Kashyyyk (occasionally spelled Kashyk) is a jungle planet and the home of the Wookiee race and Chewbacca. It is a planet of the Republic but the Confederacy of Independent Systems launched an attack on the planet. The Republic sent Grand Master and Jedi General Yoda and Commander Gree with the 41st Elite Corps to liberate the planet. After Order 66 was executed, the clone troopers then turned on Yoda but he managed to escape and after the transformation of the Galactic Republic into the Galactic Empire, it became an Imperial planet.
After the fall of the Empire, Kashyyyk became an New Republic planet.
