The Battle of Tinchebray took place on 28 September 1106, in Tinchebray, Normandy, between an invading force led by King Henry I of England, and the Norman army of his elder brother Robert Curthose, the Duke of Normandy. Henry's knights won a decisive victory: they captured Robert, and Henry imprisoned him in England and then in Wales until Robert's death in 1134.

Henry I, also known as Henry Beauclerc, was King of England from 1100 to his death in 1135. He was the fourth son of William the Conqueror and was educated in Latin and the liberal arts. On William's death in 1087, Henry's elder brothers Robert Curthose and William Rufus inherited Normandy and England, respectively, but Henry was left landless. He purchased the County of Cotentin in western Normandy from Robert, but his brothers deposed him in 1091. He gradually rebuilt his power base in the Cotentin and allied himself with William Rufus against Robert.
