Spain and Portugal hated Napoleon, France, because it swept the European continent in the first five years of the19th century, when France was the first empire of France. Portugal has always been anti-French (mainly pro-British), and Spain is originally the French camp. Later, Napoleon wanted his younger brother Joseph to be king of Spain, which aroused the resistance of the whole Spanish nation and broke out the Spanish people's war against France. During World War II (standard: 1939), the two countries were neutral countries. PS: Although Nazi Germany was the "ally" of General Franco, the Spanish "Spear Party", the Spanish Civil War (1936~ 1939) was only a civil war in which the left and right factions fought for political power, and the left-wing United Front (the forces that seized political power with the "Spear Party") was also supported by the international joint camp. After the outbreak of World War II, General Franco sent three or four divisions as volunteers to join the Soviet-German war, which was a friendly response. A few volunteer divisions are also suspected of speculation and ambiguity, and they are "fence-sitters".
