The Battle of Magh Slécht took place at Magh Slécht in Ireland in 1256. The battle was part of a wider conflict between the O'Rourke rulers of Breifne and their traditional O'Reilly vassals over control of the kingdom. Both sides were assisted by their respective allies, the O'Connor kings of Connacht and their Burke opponents. The battle marks the site at which the Kingdom of Breifne was left permanently divided, creating West Breifne (O'Rourke) and East Breifne (O'Reilly).
