What are some lesser-known socialist movements in history

So we all know about the soviet union, china, and Cuba but what are some lesser-known socialist countries or sizeable socialist movements in history? An example of this could be the Zapatistas, Burkino Fasso, the Paris commune, or republican Spain. I don't really care if they are specifically Marxist Leninist(although that is preferred and I know not all the examples above are ML or even socialist according to some people but that's not the point) I'm just looking for some leftist history.
