Duke of Wellington vs Isabella I of Castile

Wellington, then Sir Arthur Wellesley, led a British-Indian force to victory against the Maratha Confederacy at Assaye in India. Despite being outnumbered, his tactical skill secured British dominance in central India.

Wellington commanded British forces to defeat the French army at Vimeiro in Portugal. The victory halted the French invasion of Portugal and marked the beginning of the Peninsular War.

Wellington, commanding an Anglo-Allied army, defeated Napoleon Bonaparte at Waterloo in present-day Belgium. The battle ended the Napoleonic Wars and led to Napoleon's final exile to Saint Helena.

Wellington served as Prime Minister of the UK from 1828 to 1830. His government passed the Catholic Relief Act 1829, granting Catholic emancipation, but his opposition to parliamentary reform led to his resignation.

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.
