Star Wars - The Clone Wars

The Clone Wars (22–19 BBY) was a galaxy-spanning conflict between the Galactic Republic and the Confederacy of Independent Systems, which had seceded from the Republic. Also referred to as the Clone War, it was named after the clone troopers used by the Grand Army of the Republic against the Separatist Droid Army. With both being fielded in enormous numbers by each respective side, they were the largest military forces in galactic history, and fighting between them swept through the galaxy for three, nearly four, years.
