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.
History of England
In all, the Tudor period is seen as a decisive one which set up many important questions which would have to be answered in the next century and during the English Civil War. These were questions of the relative power of the monarch and Parliament and to what extent one should control the other. Some historians think that Thomas Cromwell affected a "Tudor Revolution" in government, and it is certain that Parliament became more important during his chancellorship. Other historians argue that the "Tudor Revolution" extended to the end of Elizabeth's reign, when the work was all consolidated. Although the Privy Council declined after Elizabeth's death, it was very effective while she was alive.
