Edward II (25 April 1284 – 21 September 1327), also called Edward of Caernarfon, was King of England and Lord of Ireland from 1307 until he was deposed in January 1327. The fourth son of Edward I, Edward became the heir apparent to the throne following the death of his elder brother Alphonso. Beginning in 1300, Edward accompanied his father on invasions of Scotland. In 1306, he was knighted in a grand ceremony at Westminster Abbey. Following his father's death, Edward succeeded to the throne in 1307. He married Isabella, the daughter of the powerful King Philip IV of France, in 1308, as part of a long-running effort to resolve tensions between the English and French crowns.
