Battle of Montiel
Quick Summary
The Battle of Montiel was a pivotal conflict during the First Castilian Civil War. This war was fought between two half-brothers, Peter of Castile and Henry of Trastámara, for the throne of Castile.
Henry, with French support, invaded Castile in 1366 and was crowned king. Peter, seeking English aid, initially regained his throne after the Battle of Nájera in 1367. However, Henry returned with more French troops, leading to a prolonged civil war. The conflict culminated at Montiel in 1369, where Peter was defeated and assassinated by Henry. This victory established Henry II as the king of Castile and founder of the House of Trastámara, which ruled until 1504.12
