Ivan Asen I vs James I of Aragon

Ivan Asen I, along with his brother Peter IV, led a successful uprising of Bulgarians and Vlachs against Byzantine rule. The rebellion began in Tarnovo and quickly spread, leading to the restoration of the Bulgarian state.

Ivan Asen I and his brother Peter IV established the Second Bulgarian Empire with its capital at Tarnovo. They were crowned co-emperors, marking the restoration of Bulgarian independence after nearly 170 years of Byzantine rule.

Ivan Asen I was assassinated by his cousin Ivanko, a boyar, during a period of internal conflict. His death temporarily destabilized the Second Bulgarian Empire, but his brother Peter IV continued to rule.

James I led a fleet from Salou to invade the island of Mallorca, defeating the Almohad governor. The conquest added the Balearic Islands to the Crown of Aragon and established a base for Mediterranean trade.

James I captured the city of Valencia after a long siege, incorporating the Kingdom of Valencia into the Crown of Aragon. The conquest added a wealthy and populous territory to Aragon and extended Christian control down the Mediterranean coast.

James I signed the Treaty of Corbeil with Louis IX of France, renouncing Aragonese claims to territories in southern France in exchange for French recognition of Aragonese rule over Roussillon and Montpellier. This treaty defined the border between France and Aragon.

James I granted the Kingdom of Valencia its own legal code, the Furs, which established a separate legal and administrative system for the new kingdom. This code balanced royal authority with local privileges and became a model for later Aragonese governance.
