Andronikos II Palaiologos vs Richard the Lionheart

Andronikos II was crowned co-emperor alongside his father Michael VIII, and became sole ruler after Michael's death later that year. His reign began the long Palaiologan dynasty, but the empire was already weakened by financial and military decline.

Andronikos II repudiated the Union of the Churches agreed to by his father at the Second Council of Lyon. He restored Orthodox independence from the Papacy, which pleased the clergy and populace but further isolated Byzantium from the West.

Andronikos II disbanded the Byzantine navy to cut costs, relying instead on Genoese and Venetian mercenaries. This decision left the empire vulnerable to naval attacks and piracy, and contributed to the loss of control over the Aegean islands and trade routes.

During Andronikos II's reign, the Ottoman Turks captured numerous Byzantine cities in Anatolia, including Bursa in 1326. The empire's inability to defend its Asian provinces led to the permanent loss of most of Anatolia, reducing Byzantium to a small state around Constantinople.

Andronikos II faced a civil war against his grandson Andronikos III, who sought to seize the throne. The conflict lasted until 1328, when Andronikos II was forced to abdicate. The civil war drained the empire's resources and allowed the Ottoman Turks to expand in Anatolia.

Richard I led English forces in the siege of Acre during the Third Crusade. After the city surrendered, Richard ordered the execution of 2,700 Muslim prisoners when Saladin failed to meet ransom terms. The victory secured a key port for the crusaders.

Richard I defeated Saladin's forces at Arsuf in Palestine. Richard's disciplined infantry and cavalry repelled repeated Muslim attacks. The victory allowed the crusaders to secure the coast and march toward Jerusalem without further major engagements.

Richard I and Saladin signed a three-year truce at Jaffa. The treaty granted crusader control of the coastal strip from Tyre to Jaffa and guaranteed safe passage for Christian pilgrims to Jerusalem. Richard then departed for Europe.

Richard I was captured near Vienna by Duke Leopold V of Austria, whom he had insulted during the crusade. Leopold handed Richard to Emperor Henry VI. Richard was imprisoned until 1194, when England paid a ransom of 150,000 marks.
