King Edward II was born in Caernarfon Castle, Wales on 25 April 1284. He was the fourth son of King Edward I and Eleanor of Castile. Edward's three older brothers died during childhood, leaving him as heir to the throne of England. In 1301, when Edward was just 16, his father bestowed the title 'Prince of Wales' onto him. Later, Edward would grow to become a popular figure in Wales, but would fail to do so in England.

King Edward I was born in Westminster on 17 June 1239, and was the eldest son of King Henry III and Eleanor of Provence. He was named after his father's favourite saint, King Edward the Confessor, a saxon name which was not often given to aristocracy after the Norman conquest.
