Sitting Bull was born on land later included in the Dakota Territory. In 2007, Sitting Bull's great-grandson asserted from family oral tradition that Sitting Bull was born along the Yellowstone River, south of present-day Miles City, Montana. He was named Jumping Badger at birth, and nicknamed Hunkesi, or "Slow," said to describe his careful and unhurried nature. When the boy was fourteen years old he accompanied a group of Lakota warriors (which included his father and his uncle Four Horns) in a raiding party to take horses from a camp of Crow warriors. Jumping Badger displayed bravery by riding forward and counting coup on one of the surprised Crow, which was witnessed by the other mounted Lakota. Upon returning to camp his father gave a celebratory feast at which he conferred his own name upon his son. The name, Tȟatȟáŋka Íyotake, which in the Lakota language means "Buffalo Bull Who Sits Down", would later be abbreviated to "Sitting Bull". Thereafter, Sitting Bull's father was known as Jumping Bull. At this ceremony before the entire band, Sitting Bull's father presented his son with an eagle feather to wear in his hair, a warrior's horse, and a hardened buffalo hide shield to mark his son's passage into manhood as a Lakota warrior.
