Baron Coleville

Walter de Colville of Castle Bytham in Lincolnshire[1] was summoned in 1264 to a parliament convened by Simon de Montfort, who held King Henry III of England captive.

Walter was captured by Prince Edward later that year and was forced to redeem his confiscated lands.

While participation in this rebel parliament is not considered to have created a hereditary peerage, Walter's great-grandson, Robert de Coleville, sat in Parliament from 1331 and later received a royal writ that by modern practice is viewed to have made him Lord Coleville.

The title became extinct on the death of his son Robert at the age of 6 in 1370, his heirs being the descendants of two sisters of his grandfather, granddaughters of the Walter summoned by Montfort.

It was originally owned by the Northumbrian earl Morcar, who tried to stop William the Conqueror around the time of the Norman invasions of 1066.
