The Pact of Madrid, signed in 1953 by Spain and the United States, ended a period of virtual isolation for Spain. This development came at a time when other victorious allies of World War II and much of the rest of the world remained hostile to what they regarded as a fascist regime sympathetic to the Nazi cause and established with Axis assistance. The 1953 accord took the form of three separate executive agreements that pledged the United States to furnish economic and military aid to Spain. The United States, in turn, was to be permitted to construct and to utilize air and naval bases on Spanish territory (Naval Station Rota, Morón Air Base, Torrejón Air Base and Zaragoza Air Base).
