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
The Tudor period is the period between 1485 and 1603 in England and Wales and includes the Elizabethan period during the reign of Elizabeth I until 1603. The Tudor period coincides with the dynasty of the House of Tudor in England whose first monarch was Henry VII (14571509). In terms of the entire span, the historian John Guy (1988) argues that "England was economically healthier, more expansive, and more optimistic under the Tudors" than at any time in a thousand years.
