On 31 Oct 1266 the Dictum of Kenilworth was issued. The Dictum was a peace agreement between Henry III King England 1207-1272 (59) and the rebels who were besieged in the impregnable Kenilworth Castle, Kenilworth, Warwickshire.
Those appointed to the committee by Parliament included:Walter Branscombe Bishop Exeter 1220-1280 (46)
Walter Giffard Archbishop York 1225-1279 (41)
Nicholas Ely Bishop Worcester, Bishop Winchester -1280
Gilbert Clare 8th Earl Gloucester, 7th Earl Hertford -1314
Humphrey Bohun 2nd Earl Hereford, 1st Earl Essex 1204-1275 (62)

Alan Zouche 1203-1270 (63)
Roger Somery 2nd Baron Dudley 1190-1273 (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 1239-1279 (27) and Henry Hastings 1235-1269 (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.

Surrender of Kenilworth

On 12 Sep 1266 the garrison at Kenilworth Castle, Kenilworth, Warwickshire surrendered.

Statute of Marlborough

Before 16 Nov 1267 the Statute of Marlborough revised the Dictum of Kenilworth insofar as those fined were restored to their lands so that they could pay their fines .
