The Yorkists were supporters of the House of York, a prominent faction during the Wars of the Roses, a series of civil wars in England from the 15th century. They were primarily in conflict with the Lancastrians, who supported the rival House of Lancaster. The Yorkists aimed to claim the English throne, believing they had a legitimate right to rule through their lineage. Key figures among the Yorkists included Edward IV, who became king, and Richard III, his brother. The Yorkist emblem was a white rose, symbolizing their cause. Their struggle for power significantly shaped English history and led to the eventual rise of the Tudor dynasty.
