Anarchism is a radically revolutionary idea that says no one should be forced into any kind of hierarchy. For example, anarchism says that the government is harmful and not needed. However, that does not mean no form of order should exist. Municipalities and autonomy are familiar terms in Anarchism[1][2] It also says that people's actions should never be forced by other people. Anarchism is also a philosophical movement and is called a libertarian type of socialism. It is not a political stance.
The word "anarchism" is from the Greek word "αναρχία", which means "no rulers" or "no government". But that does not have to to mean no rules at all. People often use the word "anarchy" to mean chaos and crime. But anarchists usually do not want this. They say anarchy is just a way of relations between people. They believe that, once put into place, these relations work on their own. Anarchists are usually opposed by the systems they wish to remove.
