Descended from the Stuart kings of Scotland and from Henry VII of England, related to the powerful family of Guise in France, Mary had been brought up at the French court and married to the short-lived French king, Francis II. Upon the death of the latter she returned in 1561 to Scotland, a young woman of but eighteen years, only to find that the government had fallen victim to the prevalent factional fights among the Scotch nobles and that in the preceding year the parliament had solemnly adopted a Calvinistic form of Protestantism. By means of tact and mildness, however, Mary won the respect of the nobles and the admiration of the people, until a series of marital troubles and blunders--her marriage with a worthless cousin, Henry Darnley, and then her scandalous marriage with Darnley's profligate murderer, the earl of Bothwell--alienated her people from her and drove her into exile. She abdicated the throne of Scotland in favor of her infant son, James VI, who was reared a Protestant and subsequently became King James I of England, and she then (1568) threw herself upon the mercy of Elizabeth. She thought she would find in England a haven of refuge; instead she found there a prison. For the score of years during which she remained Elizabeth's prisoner, Mary Stuart was the object of many plots and conspiracies against the existing governments of both Scotland and England. In every such scheme were to be found the machinations and money of the Spanish king. In fact, as time went on, it seemed to a growing section of the English people as though the cause of Elizabeth was bound up with Protestantism and with national independence and prosperity just as certainly as the success of Mary would lead to the triumph of Catholicism, the political supremacy of Spain, and the commercial ruin of England. It was under these circumstances that Mary's fate was sealed. Because of a political situation over which she had slight control, the ex-queen of Scotland was beheaded by Elizabeth's orders in 1587.
