They attacked the axis powers in Germany, Russia and many other opposing sides of the war.
The type of government that Spain have in 16th century is monarchy. Monarchy is a form of government, which a family embodies a country's national identity. The monarch, which was the head of the family, exercises the role of the sovereignty. The monarch may either be purely symbolic (crowned republic), has partial or restricted power (constitutional monarchy), or has the complete power (absolute monarchy).
