James V died in 1542, leaving the infant Mary, Queen of Scots as his heir, with the prospect of a long minority. At the beginning of the Mary's reign, the Scottish political nation was divided between a pro-French faction, led by Cardinal Beaton and by the Queen's mother, Mary of Guise; and a pro-English faction, headed by Mary's prospective heir James Hamilton, Earl of Arran. Initially Arran became Regent, backed by the small "evangelical party" at court, who favoured religious reform. The Parliamentary Act of 1543 removed the prohibition against reading the Bible in the vernacular. A planned marriage between Mary and Edward, the son of Henry VIII of England, which had been agreed under the Treaty of Greenwich (1543), led to a backlash in Scotland and a coup led by Cardinal Beaton. He repudiated the reforming policies, and all consideration of an English marriage for the Queen, angering the English. They invaded in order to enforce the match, an action later known as the "rough wooing", which devastated south-east Scotland.
