In this General Assembly a framework was established and formal steps began to be taken, leading to administrative and legal unity in 1778. This all culminated in the success of the Assembly held in the Assembly House of "Puente San Miguel" on July 28, 1778, where the Province of Cantabria was constituted. It was achieved by passing the common ordinances which had been developed to that end, and which had been discussed and approved previously in councils of all the villas, valleys and subscribed jurisdictions. They were, in addition to the Nine Valleys: Rivadedeva, Peñamellera, the Province of Liébana, Peñarrubia, Lamasón, Rionansa, the Villa of San Vicente de la Barquera, Coto de Estrada, Valdáliga, the Villa of Santillana del Mar, Lugar de Viérnoles, the Villa of Cartes and environs, the Valley of Buelna, the Valley of Cieza, the Valley of Iguña with the Villas of San Vicente and Los Llares, the Villa of Pujayo, the Villa of Pie de Concha y Bárcena, the Valley of Anievas, and the Valley of Toranzo.
