The history of all ancient societies is the history of class struggle. In each of these we find a complicated arrangement of people into various social, economic, and political orders.

During the middle ages there were three orders; oratores, bellatores, laborares: this translates as "those who pray", "those who fight", and "those who work". http://jxb7076.hubpages.com/hub/The-Left-the-Right-and-the-Communist-Agenda
