This era of conflict was part of the broader Apache–United States struggle, which arose after American colonization of Apache territories following the conclusion of the U.S.-Mexico War in 1848. For the Apaches, life on government-imposed reservations clashed with their fiercely independent spirit and traditional nomadic lifestyle. Geronimo emerged as a key figure leading resistance against these constraints. Despite his reputation, Geronimo was not a chief of the Chiricahua or Bedonkohe bands. However, his exceptional skills as a leader in raids and warfare earned him the loyalty of many Apache warriors, often commanding between 30 and 50 fighters at a time.
