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.
Tudor period
Historian Geoffrey Elton argued that Thomas Cromwell, who was Henry VIII's chief minister from 1532 to 1540, not only removed control of the Church of England from the hands of the Pope, but transformed England with an unprecedented modern, bureaucratic government. Cromwell (1485–1540) replaced medieval government-as-household-management. Cromwell introduced reforms into the administration that delineated the King's household from the state and created a modern administration. He injected Tudor power into the darker corners of the realm and radically altered the role of the Parliament of England. This transition happened in the 1530s, Elton argued, and must be regarded as part of a planned revolution. Elton's point was that before Cromwell the realm could be viewed as the King's private estate writ large, where most administration was done by the King's household servants rather than separate state offices. By masterminding these reforms, Cromwell laid the foundations of England's future stability and success. Cromwell's luck ran out when he picked the wrong bride for the King; he was beheaded for treason, More recently historians have emphasised that the king and others played powerful roles as well.
