Loyalism
In general loyalism refers to an individual's allegiance toward an established government, political party, or sovereign, especially during times of war and revolt. The most common usage of the term refers to loyalty to the Great Britain, especially to opponents of the American Revolution and those exiles who went to Canada.
The term loyalist was also used during the Spanish Civil War, applying to Republicans who remained loyal to the Spanish Republic against Franco's "Nationalists."
