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.
Mary I of England
Mary I (18 February 1516 – 17 November 1558), also known as Mary Tudor, was the Queen of England and Ireland from July 1553 until her death. She is best known for her aggressive attempt to reverse the English Reformation, which had begun during the reign of her father, Henry VIII. The executions that marked her pursuit of the restoration of Roman Catholicism in England and Ireland led to her denunciation as "Bloody Mary" by her Protestant opponents.
