 1860, following the Tetuan War, Morocco paid Spain 100 million pesetas in war reparations and ceded Sidi Ifni under the Treaty of Tangiers.
The Battle of Annual in 1921 during the Rif War was a catastrophic defeat for the Spanish army at the hands of Moroccan insurgents led by Abdelkrim, a former officer in the Spanish administration. A leading Spanish politician declared: "We are at the most acute period of Spanish decadence." Spain responded by deploying German chemical weapons against the Moroccan fighters. The Alhucemas landing in September 1925, combining Spanish army, navy, and a French contingent, ended the Rif War; it is described as the first successful amphibious landing in history supported by seaborne air power and tanks.
Bioko and Rio Muni were united as Spanish Guinea in 1926. First local elections there were held in 1959, and the territory's first representatives took seats in the Spanish parliament that year. In March 1968, under pressure from Equatoguinean nationalists and the United Nations, Spain announced it would grant independence. Spain surrendered Spanish Morocco to the newly independent Moroccan state in 1956, returned Sidi Ifni to Morocco under international pressure in 1969, and withdrew from Spanish Sahara in 1975 following Morocco's Green March. Morocco still claims Ceuta and Melilla, both of which remain Spanish territory internationally recognised as administrative divisions of Spain.
Common questions
When did the Spanish Empire begin and end?
The Spanish Empire existed from 1492, with Christopher Columbus's first voyage, until 1976, making it one of the longest-lived colonial empires in history.
What was the Treaty of Tordesillas?
Signed on the 7th of June 1494, the Treaty of Tordesillas divided the non-Christian world between Spain and Portugal along a north-south line. Portugal received Africa and Asia; Spain received the Western Hemisphere, with the later exception of Brazil.
Why did Spain's enormous silver wealth not make it prosperous?
Most of the silver from mines in Zacatecas, Guanajuato, and Potosi went toward paying mercenary soldiers and purchasing manufactured goods from northern Europe. The influx also reduced incentives for domestic industry, and wealthy Spaniards invested in government debt rather than manufacturing. Scholars at the School of Salamanca debated the resulting inflation.
What triggered the independence movements in Spanish America?
Napoleon's invasion of the Iberian peninsula in 1808 and his placement of his brother Joseph Bonaparte on the Spanish throne created a legitimacy crisis across Spanish America. Bourbon reforms had already strained relations with colonial elites, and local militias that had defeated British forces in 1807 gained the confidence to pursue independence.
What were the Bourbon Reforms?
The Bourbon Reforms were a series of administrative and economic changes introduced after Philip V took the Spanish throne in 1700. They included centralising power via the Nueva Planta decrees, moving Indies trade administration from Seville to Cadiz, establishing new trading companies, and loosening trade controls to stimulate colonial commerce.
When did Spain lose its last overseas territories?
Following the Spanish-American War, the Treaty of Paris in 1898 ceded Cuba, Puerto Rico, and Guam to the United States, and the Philippines were sold for 20 million US dollars. The final Spanish garrison in the Philippines was withdrawn on the 2nd of June 1899. Spain's African territories lasted longer, with Spanish Sahara relinquished in 1975.
