In June of 1829, Geronimo was born into the Apache Indian tribe. He was a master hunter who is believed to have swallowed the heart of his first kill to ensure a life of success. In Geronimo's earlier years, he was almost always on the run. His tribe of around 8000 people were surrounded by enemies. Raiding nearby tribes was also a very common Apache activity. By the time Geronimo was 17, he had led many successful raids. It was around this time Geronimo also fell in love with a woman named Alope.
