Upon his untimely death, John's eldest son Henry came to the throne as Henry III, at the very young age of twelve. He waited only two years to independently take control of the throne in 1393 at only fourteen, amidst a great deal of violence being carried out against Jews throughout Castile. Among the young king's accomplishments was his taking of control of the Canary Islands, providing Castile with a holding in the Atlantic Ocean. In 1406, amidst an invasion by Granada's forces in Murcia, Henry died while planning a response at the age of 27.
