Question

how revolutionary groups works?​

Answer 1

According to the goals of the revolution they propose. Usually, these goals are part of a certain ideology. In theory, each ideology could generate its own brand of revolutionaries. In practice, most political revolutionaries have been either anarchists, communists, or socialists.

According to the methods they propose to use. This divides revolutionaries in two broad groups: Those who advocate a violent revolution, and those who are pacifists.
