Lambert Simnel (c.1475-c.1535) was a pretender to the crown of Henry VII . Because of a remarkable resemblance, was put forward by Yorkists as Edward, earl of Warwick, nephew of the deposed Richard III and therefore the rightful heir of that king. He is believed to have been the son of an Oxford artisan.
He was crowned king of England as Edward VI in Dublin in May 1487, and was the nominal head of a considerable force that landed in England a month later. The king met him in battle at Stoke near Newark on 16 June, and was victorious. In an act of clemency (or in a burst of humour not often seen in that era) Henry pardoned him, but put him to work in the palace kitchens as a scullery lad. He lived in obscurity for a further 48 years or so. The real leaders of the plot were not so lucky.
The Wars of the Roses are considered to have ended with the battle of Stoke..
