Mirambel did not play a military role for Carlism. Its position in the valley, among other points much more susceptible to fortification and under the protection of Cantavieja, determined that it was a bustling political enclave full of activity. The Junta Superior Gubernativa de Aragón, Valencia and Murcia, which supported the work of Cabrera in his governmental actions, had its headquarters here.

With the establishment of a court of appeal, the beginning of a judicial structure was outlined. Closely linked to these political tasks, a printing press operated within its walls to disseminate the orders issued by its organs throughout the territory.
