One of the history electives we could take in high school was called something like "The isms." If I remember it was a full semester history elective. Since I like studying history, I chose it. It was extremely interesting. Although many of them are religion based, the class didn't delve too deep into the religion part of it but in how the followings impacted history, governments, culture and how they differed from others.
Each week or two where we learned about and talked about each of the main "isms" in class, some short readings and homework. Isms like Socialism, Fascism, Taoism, Buddhism, Judaism, Marxism, Totalitarianism, Communism, Islamism, Monarchism were all different modules of the class. It didn't go into Capitalism as that was learned about in American history classes and economics classes. Instead it focused on historical and political structures outside of the USA. For the final paper you had to pick one of them to do further research and also give a small oral presentation to the class.
Like I said, it was an extremely interesting and fun class to lean about all the different ones that humans have developed and followed (or fought against) over the modern and historical years. I think I chose Taoism for my final project.
