prince Philip, son of her mother's nephew Charles V, Holy Roman Emperor. The prospect of a marriage alliance with Spain proved unpopular with the English people, who were worried that Spain would use England as a satellite, involving England in wars without the popular support of the people. Popular discontent grew; a Protestant courtier, Thomas Wyatt the younger, led a rebellion against Mary aiming to depose and replace her with her half-sister Elizabeth. The plot was discovered, and Wyatt's supporters were hunted down and killed. Wyatt himself was tortured, in the hope that he would give evidence that Elizabeth was involved so that Mary could have her executed for treason. Wyatt never implicated Elizabeth, and he was beheaded. Elizabeth spent her time between different prisons, including the Tower of London. Mary married Philip at Winchester Cathedral, on 25 July 1554, and he thereby became king jure uxoris until her death. Philip found her unattractive, and only spent a minimal amount of time with her. Despite Mary believing she was pregnant numerous times during her five-year reign, she never bore children. Devastated that she rarely saw her husband, and anxious that she was not bearing an heir to Catholic England, Mary became bitter. In her determination to restore England to the Catholic faith and to secure her throne from Protestant threats, she had 200–300 Protestants burnt at the stake in the Marian Persecutions between 1555 and 1558. Protestants came to hate her as "Bloody Mary." Charles Dickens stated that "as bloody Queen Mary this woman has become famous, and as Bloody Queen Mary she will ever be remembered with horror and detestation" Mary's dream of a new, Catholic Habsburg line was finished, and her popularity further declined when she lost Calais — the last English area on French soil — to Francis, Duke of Guise, on 7 January 1558. Mary's reign, however, introduced a new coining system that would be used until the 18th century, and her marriage to Philip II created new trade routes for England. Mary's government took a number of steps towards reversing the inflation, budgetary deficits, poverty, and trade crisis of her kingdom. She explored the commercial potential of Russian, African, and Baltic markets, revised the customs system, worked to counter the currency debasements of her predecessors, amalgamated several revenue courts, and strengthened the governing authority of the middling and larger towns.
