Meanwhile, the king, less shocked with the illegal violence which had been imposed upon him, than unhappy in the absence of his minion, employed every expedient to soften the opposition of the barons to his return; as if success in that point were the chief object of his government.

The high office of hereditary steward was conferred on Lancaster: his father-in-law, the earl of Lincoln, was bought off by other concessions: Earl Warrenne was also mollified by civilities, grants, or promises: the insolence of Gavaston, being no longer before men's eyes, was less the object of general indignation; and Edward, deeming matters sufficiently prepared for his purpose, applied to the court of Rome, and obtained for Gavaston a dispensation from that oath which the barons had compelled him to take, that he would forever abjure the realm.[*] He went down to Chester to receive him on his first landing from Ireland; flew into his arms with transports of joy; and having obtained the formal consent of the barons in parliament to his reestablishment, set no longer any bounds to his extravagant fondness and affection.

Gavaston himself, forgetting his past misfortunes, and blind to their causes, resumed the same ostentation and insolence, and became more than ever the object of general detestation among the nobility.
The barons first discovered their animosity by absenting themselves from parliament; and finding that this expedient had not been successful, they began to think of employing sharper and more effectual remedies.
Though there had scarcely been any national ground of complaint, except some dissipation of the public treasure: though all the acts of mal-administration objected to the king and his favorite, seemed of a nature more proper to excite heart-burnings in a ball or assembly, than commotions in a great kingdom: yet such was the situation of the times, that the barons were determined, and were able, to make them the reasons of a total alteration in the constitution and civil government.

Having come to parliament, in defiance of the laws and the king's prohibition, with a numerous retinue of armed followers, they found themselves entirely masters; and they presented a petition which was equivalent to a command, requiring Edward to devolve on a chosen junto the whole authority, both of the crown and of the parliament.
