14th and 15th centuries: the House of Trastámara

The House of Trastámara was a lineage that ruled Castile from 1369 to 1504, Aragón from 1412 to 1516, Navarre from 1425 to 1479, and Naples from 1442 to 1501.

Its name was taken from the Count (or Duke) of Trastámara. This title was used by Henry II of Castile, of the Mercedes, before coming to the throne in 1369, during the civil war with his legitimate brother, King Peter of Castile. John II of Aragón ruled from 1458 to 1479 and upon his death, his daughter became Queen Eleanor of Navarre and his son became King Ferdinand II of Aragon.
