On the other hand, the royal power continued to exist, being recognized by a considerable part of old Gaul, the _regnum Francorum_. But under the last of the Carolingians it had in fact become elective, as is shown by the elections of Odo and Robert before that of Hugh Capet. The electors were the chief lords and prelates of the _regnum Francorum_. But following a clever policy, each king during his lifetime took as partner of his kingdom his eldest son and consecrated and crowned him in advance, so that the first of the Capetians revived the principle of heredity in favour of the eldest son, while establishing the hereditary indivisibility of the kingdom. This custom was recognized at the accession of Louis the Fat, but the authority of the king was very weak, being merely a vague allegiance. His only real authority lay where his own possessions were, or where there had not arisen a duke, a count, or lord of equal rank with them. He maintained, however, a general right of administering justice, a _curia_, the jurisdiction of which seems to have been universal. It is true that the parties in a suit had to submit themselves to it voluntarily, and could accept or reject the judgment given, but this was at that time the general rule. The king dispensed justice surrounded by the officers of his household (_domestici_), who thus formed his council; but these were not the only ones to assist him, whether in court or council. Periodically, at the great yearly festivals, he called together the chief lords and prelates of his kingdom, thus carrying on the tradition of the Carolingian _placita_ or _conventus_; but little by little, with the appropriation of the _honores_, the character of the gathering changed; it was no longer an assembly of officials but of independent lords. This was now called the _curia regis_. The Church.
