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 Crown
Its date of manufacture is unknown, but Henry VII or his son and successor Henry VIII probably commissioned the crown, first documented in writing in a 1521 inventory of Henry VIII's jewels, naming the crown as "the king's crown of gold". More elaborate than its medieval predecessor, it originally had two arches, five crosses pattée and five fleurs-de-lis, and was decorated with emeralds, sapphires, rubies, pearls, diamonds and, at one time, the Black Prince's Ruby (a large spinel). The centre petals of the fleurs-de-lis had images of Christ, the Virgin Mary and St George, in an effort by Henry VIII to secure his position as head of the new Church of England. The crown was mentioned again in 1532, 1550, 1574 and 1597.
