James Douglas, 4th Earl of Morton, Scottish soldier and politician, Lord Chancellor of Scotland (born 1525)

James Douglas, 4th Earl of Morton was a Scottish nobleman. He played a leading role in the murders of Queen Mary's confidant, David Rizzio, and king consort Henry Darnley. He was the last of the four regents of Scotland during the minority of James VI. He was in some ways the most successful of the four since he won the civil war that had been dragging on with the supporters of the exiled Mary, Queen of Scots. However, he came to an unfortunate end, executed by means of the Maiden, a predecessor of the guillotine.

The Lord Chancellor of Scotland, formally titled Lord High Chancellor, was an Officer of State in the Kingdom of Scotland. The Lord Chancellor was the principal Great Officer of State, the presiding officer of the Parliament of Scotland, the Keeper of the Great Seal, the presiding officer of the Privy Council, and a judge of the College of Justice.
