The request of the Scottish Regent, Mary of Guise, for help to fight the English was answered by the arrival of an army of several thousand French. The assistance came on condition that her daughter Mary Stuart should marry the French Dauphin, Francis.

A group of Scottish Lords signed a covenant promising to support the advancement 'the most blessed Word of God' and to push forward the Reformation in Scotland. This was a move against what they saw as the threat from France which came from the marriage of Mary, Queen of Scots to the French Dauphin. They called themselves the Lords of the Congregation.

An agreement was reached between the Scottish commissioners and the French king Henry II for the marriage of Mary, Queen of Scots and Francis, the Dauphin of France. The terms of the agreement allowed the Scots to maintain their traditional rights and would become united with France when Francis became King of France. It was also agreed that if Mary died without having children the Scottish throne would go to the Earl of Arran.

Mary, Queen of Scots married Francis, the Dauphin of France. A secret marriage agreement was signed by Mary giving control of Scotland to France if she died without having children.

Henry II, the French king, was accidentally injured during a tournament celebrating a wedding. He was taking part in a joust and the tip of a lance went into his eye. Infection set it and he died a short time afterwards. Henry was succeeded by his son Francis II, the husband of Mary Stuart.

Francis II was crowned King of France at Rheims Cathedral. The ceremony was subdued because of the untimely death of his father.

Francis II, King of France died at the age of sixteen from an abscess in his brain. He had suffered from poor health throughout his life.
