Roger Mortimer, 1st Baron Wigmore

Roger Mortimer, 1st Baron Mortimer, of Wigmore (1231 – 30 October 1282), was a famous and honoured knight from Wigmore Castle in Herefordshire. He was a loyal ally of King Henry III of England. He was at times an enemy, at times an ally, of Llywelyn ap Gruffudd, Prince of Wales.

Born in 1231, Roger was the son of Ralph de Mortimer and his Welsh wife, Princess Gwladys Ddu, daughter of Llywelyn ab Iorwerth and Joan Plantagenet, daughter of John "Lackland", King of England.

In 1256 Roger went to war with Llywelyn ap Gruffudd when the latter invaded his lordship of Gwrtheyrnion or Rhayader. This war would continue intermittently until the deaths of both Roger and Llywelyn in 1282. They were both grandsons of Llywelyn ab Iorwerth.

Mortimer fought for the King against the rebel Simon de Montfort, 6th Earl of Leicester, and almost lost his life in 1264 at the Battle of Lewes fighting Montfort's men. In 1265 Mortimer's wife, Maud de Braose helped rescue Prince Edward; and Mortimer and the Prince made an alliance against de Montfort.

In August 1265, de Montfort's army was surrounded by the River Avon on three sides, and Prince Edward's army on the fourth. Mortimer had sent his men to block the only possible escape route, at the Bengeworth bridge. The Battle of Evesham began in earnest. A storm roared above the battle field. Montfort's Welsh soldiers broke and ran for the bridge, where they were slaughtered by Mortimer's men. Mortimer himself killed Hugh Despencer and Montfort, and crushed Montfort's army. Mortimer was awarded Montfort's severed head and other parts of his anatomy, which he sent home to Wigmore Castle as a gift for his wife, Lady Mortimer.
