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.
Bernard Stewart, 4th Lord of Aubigny
The Lord of Aubigny was also the medium of communication with the section of Scottish lords who favoured Henry Tudor, Earl of Richmond in his rebellion against his distant cousin King Richard III of England. Henry was still an exile living in France along with the chief supporters of the House of Lancaster, the experienced John de Vere, 13th Earl of Oxford and Henry's uncle Jasper Tudor, 1st Duke of Bedford. They relied heavily on the French king to finance the army and to be able to provide foot soldiers capable of fighting. In 1485 Bernard Stewart was chosen to command the French troops that accompanied the invasion and helped the Earl of Richmond become King Henry VII of England at the Battle of Bosworth Field establishing the Tudor Dynasty.
