Reformism is a political doctrine advocating the reform of an existing system or institution instead of its abolition and replacement.[1]

Within the socialist movement, reformism is the view that gradual changes through existing institutions can eventually lead to fundamental changes in a society's political and economic systems. Reformism as a political tendency and hypothesis of social change grew out of opposition to revolutionary socialism, which contends that revolutionary upheaval is a necessary precondition for the structural changes necessary to transform a capitalist system to a qualitatively different socialist system. Responding to a pejorative conception of reformism as non-transformational, non-reformist reform was conceived as a way to prioritize human needs over capitalist needs.[2]
