The Battle of Bilbao was part of the War in the North, during the Spanish Civil War where the Nationalist Army captured the city of Bilbao and the remaining parts of the Basque Country still held by the Republic.
Bilbao was the capital of the autonomous Basque area established by the Republic after the war began. This establishment was in payment for Basque Nationalist support of the Republic. The Basque people in Spain generally inhabit four provinces, Navarre, Álava, Gipuzkoa and Biscay. The Basque Nationalists were dominant in the latter two provinces. Navarre and Álava had rallied to the rising against the Republic.
