This Day in History: 1265-10-25
On 25th October 1265, the Duchy of Lancaster, of which Pontefract Castle is now a part, was formally created. The inheritance was created in this year by Henry III for his youngest son, Edmund. The original grant was made from lands forfeited by Simon de Montfort, Earl of Leicester (1265) and those forfeited by Robert Ferrers, Earl of Derby were later added in 1266 (arising from the Barons’ War). These lands are still held by the Duchy of Lancaster today.
In 1267 further lands were added to the inheritance namely the Honour and County of Lancaster, and Edmund was created as the first Earl of Lancaster. The inheritance became known as the Duchy of Lancaster. Although the Duchy of Lancaster name itself stems from 1267, the inheritance of lands go back to 1265. Pontefract Castle was incorporated into the Duchy on the death of Henry de Lacy in 1311.
