Guernica (Gernika in Basque; officially Gernika-Lumo), in the Basque province of Biscay, and 30 kilometres east of Bilbao, has long been a centre of great significance to the Basque people. Its Gernikako Arbola ("the tree of Gernika" in Basque) is an oak tree that symbolizes traditional freedoms for the Biscayan people and, by extension, for the Basque people as a whole. Not only was Guernica considered the identity of Basque, but it was also considered the spiritual capital of Basque people. Guernica has always been celebrated as the home of Basque liberties. Guernica was also the location of the Spanish weapons manufacturer Astra-Unceta y Cía, which had been a supplier of firearms to the Spanish military and police forces since 1912. At the time of the bombing, the population of Guernica was 7,000 people, and the battlefront was 30 kilometres away.
