Geonosis

Geonosis is a barren red planet, not unlike Mars, that is home to the race of bug-like creatures known as the Geonosians. A large planet with many rings, Geonosis is home to the primary droid factories of the CIS. It was their main base at the start of the Clone War until it was attacked by the Republic after several hundred Jedi, led by Macey Space, were sent there to rescue Obi-Wan Kenobi, Anakin Skywalker, Padme Amidala, C-3PO and R2-D2 from the grip of the CIS. The battle that followed marked the first deployment of the Clone Troopers, thus making this the first battle of the Clone War.

The Seperatists immidietly evactuated most of Geonosis and spread across the Galaxy to wage war on all fronts. After this, Geonosis was largely forgotten, apart from the fact that Poggle the Lesser remained a leading member of the CIS Council. Jango Fett also rested here for a time and he was killed in the arena battle, leaving Boba Fett alone on the planet.
