To the southwest of Europe, events in Iberia would eventually bring about several changes that would usher in the end of Europe’s Middle Ages and the beginnings of modern times.
Portugal, Castile, and Aragon were steeped in the traditions of the Reconquista , of expanding the dominion of the Christian world by force of arms. The Reconquista had established a habit in the Iberian kingdoms of conquering Muslims lands and reducing their Muslim and Jewish inhabitants to subordinate status (or in some cases to outright slavery). By the fifteenth century, these kingdoms had nearly completed the Reconquista . As stated earlier, only Granada remained under Muslim rule.
Meanwhile, over the fourteenth century, both Venice and the Ottoman Empire had forced the Italian city-state of Genoa out of the Eastern Mediterranean, so its sailors and ship owners turned their focus to the western half of the Mediterranean Sea. Constantly on the lookout for new markets, Genoese merchants already knew from trade with the Islamic Maghreb that West Africa was a source of gold. In 1324, Mansa Musa’s hajj to Mecca (see Chapter Nine) had put so much gold into circulation that the price of gold fell by twenty-five percent in the Mediterranean market. If the Muslim rulers of Morocco controlled the overland routes by which gold traveled from Mali to the Mediterranean, then perhaps certain sailors could bypass the overland route by sailing into the Atlantic and around the Sahara and arrive at the source of Africa’s gold.
By 1300, the combination of the compass, a map called the portolan (a map that could accurately represent coastlines), and ships that by operating on sails rather than oars needed fewer people meant that European navigators could begin venturing into open waters of the Atlantic that the Arabs and Ancient Romans had largely avoided.
Genoese merchants began tentatively sailing into the Atlantic. In the early 1300s, they were regularly visiting the Canary Islands. These merchants (and others from Western Europe) increasingly served in the employ of Iberian kings. In 1404, King Henry III of Castile (r. 1390 – 1406) began Spanish efforts to conquer the Canaries and convert their indigenous peoples to Christianity. Over the next century, the Spanish would conquer and settle the islands, driven by the Reconquista ideal of the military spread of the Christian faith. In the mid-fifteenth century, the kingdom of Portugal began the conquest and colonization of the Azores, nearly 700 miles to the southwest of Iberia in the Atlantic.
Genoese merchants established sugar plantations on these chains of islands, and those plantations were worked by slave labor. Earlier, in the thirteenth century, Venetian merchants had begun to grow sugar (long cultivated in the Muslim world) in their island colonies in the Mediterranean, and labor for these colonies came from the Mediterranean slave trade. Genoese merchants copied this economic model first in Sicily and then, when they began to operate in the Atlantic, in the Canaries and Azores. Often they would purchase the slaves for these plantations from Africans on the continent’s Atlantic coast. Thus began a slave trade that would be as lucrative for its operators as it was brutal for its victims.
The lure of African gold drew mariners serving Iberian monarchs south and west. By 1482, the Portuguese had established the fort and trading post of São Jorge da Mina on the coast of Guinea. And in the Iberian peninsula, in 1479, Isabella, the Queen of Castile, married King Ferdinand II of Aragon, creating a united Spanish kingdom. In 1492, these monarchs, devout Catholics both, completed the Reconquista , conquering Granada, the last Muslim territory in Spain. All of Spain was now under Christian rule, and the king and queen were eager to continue spreading the Catholic religion.
They sponsored a voyage by the Genoese sailor Christopher Columbus. Columbus had miscalculated the size of the world, so he believed that it would be possible to sail to Asia by traveling west across the Atlantic Ocean. European mariners knew the world was a sphere but believed that it was impossible to carry adequate supplies to sail around the world due to the sheer distance between Europe and Asia. When Columbus made landfall in 1492, it was not in East Asia (for he had in fact been wrong, drastically underestimating the size of the world), but rather in a set of lands previously unknown to the peoples of the Eastern Hemisphere. The world was about to be forever changed.
