For the seven turbulent years of Mary's stay in Scotland, she was a grievous thorn in the side of Elizabeth. She was always laying claim to be acknowledged as heiress to the English crown, and her demand was secretly approved by the surviving Romanists to the south of the Tweed. Elizabeth replied by intriguing with the Protestant nobles of Scotland, and stirred up as much trouble as she could for her cousin, while outwardly professing the greatest love and esteem for her. The results of their machinations against each other were still uncertain, when Mary spoilt her own game by twice allowing her passion to overrule her judgment. She was fascinated by the handsome person of her first-cousin, Henry Lord Darnley,[34] and most unwisely married him, and made him king-consort. Darnley was a vicious, ill-conditioned young man, and soon made himself unbearable to his wife, by striving to get the royal power into his hands, and at the same time treating her with gross cruelty and neglect. His crowning offence was causing the assassination of Mary's private secretary, Rizzio, in her actual presence, under circumstances of the greatest brutality. After this, Mary completely lost her head. She lent her sanction to a plot for her husband's murder, framed by the Earl of Bothwell, a great lord of the Border. Bothwell slew the young king and blew up his residence with gunpowder, but disavowed the deed, and induced the queen to have him declared guiltless after a mock trial. Mary was well rid of her husband, and, her complicity in the plot not having been proved, she might have escaped the consequences of her crime but for a second fit of infatuation. She had become violently enamoured of the murderer Bothwell, and suffered him to carry her off to the castle of Dunbar, and there to marry her. No one now doubted her complicity in Darnley's murder, and the whole kingdom rose against her in righteous indignation. The army which Bothwell raised in her defence refused to strike a blow, and melted away when faced by the levies of the Protestant lords. The queen herself fell into their hands, was forced to abdicate, and was condemned to lifelong prison in Lochleven Castle. In Mary's place, her young son by Darnley, James VI., was proclaimed as king, the regency being given by the Parliament to James, Earl of Murray, an illegitimate son of James V. (June, 1567). Queen Mary being thus imprisoned and discredited, Elizabeth thought that her troubles on the side of Scotland were over, and closely allied herself with the Regent Murray. But the struggle was not yet ended. The Romanist party in Scotland saw that the new Protestant rulers of the country would crush their faith, and determined on a desperate rising in favour of their old religion and their old sovereign.
