The concentration in royal hands of so many powers which were formerly exercised by the lords and towns made necessary the development of a numerous and varied officialdom to assist the monarch. As the basis of the new bureaucracy in Castile the Catholic Kings had at hand the _Consejo Real_, which with some changes was admirably adapted to the purpose. The first step was to rid it of the great nobles. In 1480 the untitled _letrados_ became a majority in this body. The counts, dukes, and marquises were still allowed to attend, but were deprived of the right to vote. Shortly afterward they were excluded altogether, and the _Consejo Real_ now responded without question to the will of the king. It served as the head of the various branches of the bureaucratic organization, with the final decision, subject to the wishes of the king, in all matters of government. Pressure of work led to the formation of three additional councils, those of the Inquisition (_Inquisición_), the military orders, (_Órdenes Militares_), and the Americas, or Indies (_Indias_), while there were still others in the kingdom of Aragon. Particularly important among the other officials was the monarch’s private secretary, who came to have a very nearly decisive influence, owing to the favor he enjoyed with the head of the state. A horde of other officers, old and new, made up the ranks of the bureaucracy. Among the older group it is to be noted that the _adelantados_ were supplanted by _alcaldes mayores_, until only one of the former was left. Among newer officials the important inquisitors and _veedores_, or _visitadores_, should be noted. [Sidenote: Administration of justice.]
