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.
Artists of the Tudor court
The Tudor period was one of unusual isolation from European trends for England. At the start the Wars of the Roses had greatly disrupted artistic activity, which apart from architecture had reached a very low ebb by 1485. The Yorkist dynasty overthrown by the Tudors had been very close to their Burgundian allies, and English diplomats had their portraits painted by the finest Early Netherlandish painters - Edward Grimshaw by Petrus Christus and Sir John Donne by Hans Memling (both National Gallery, London). However these were both painted abroad. In the Tudor period foreign artists were recruited and often welcomed lavishly by the English court, as they were in other artistically marginal parts of Europe like Spain or Naples. The Netherlandish painters remained predominant, though French influence was also important on both Lucas Horenbout and Nicholas Hilliard, respectively the founder and the greatest exponent of the distinctively English tradition of the portrait miniature.
