Richard III is a history play by William Shakespeare, believed to have been written in approximately 1591. The play is an unflattering depiction of the short reign of Richard III of England. While generally classified as a history, as grouped in the First Folio, the play is sometimes called a tragedy (as in the first quarto). It picks up the story from Henry VI, Part 3 and concludes the historical series that stretches back to Richard II.

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.

Vicious battles, powerful monarchs, and royal intrigue abound in this “gripping, complex, and sensational” (Hilary Mantel) true story of the War of the Roses—a struggle among three brothers, two of whom became kings, and the inspiration for Shakespeare’s renowned play, Richard III. In 15th-century England, two royal families, the House of York and the House of Lancaster, fought a bitter, decades-long civil war for the English throne. As their symbols were a red rose for Lancaster and a white rose for York, the conflict became known as the Wars of the Roses. During this time, the house of York came to dominate England. At its heart were three charismatic brothers—King Edward IV, and his two younger siblings George and Richard—who became the figureheads of a spectacular ruling dynasty. Together, they looked invincible. But with Edward’s ascendancy the brothers began to turn on one another, unleashing a catastrophic chain of rebellion, vendetta, fratricide, usurpation, and regicide. The brutal end came at Bosworth Field in 1485, with the death of the youngest, then Richard III, at the hands of a new usurper, Henry Tudor, later Henry VII, progenitor of the Tudor line of monarchs. Fascinating, dramatic, and filled with vivid historical detail, The Brothers York is a brilliant account of a conflict that fractured England for a generation. Riven by internal rivalries, jealousy, and infighting, the three York brothers failed to sustain their power and instead self-destructed. It is a rich and bloody tale as gripping as any historical fiction.

The Last Days of Richard III contains a new and uniquely detailed exploration of Richard's last 150 days. By deliberately avoiding the hindsight knowledge that he will lose the Battle of Bosworth Field, we discover a new Richard: no passive victim, awaiting defeat and death, but a king actively pursuing his own agenda. It also re-examines the aftermath of Bosworth: the treatment of Richard's body; his burial; and the construction of his tomb. And there is the fascinating story of why, and how, Richard III's family tree was traced until a relative was found, alive and well, in Canada. Now, with the discovery of Richard's skeleton at the Greyfrairs Priory in Leicester, England, John Ashdown-Hill explains how his book inspired the dig and completes Richard III's fascinating story, giving details of how Richard died, and how the DNA link to a living relative of the king allowed the royal body to be identified.
