Geronimo (Mescalero-Chiricahua: Goyaa?é [kòjà????] "one who yawns"; June 16, 1829 – February 17, 1909) was a prominent leader of the Bedonkohe Apache who fought against Mexico and the United States for their expansion into Apache tribal lands for several decades during the Apache Wars. "Geronimo" was the name given to him during a battle with Mexican soldiers. His Chiricahua name is often rendered as Goyathlay or Goyahkla[2][3] in English.

After an attack by a company of Mexican soldiers killed his mother, wife and three children in 1858, Geronimo joined revenge attacks on the Mexicans.[4] During his career as a war chief, he was notorious for consistently urging raids upon Mexican Provinces and their towns, and later against American locations across Arizona, New Mexico and western Texas.[5]

In 1886 Geronimo surrendered to U.S. authorities after a lengthy pursuit. As a prisoner of war in old age he became a celebrity and appeared in fairs[6] but was never allowed to return to the land of his birth. He later regretted his surrender and claimed the conditions he made had been ignored. Geronimo died in 1909 from complications of pneumonia at Fort Sill, Oklahoma.
