Among the Apache Indians who resisted government removal of their people from treaty-guaranteed reservations in the late nineteenth century, Geronimo was the boldest and most determined. Beginning in the mid-1870's, he led his Chiricahua warriors in numerous raids designed to thwart efforts to displace his people from their Southwest lands, and by 1885 he was orchestrating an all-out campaign against white settlements in parts of Arizona and New Mexico. Finally, however, he fell into federal custody in 1886, and following his confinement in several prisons, he was allowed to settle in Oklahoma, where he took up farming.
