The Apache are a Native American TRIBE that originated in the Southwest United States. The term 'Apache' is derived from the Yuma word for 'fighting-men'. The most famous Apache leader was Geronimo, who led the Chiricahua Apache TRIBE in a series of battles against the U.S. Army in the late 1800s. Another prominent Apache leader was Cochise, who led the Chokonen band of the Chiricahua Apache. The Apache were known for their fierce resistance to the U.S. government and their ability to survive in harsh conditions. They often used guerrilla tactics to fight against the U.S. Army, such as raiding forts and settlements.
