Nicoya became a legal political, administrative and legal entity subject to the Villa de Bruselas township, controlled by the government of Castilla del Oro. In 1527, the Spanish Crown created the Province of Nicaragua, segregating it from Castilla de Oro, and included the territory of the Kingdom of Nicoya, since it was requested to establish whether the territory of the Villa de Bruselas (located at the southern tip of Nicoya) belonged to the Province of Nicaragua (the new circumscription), or if it remained under the authority of Castilla de Oro, and a Royal Decree of April 21, 1529 resolved the conflict in favor of the Province of Nicaragua, when the Villa had ceased to exist.
