"Nubia was a region of the Nile River, straddling on the borders of today's Egypt and Sudan. Nubians were among the best archers of the day. Using an innovative thumb ring that allowed them to draw their bows fully without injuring fingers, the Nubians were able to shoot their weapons a great distance. Throughout ancient history, Nubia and Egypt existed uneasily side by side. In some periods Nubian and Egyptian pharaohs intermarried, while in others Egypt conquered Nubia, or vice-versa. For many years Nubian mercenaries served as guards and police in Egyptian cities, strong indication of how close the civilizations were - and how tough the Nubian warriors were."
