James II was King of Scots from 1437 until his death in 1460. The eldest surviving son of James I of Scotland, he succeeded to the Scottish throne at the age of six, following the assassination of his father. The first Scottish monarch not to be crowned at Scone, James II's coronation took place at Holyrood Abbey in March 1437. After a reign characterised by struggles to maintain control of his kingdom, he was killed by an exploding cannon at Roxburgh Castle in 1460.
