Kyansittha vs Philip III of France

After succeeding King Sawlu, Kyansittha suppressed a Mon rebellion and stabilized the Pagan Empire. He implemented administrative reforms, promoted Theravada Buddhism, and fostered cultural exchange with the Mon people, strengthening the empire's unity and laying the foundation for its golden age.

Kyansittha actively promoted Theravada Buddhism as the state religion, building numerous monasteries and stupas. He invited Buddhist monks from Sri Lanka and the Mon region to spread the faith, which became a unifying force in the Pagan Empire and shaped Burmese religious identity.

King Kyansittha commissioned the construction of the Ananda Temple in Bagan, one of the finest examples of Mon-style Buddhist architecture. The temple, completed around 1105, features four standing Buddha statues and intricate carvings, and remains a major pilgrimage site and symbol of Pagan's cultural achievement.

Philip III's father, Louis IX, signed the Treaty of Corbeil, which renounced French claims to Catalonia and Roussillon in exchange for Aragonese renunciation of claims to Provence and Languedoc. Philip III inherited this settlement.

Philip III invaded Navarre to enforce his claim as regent for his niece, Joan I of Navarre. He secured control of the kingdom, which later passed to his son Philip IV through marriage, expanding French influence in the Pyrenees.

Philip III led the Aragonese Crusade, a papal-sanctioned invasion of Aragon to depose King Peter III. The French army was defeated at the Battle of the Col de Panissars and forced to retreat, suffering heavy losses. Philip III died during the retreat.
