Sir, a group of unidentified armed individuals took control of the Senate Building and killed several commandos, as a riot distracted the security in the area. We are doing our best to regain control of the situation.
—A Senate Commando captain to Mace Windu
The Reformist coup d'état, also called the Coruscant coup or Republic coup, was an attempt by the Reformist Movement to take control of the government of the Galactic Republic in 21 BBY. Large protests in the senate district distracted law enforcement officials, during which a group of militants broke into the Senate Building, taking control of a part of it, and engaging in firefights with security. As it became apparent that the protests were a distraction, a team of Jedi, with the Coruscant Guard and Security Force personnel, retook the building from the militants.
