Isabella I of Castile vs Wanyan Aguda

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.

Aguda's Jurchen forces defeated a Liao army at Hubudagang, marking the first major victory of the rebellion. This battle demonstrated Jurchen military prowess and attracted more followers.

Wanyan Aguda united the Jurchen tribes under his leadership, creating a confederation that rebelled against Liao domination. He organized a disciplined army and began the Jurchen revolt.

Wanyan Aguda proclaimed himself emperor, founding the Jin dynasty. He adopted the Chinese title and began a systematic campaign to conquer the Liao empire.

Aguda's forces captured the Liao supreme capital Shangjing, dealing a severe blow to the Liao dynasty. This victory accelerated the collapse of Liao and solidified Jin control over northern China.

Aguda formed an alliance with the Northern Song dynasty to jointly attack the Liao empire. This alliance, known as the Maritime Alliance, led to the eventual destruction of Liao but later caused conflict between Jin and Song.

Wanyan Aguda died, and his brother Wanyan Wuqimai succeeded him. Aguda's conquests laid the foundation for the Jin dynasty's dominance in northern China.
