Did Spain remain neutral during world war 2?

No, Spain did not remain neutral during World War II. Spain initially declared neutrality, but later provided support to the Axis powers, particularly Germany and Italy. For example, Spain provided troops to fight against the Allies in the Battle of Stalingrad, and also allowed German planes to use Spanish air bases. However, Spain did not officially enter the war on either side, and maintained a state of non-belligerence.
