13. =William's Great Councils.=--Though William was himself the true ruler of England, he kept up the practice of his predecessors in summoning the Witenagemot from time to time. In his days, however, the name of the Witenagemot was changed into that of the Great Council, and, to a slight extent, it changed its nature with its name. The members of the Witenagemot had attended because they were officially connected with the king, being ealdormen or bishops or thegns serving in some way under him. Members of the Great Council attended because they held land in chief from the king. The difference, however, was greater in appearance than in reality. No doubt men who held very small estates in chief might, if they pleased, come to the Great Council, and if they had done so the Great Council would have been much more numerously attended than the Witenagemot had been. The poorer tenants-in-chief, however, found that it was not only too troublesome and expensive to make the journey at a time when all long journeys had to be made on horseback, but that when they arrived their wishes were disregarded. They therefore stayed at home, so that the Great Council was regularly attended only by the bishops, the abbots of the larger abbeys, and certain great landowners who were known as barons. In this way the Great Council became a council of the wealthy landowners, as the Witenagemot had been, though the two assemblies were formed on different principles. 14. =The Gemot at Salisbury. 1086.=--In =1086=, after Domesday Book had been finished, William summoned an unusually numerous assembly, known as the Great Gemot, to meet at Salisbury. At this not only the tenants-in-chief appeared, but also all those who held lands from them as sub-tenants. "There came to him," wrote the chronicler, "... all the landowning men there were over all England, whose soever men they were, and all bowed down before him and became his men, and swore oaths of fealty to him, that they would be faithful to him against all other men." It was this oath which marked the difference between English and Continental feudalism, though they were now in other respects alike. On the Continent each tenant swore to be faithful to his lord, but only the lords who held directly from the crown swore to be faithful to the king. The consequence was that when a lord rebelled against the king, his tenants followed their lord and not the king. In England the tenants swore to forsake their lord and to serve the king against him if he forsook his duty to the king. Nor was this all. Many men break their oaths. William, however, was strong enough in England to punish those who broke their oaths to him, whilst the king of France was seldom strong enough to punish those who broke their oaths to him.
