Kingdom of Aragon
Over time, the king will begin to create a network of officials to control the lands and towns directly dependent on him, called realengo. The merino was an executive, judicial and military agent of the monarch that is already documented in the Fuero de Jaca. The bailes began with similar competencies, but ended up specializing in the management of the royal patrimony. The king granted to cities and villas of royalty privileges that specified the privileges of their neighbors. The regions of Daroca, Teruel, Calatayud, Albarracín and others were organized into communities that sent their own representatives to the Cortes. In the 15th century, the territory of the kingdom was divided into eleven overcollides for tax purposes, which were converted into paths, with some modifications, in the 17th century.
