The Interprovincial Council of Santander, Palencia and Burgos was a governing body established on 8 February 1937 to coordinate the Republican areas in Cantabria (then officially called the Province of Santander), Palencia and Burgos during the Spanish Civil War.

[1] With the outbreak of war in July 1936, Cantabria and the northern parts of Palencia and Burgos remained under Republican control, as well as the neighboring Asturias and Biscay, while most of Castilla feel under nationalist rule.

[2] Following this order of the central government, the Interprovincial Council of Santander, Palencia and Burgos was officially constituted on 8 February 1937.

The government of the Republic delegated to the Council all functions except those of law enforcement, press and radio censorship, as well as meetings and public demonstrations.

The last agreements made during those days corresponded to a request for arms for the defense of the region and food with which to alleviate the situation of the population,[3] aggravated by the arrival of refugees from the nationalist-occupied areas.
