Charles III also initiated the difficult process of changing the complex administrative system practiced under the former ruling family, the House of Habsburg. "Corregidores" were to be replaced with a French institution, the intendant. The intendancies had the intended effect of further decentralizing the administration at the expense of viceroys, captains general and governors, since intendants were directly responsible to the Crown and were granted large powers in economic and political matters. The intendancy system proved to be efficient in most areas and led to an increase in revenue collection. Intendency seats were mainly based in large cities and successful mining centers. Almost all of the new intendants were Peninsulares, people who were born in Spain, exacerbating the conflict between Peninsulares and Criollos, who wished to retain some control of local administration. The installation of the intendancy system contributed to the further marginalization of the creole elite. It changed the question of who would occupy the positions of Crown officials and shifted the center of influence from landed Creole elites to peninsular Spaniards. Creoles were largely pushed out in favor of peninsular administrators.
