Alceda was formed by the sum of ten councils located in the center of the Royal Valley of Torazno, on the bank of the Pas River.

The population was under a regime of behetry (they had the right to elect their lord) and over the centuries they fought to protect it from those usurpers who tried to subdue them under a lordly regime, as the Manrique, who finally managed to annex the territory to the County of Castañeda.

These struggles gave rise to the so-called Lawsuit of the Valleys. They fought for their freedom, which was not recognized until the late eighteenth century. The municipality was consolidated in 1835 with the current dimensions and names.
