The Battle of Bosworth or Bosworth Field was an important battle during the Wars of the Roses in 15th century England. It was fought on 22 August 1485 between the Yorkist King Richard III, the last of the Plantagenet dynasty, and the Lancastrian Henry Tudor, who wanted to become king. It ended in the defeat and death of Richard and the beginning of the Tudor dynasty. Historically, the battle is thought to have marked the end of the Wars of the Roses, although smaller battles were fought in the years that followed as Yorkists unsuccessfully tried to become king again.
