Joan Beaufort was Queen of Scotland from 1424 to 1437 as the spouse of King James I of Scotland. During part of the minority of her son James II, she served as the regent of Scotland.

James I was King of Scots from 1406 until his assassination in 1437. The youngest of three sons, he was born in Dunfermline Abbey to King Robert III and Annabella Drummond. His older brother David, Duke of Rothesay, died under suspicious circumstances during detention by their uncle, Robert, Duke of Albany. James' other brother, Robert, died young. Fears surrounding James's safety grew through the winter of 1405/06 and plans were made to send him to France. In February 1406, James was forced to take refuge in the castle of the Bass Rock in the Firth of Forth after his escort was attacked by supporters of Archibald, 4th Earl of Douglas. He remained at the castle until mid-March, when he boarded a vessel bound for France. On 22 March, English pirates captured the ship and delivered the prince to Henry IV of England. The ailing Robert III died on 4 April and the 11-year-old James, now the uncrowned King of Scots, would not regain his freedom for another eighteen years.
