Anarchism
The word "anarchism" is from the Greek word "αναρχία", which means "no rulers" or "no government". But that doesn't have 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.
