Mary Queen of Scots now had an heir, but she needed a spare in case Prince James died before becoming king of Scotland. So she would have to marry again. There was the king of France, Charles IX . He was the younger brother of Francis II of France, Mary's first husband. Charles was only sixteen years old, born 27 June 1550. Mary was twenty-four years old, born 8 December 1542. Mary knew Charles when she lived in France.
Archduke Charles II of Austria, born 3 June 1540, was another possibility. Then there was James Hepburn, Earl of Bothwell, born 1535. He had met Mary in the autumn of 1560 when he was in the party of nobles who had travelled to France to bring her home to Scotland. He had the qualities Mary found attractive in men, and was emotionally and sexually attracted to him. He was her warrior hero. Though a Protestant he was anti-English. In the months after Rizzio's murder, Mary had relied on him.
But Bothwell was married. At the end of February 1566, Bothwell had married Jean Gordon, sister of the Earl of Huntly. Jean was in love with Alexander Ogilivie, who was married to Mary Beaton. Huntly was pressing his sister to end her marriage to Bothwell, and she was giving the matter serious consideration. On 21 March she began divorce proceedings against her husband on the ground of his adultery with Bessie Crawford, a sewing maid, more than a year before.
Many Scottish nobles were Bothwell's enemies, among them James Stewart, Earl of Moray, Mary's illegitimate half brother. Sir James Melville, Mary's chief adviser, had no time for Bothwell and did not want Mary to marry him. He advised Mary to do what was reasonable and not give way to the passions of the mind.
Mary was emotional, impulsive, impatient, with an adventurous spirit. Her nature was not naturally cautious or thoughtful. Mary married Bothwell at four in the morning of Thursday 15 May 1567, in a Protestant ceremony in the great hall of Holyroodhouse. He and Jean Gordon, having been granted a divorce.
Marriage to Charles IX or to the Archduke Charles would have been politically and diplomatically better, but Mary was in love with Bothwell.
