DUPLICATE: AFN> Listed in Ancestral File as Gilbert De Clare (Earl Of Gloucester And Hertford) - AFN: 4TNG-DKF.
KINSHIP: Son and heir by 2nd wife.
BIRTH: Date> 2 Sep 1243 (Ann.Theokes.fo 43).
TITLES: 3rd Earl of Gloucester; 6th Earl of Hertford; Lord of Clare, Tonbridge, Cardigan, and Glamorgan by tenure.
PROPERTY: Had livery of the Castles of Cardiff, Newport, and Llantrissent, 3 Aug 1263 (Pat.47 Hen.3.p 1.m 4).
POLITICS: Though still under age, he joined Montfort and the Barons in opposition to the King, and was one of the chief of the confederates who marched with him to Lewes.
MILITARY: Knighted with his brother Thomas by Simon de Montfort, Earl of Leicester, before the Battle of Lewes, 14 May 1264 (Ann.Wigorn.fo 129).
MILITARY: Appointments> Commanded the second brigade of the Baronial Army in the Battle of Lewes (Ann.Wigorn.fo 129).
POLITICS: Immediately after the Battle of Lewes, he was joined with Montfort and the Bishop of Chichester in the virtual government of the whole Kingdom (Pat.48 Hen.3.p 1.m 10), with power to nominate 9 men, by whose counsel affairs should be ruled.
PROPERTY: Obtained a grant for himself, of the Castle of Pembroke, and all the other lands of William de Valence the King's brother, 6 Jun 1264 (Pat.48 Hen.3.p 1.m 12); of all the lands in England, of John de Warrenne, Earl of Surrey, except the Castles of Reigate and Lewes, 20 Jun 1264 (Pat.48 Hen.3.p 1.m 11); of all the Castles and lands of Peter de Savoy, the Queen's uncle, 10 Jul 1264 (Pat.48 Hen.3.p 1.m 8).
POLITICS: In less than a twelve-month he had quarrelled with Montfort, who, attempting to assume the entire rule of the Kingdom upon himself, by his imperious and rapacious conduct, alienated the sympathy of many of his former allies. By 20 May 1265, Monfort was issuing proclamations denying the rumour of a breach between them (Pat.49 Hen.3.m 15). But Montfort's dictatorial conduct in dealing with others of his former friends, caused Gloucester to distrust him.
POLITICS: A tournament at Northampton was proclaimed, but Gloucester, fearing a snare, hastened to the Welsh Marches, where his influence was enormous as chief of the Marcher Lords. Here he had a conference with Roger de Mortimer, who was the most prominent Royalist in the Marches, and between them, they effected the escape of Prince Edward, who had been taken prisoner at Lewes. This being successfully accomplished, 28 May 1265, the whole of the Welsh Marches rallied to their standard.
MILITARY: Appointments> Commanded the second brigade of the Royal Army at the Battle of Evesham, 4 Aug 1265.
PUNISHMENT: Pardon> Had a formal pardon for his earlier acts of rebellion, 9 Oct 1265; had a grant of the Castle of Abergavenny during the minority of the heir of Humphrey de Bohun the younger, 25 Oct 1265 (Pat.49 Hen.3.m 5 & 3).
PROPERTY: Obtained a grant of all the lands of John Fitz John, 24 Jan 1266 (Pat.50 Hen.3.m 33).
POLITICS: After the final overthrow of the rebels in the Isle of Ely, 1267, he seems to have attempted to assume the conduct of the affairs of the Kingdom in his own hands. He demanded that the rebels, many of whom were his former friends, should have restoration of their forfeited estates (Chron.Dunst.394/5), and upon this request being refused, he raised an army, and marched on London.
MILITARY: Battles and Wars> He entered the City of London on 9 Apr 1267 with a few of his followers; but no ssoner was he in possession, than he admitted parties of the rebels, and siezed the Tower. But on the approach of the King, not considering himself strong enough to stand a siege, he engaged Philip Basset and others to make his peace, 15 Jun 1267, and procured a free pardon for himself and his followers (Pat.51 Hen.3.m 15).
OFFICE: On the death of King Henry III, he was one of the Governors of the Kingdom till the return of Edward I from the Holy Land.
