History of England
With Henry VII's accession to the throne in 1485, the Wars of the Roses came to an end, and Tudors would continue to rule England for 118 years. Traditionally, the Battle of Bosworth Field is considered to mark the end of the Middle Ages in England, although Henry did not introduce any new concept of monarchy, and for most of his reign his hold on power was tenuous. He claimed the throne by conquest and God's judgement in battle. Parliament quickly recognized him as king, but the Yorkists were far from defeated. Nonetheless, he married Edward IV's eldest daughter Elizabeth in January 1486, thereby uniting the houses of York and Lancaster.
House of Tudor
Mary's dream of a new, Catholic Habsburg line was finished, and her popularity further declined when she lost the last English area on French soil, Calais, 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. Mary also welcomed the first Russian ambassador to England, creating relations between England and Russia for the first time. Had she lived a little longer, Catholicism, which she worked so hard to restore into the realm might have taken deeper roots than it did. However, her actions in pursuit of this goal arguably spurred on the Protestant cause, through the many martyrs she made. Mary died on 17 November 1558 at the relatively young age of 42.
