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 conquest of Ireland
The Tudor conquest (or reconquest) of Ireland took place under the Tudor dynasty, which held the Kingdom of England during the 16th century. Following a failed rebellion against the crown by Silken Thomas, the Earl of Kildare, in the 1530s, Henry VIII was declared King of Ireland in 1542 by statute of the Parliament of Ireland, with the aim of restoring such central authority as had been lost throughout the country during the previous two centuries.
