Since their initial founding in 1899, the constitutionalists were constantly ineffective in their effort to reform authoritarian governments. Their soft reformist approach was criticized for giving dictatorships the appearance of a legitimate multi-party democracy. Because of their anti-confrontational nature, they were more of a complaining party than an opposition party. The only time they were effective was when they abandoned reform in favor of revolution in the National Protection War.
