Lion Additional Information: Singh is a common title, middle name, or surname used in South Asia, mainly in India, Nepal, and Sri Lanka and Bangladesh, originally used by Hindu Kshatriya warriors and kings. It is derived from the Sanskrit word Siṃha meaning "lion". It is also used in Sri Lanka by Sinhalese people and in Nepal by Newa people. Narsingh is an avatara of Vishnu described in the Puranas, Upanishads and other ancient religious texts of Hinduism, and one of Hinduism's most popular deities, as evidenced in early epics, iconography, and temple and festival worship for centuries. It was later adopted into Sikhism in 1699 as per the instructions of Sri Guru Gobind Singh Ji, the use of Singh as a last name is mandatory for all baptized male Sikhs since 1699, regardless of their geographical or cultural binding. The surname has also been widely adopted by other groups of India like Yadavs and Jats. Some Brahmins like Bhumihar Brahmins (see Kingdom of Kashi and Royal House of Benares) and Maithil Brahmins (see History of Mithila) also use this name. "Singh" has gradually emerged as a hereditary title to be used as a middle name, highlighting connections to a warrior status or occupation. However, this is not an exclusive usage, and many Hindu groups including Scheduled Castes and Vaishya have adopted this title without any significant warrior status or ties.
