The Black Forso were a group of anarchists who were formed in the wake of the Galactic Depression. Claiming the government was at fault for the depression, they gained hundreds of thousands of supporters in the galaxy and had toppled several governments on independent worlds.
They aligned themselves with the Triple Tsad after the start of the Great Alliance War. At the end of the war, the anarchists fought against the Vode Empire, still believing there should not be a government in the galaxy. The Vode left the anarchists alone for most of their reign until the Forso decided to rebel. They were quickly crushed.
