In 1727, the first attempt to unify what would later become the Province of Cantabria occurred. Despite this, the high level of autonomy that the small entities of the fractured estate of Cantabria enjoyed, combined with a lack of resources, continued to be the main reason for Cantabria's weakness, aggravated by the progressive advance of the Bourbonic centralism and its administrative efficiency. The latter continually emphasised the impossibility of the smaller territories facing a multitude of problems on their own: from communications to the exercise of justice, from putting aside adequate reserves for hard times to the indiscriminate levees for soldiers, and above all the progression of fiscal impositions. All of this led to an acceleration of contact between villas, valleys and jurisdictions, which tended to focus on the Assemblies of the Provinces of the Nine Valleys, led by the deputies elected by the traditional entities of self-government.
