supports: Edward of Middleham , Prince of Wales , Earl of Chester , Duke of Cornwall , 1st Earl of Salisbury ( December 1473 -- 9 April 1484 ) , was the only child of King Richard III of England and his queen consort , Anne Neville . He was Richard 's only legitimate child and died aged ten . In 1485 Richard III was killed at the Battle of Bosworth and the throne of England passed to the Lancastrian claimant , Henry Tudor , a descendant of Edward III of England through his mother , Lady Margaret Beaufort . The Battle of Bosworth Field (or Battle of Bosworth) was the last significant battle of the Wars of the Roses, the civil war between the Houses of Lancaster and York that raged across England in the latter half of the 15th century. Fought on 22 August 1485, the battle was won by the Lancastrians. Their leader Henry Tudor, Earl of Richmond, by his victory became the first English monarch of the Tudor dynasty. His opponent, Richard III, the last king of the House of York, was killed in the battle. Historians consider Bosworth Field to mark the end of the Plantagenet dynasty, making it a defining moment of English and Welsh history. The House of York was a cadet branch of the English royal House of Plantagenet. Three of its members became Kings of England in the late 15th century. The House of York was descended in the male line from Edmund of Langley, 1st Duke of York, the fourth surviving son of Edward III, but also represented Edward's senior line, being cognatic descendants of Lionel, Duke of Clarence, Edward III's second surviving son. It is based on these descents that they claimed the English crown. Compared with the House of Lancaster, it had a senior claim to the throne of England according to cognatic primogeniture but junior claim according to the agnatic primogeniture. The reign of this dynasty ended with the death of Richard III of England in 1485. It became extinct in the male line with the death of Edward Plantagenet, 17th Earl of Warwick in 1499. Llywelyn ap Gruffudd (c. 1223  11 December 1282), sometimes written as Llywelyn ap Gruffydd, also known as Llywelyn the Last, or, in Welsh, Llywelyn Ein Llyw Olaf, was Prince of Wales (Latin; "Princeps Wallie", Welsh; "Tywysog Cymru") from 1258 until his death at Cilmeri in 1282. The son of Gruffudd ap Llywelyn Fawr and grandson of Llywelyn the Great, he was the last sovereign prince of Wales before its conquest by Edward I of England. Prince of Wales was a title granted to princes born in Wales from the 12th century onwards; the term replaced the use of the word "king". One of the last Welsh princes, Llywelyn ap Gruffudd, was killed in battle in 1282 by Edward I, King of England, whose son Edward, born in Caernarfon Castle, was invested as Prince of Wales: the first English person to claim the title.  As a means of recording the passage of time, the 12th century is the period from 1101 to 1200 in accordance with the Julian calendar in the Common Era. In the history of European culture, this period is considered part of the High Middle Ages and is sometimes called the Age of the Cistercians. In Song dynasty China an invasion by Jurchens caused a political schism of north and south. The Khmer Empire of Cambodia flourished during this century, while the Fatimids of Egypt were overtaken by the Ayyubid dynasty. Richard III (2 October 1452  22 August 1485) was King of England from 1483 until his death in 1485, at the age of 32, 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 historical play "Richard III" by William Shakespeare.
