Afonso de Albuquerque vs Isabella I of Castile

Afonso de Albuquerque led a fleet to India, establishing the first Portuguese fort at Cochin. This voyage laid the foundation for Portuguese control of the Indian Ocean trade.

Albuquerque captured Goa from the Sultan of Bijapur. He made Goa the capital of Portuguese India, a position it held for over 400 years.

Albuquerque led a Portuguese fleet to capture the strategic port of Malacca. This gave Portugal control of the spice trade route between the Indian Ocean and the Pacific.

Albuquerque attempted to capture Aden in Yemen but failed. This failure prevented Portugal from controlling the entrance to the Red Sea and limited their influence in the region.

Afonso de Albuquerque died at sea off the coast of Goa, possibly from illness or poison. His death left the Portuguese Empire in the Indian Ocean without its most capable leader.

Isabella married Ferdinand II of Aragon in Valladolid, uniting the kingdoms of Castile and Aragon. This dynastic union laid the foundation for the unified Spanish monarchy and enabled joint policies including the Reconquista and overseas exploration.

Isabella obtained papal approval to establish the Spanish Inquisition in Castile, aimed at maintaining Catholic orthodoxy among converted Jews and Muslims. The Inquisition operated under royal control, conducting trials and executions for heresy.

Isabella and Ferdinand completed the Reconquista by capturing the Nasrid kingdom of Granada. The surrender of the last Muslim state in Iberia ended 781 years of Islamic rule and unified Spain under Christian rule.

Isabella and Ferdinand issued the Alhambra Decree ordering the expulsion of all Jews from Spain who refused conversion to Catholicism. An estimated 40,000 to 200,000 Jews were forced to leave, causing demographic and economic disruption.

Isabella agreed to fund Christopher Columbus's expedition across the Atlantic, providing three ships and supplies. Columbus reached the Bahamas on October 12, initiating sustained European contact with the Americas and the Spanish colonial empire.

Isabella and Ferdinand negotiated the Treaty of Tordesillas with Portugal, dividing newly discovered lands outside Europe along a meridian 370 leagues west of the Cape Verde islands. This agreement shaped colonial claims in the Americas and Africa.
