Other forms: revolutionists
Whether you’re overthrowing a government or protesting an unjust law, you could be called a revolutionist, someone who works for political or social change.
A revolutionist is someone who wants to change the world — not just sitting around talking about it, but actually doing something to bring about change. Like its synonyms revolutionary and radical, a revolutionist is someone who questions authority, maybe by taking part in a demonstration to protest a government policy or by otherwise pointing out thing that he or she believes is wrong with society — then acting to try to fix it.
