Amidst opposing political ideals in Spain, the growing Industrial revolution and constant conflict in Spanish politics, the Third Carlist War was a culmination of a long political process. The political appearance of the conflict, exemplified by the struggle for the Spanish crown, masked a more crude reality. The growth of liberal ideals after Napoleon Bonaparte's occupation of Spain and Spain's subsequent fight for independence alarmed Spain's traditional groups, who decided to fight for their beliefs. Tumultuous reigns of monarchs Ferdinand VII, Isabel II and Amadeo I exemplified the political unrest present in Spain, and resulted in the loss of traditionalist predominance, especially during the reign of Isabel II.
