B1 Battle Droids (simply known as Battle Droids) are a series of combat droids from the Star Wars universe. The Trade Federation made extensive use of these droids and as the military force for the Confederacy of Independent Systems during the Clone Wars until they were outlawed by the Galactic Empire. They were created by the insectoid race known as the Geonosians and were produced in Geonosis' foundries in massive numbers. They also bore a resemblance to their creators, having a similar head shape and being thin and spindly.
