The Corporate Alliance is a negotiating body for several of galaxy's major business firms serving as one of the corporate backers of the Confederacy of Independent Systems during the Clone Wars, and are an antagonistic faction in the Star Wars franchise.
The Corporate Alliance was a massive business entity prior to the end of the Clone Wars, which earned it representation in the Senate of the Galactic Republic.
During the Clone Wars, the Corporate Alliance supported the Confederacy of Independent Systems by supplying them with its NR-N99 Tank Droid models. The Corporate Alliance was among the most enthusiastic backers of the CIS, even funding propaganda against the Republic and the Jedi.
At the end of the Clone Wars, the Commerce Guild Magistrate Passel Argente was killed by Darth Vader along with the other Separatist leaders and the Alliance's assets were annexed by the Galactic Empire.
