The most important historical event of this century is the return of Asturian land back to the territories of Peñamellera Baja in 1833, thanks to the new territorial distribution in Spain; a year later the valley of Peñamellera asked, along with Rivadedeva, re-entry into the Province of Santander. The request was denied, disassociating themselves from Cantabria and becoming part of the province of Oviedo. Then arguments began between Alles and Abándames for who would have the capital. In 1869, cuetos administratively separated the two remaining cuetos, so that Abándames remained as the low valley. This situation lasted until 1890, at which time the capital was transferred to Panes, a town that experienced a progressive increase in its population.
