Ranjit Singh, popularly known as
Sher-e-Punjab or "Lion of Punjab", was the first Maharaja of the Sikh Empire, which ruled the northwest Indian subcontinent in the early half of the 19th century. He survived smallpox in infancy but lost sight in his left eye. He fought his first battle alongside his father at age 10. After his father died around Ranjit's early teenage years, Ranjit subsequently fought several wars to expel the Afghans throughout his teenage years. At the age of 21, he was proclaimed the "Maharaja of Punjab". His empire grew in the Punjab region under his leadership through 1839.
