In the reign of the first Henry we can indeed trace the beginnings of differentiation in the machinery of government, but the process was as yet wholly unconscious. We find in this reign evidence of a large curia regis and of a small curia regis. The difference had probably existed in the two preceding reigns, but it now becomes more apparent because the increasing business of the state makes it more prominent. More frequent meetings of the curia regis were necessary, but the barons of the kingdom could not be in constant attendance at the court and occupied with its business. The large court was the assembly of all the barons, meeting on occasions only, and on special summons. The small court was permanently in session, or practically so, and was composed of the king's household officers and of such barons or bishops as might be in attendance on the king or present at the time. The distinction thus beginning was destined to lead to most important results, plainly to be seen in the constitution of to-day, but it was wholly unnoticed at the time. To the men of that time there was no distinction, no division. The small curia regis was the same as the larger; the larger was no more than the smaller. Who attended at a given date was a matter of convenience, or of precedent on the three great annual feasts, or of the desire of the king for a larger body of advisers about some difficult question of policy; but the assembly was always the same, with the same powers and functions, and doing the same business. Cases were brought to the smaller body for trial, and its decision was that of the curia regis. The king asked advice of it, and its answer was that of the council. The smaller was not a committee of the larger. It did not act by delegated powers. It was the curia regis itself. In reality differentiation of old institutions into new ones had begun, but the beginning was unperceived.
