Geronimo

Geronimo loosely means "one who yawns"; was born on June 16, 1829 was a prominent Native American leader of the Chiricahua Apache who fought against Mexico and the United States for their expansion into Apache tribal lands for several decades during the Apache Wars. After an attack by a company of Mexican soldiers killed many members of his family in 1858, Geronimo joined revenge attacks on the Mexicans. During his career as a war chief, Geronimo was notorious for consistently urging raids and war upon Mexican Provinces and their various towns, and later against American locations across Arizona, New Mexico, and western Texas. 
In 1886 Geronimo was eventually tracked down by U.S. authorities and surrendered. As a prisoner of war in old age he became a celebrity and appeared in fairs 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 after being thrown from his horse. 
Later in life, Geronimo embraced Christianity, and stated, "Since my life as a prisoner has begun I have heard the teachings of the white man's religion, and in many respects believe it to be better than the religion of my fathers ... Believing that in a wise way it is good to go to church, and that associating with Christians would improve my character, I have adopted the Christian religion. I believe that the church has helped me much during the short time I have been a member. I am not ashamed to be a Christian, and I am glad to know that the President of the United States is a Christian, for without the help of the Almighty I do not think he could rightly judge in ruling so many people. I have advised all of my people who are not Christians, to study that religion, because it seems to me the best religion in enabling one to live right."
