Richard III Plantagenet of England was born in 1390 as the son of Richard II and his wife. While his father hadn't worked on getting revenge for the lost first Aquitainian War, Richard III did so, and planned accordingly. In 1414, England made alliances with Castille and the Netherlands, attacked France again. The second Aquitainian War had begun. In 1424, the Cortes, the Castilian estates, protested the high costs and low results of the war. King Pedro III was sorry about it, but had to leave the war too. He had better things to do, in fact: Interfering in the Portuguese Civil War.
