As they were all immediate vassals of the crown by military tenure, they were, by the principles of the feudal law, equally entitled with the greatest barons to a seat in the national or general councils; and this right, though regarded as a privilege which the owners would not entirely relinquish, was also considered as a burden which they desired to be subjected to on extraordinary occasions only.

Hence it was provided in the charter of King John, that, while the great barons were summoned to the national council by a particular writ, the small barons, under which appellation the knights were also comprehended, should only be called by a general summons of the sheriff.

The distinction between great and small barons, like that between rich and poor, was not exactly defined; but, agreeably to the inaccurate genius of that age, and to the simplicity of ancient government, was left very much to be determined by the discretion of the king and his ministers.

It was usual for the prince to require, by a particular summons, the attendance of a baron in one parliament, and to neglect him in future parliaments;[*] nor was this uncertainty ever complained of as an injury.

He attended when required: he was better pleased on other occasions to be exempted from the burden: and as he was acknowledged to be of the same order with the greatest barons, it gave them no surprise to see him take his seat in the great council, whether he appeared of his own accord, or by a particular summons from the king.
