31 Oct 1266 Dictum of Kenilworth
On 31 Oct 1266 the Dictum of Kenilworth was issued. The Dictum was a peace agreement between Henry III King England (59) and the rebels who were besieged in the impregnable Kenilworth Castle. Those appointed to the committee by Parliament included: Bishops Walter Branscombe Bishop Exeter, Walter Giffard Archbishop York, Nicholas Unknown Bishop Worcester, Bishop Winchester and Richard Carew Bishop Bath and Wells, Earls Gilbert Clare 8th Earl Gloucester, Earl Hertford and Humphrey Bohun 2nd Earl Hereford, 1st Earl Essex (62) and Barons Philip Basset, John Balliol (58) , Robert Walerand, Alan Zouche (63) , Roger Somery 2nd Baron Dudley (76) and Warin Bassingbourne. The committee were given until All Saints Day, 01 Nov 1266, to draft and agreement. The primary purpose of the Dictum was to restore Royal authority repudiating the Provisions of Oxford, confirming the Magna Carta and Charter of the Forest. Rebels were fined five times their annual income. Rebel commanders Robert Ferrers 6th Earl Derby (27) and Henry Hastings (31) were fined seven times their annual income. The Dictum, however, required the rebels to pay their fines before being restored to their lands; something of a Catch-22 since if they weren't restored to their lands they would have no income to pay the fine.
