Richard III (2 October 1452 - 22 August 1485) was King of England from 1483 until his death in 1485 in the Battle of Bosworth Field. He was the last king of the House of York and the last of the Plantagenet dynasty. His defeat at Bosworth Field, the last decisive battle of the Wars of the Roses, marked the end of the Middle Ages in England. He is the subject of the fictional historical play Richard III by William Shakespeare. In 2012, an archaeological excavation was conducted on a city council car park using ground-penetrating radar on the site once occupied by Greyfriars, Leicester. The University of Leicester confirmed on 4 February 2013 that the skeleton found in the excavation is that of Richard III, based on the results of radiocarbon dating, a comparison with contemporary reports of his appearance, and a comparison of his mitochondrial DNA with that of two matrilineal descendants of Richard III's eldest sister, Anne of York.
