King Henry IV of Castile died in December 1474, setting off the War of the Castilian Succession between Henry's daughter Joanna la Beltraneja and Henry's half-sister Isabella. The war raged from 1475–1479, pitting Isabella's supporters and the Crown of Aragon against Joanna's supporters, Portugal, and France. During this time, the frontier with Granada was practically ignored; the Castilians did not even bother to ask for or obtain reparation for a raid in 1477. Truces were agreed upon in 1475, 1476, and 1478. In 1479, the Succession War concluded with Isabella victorious. As Isabella had married Ferdinand of Aragon in 1469, this meant that the two powerful kingdoms of Castile and Aragon would stand united, free from the inter-Christian strife which had allowed the Emirate of Granada to survive.
