Some of them served in the British Indian army after being raised as Sikhs. The Sikh religion was founded by Guru Nanak, a Bedi Khatri. Subsequently, all the Sikh religious leaders or Gurus were Khatris. During the Sikh Empire, many Khatris formed the military vanguard of the Khalsa Army and its administrative class as Dewans of all the provinces. Hari Singh Nalwa, the commander-in-chief of the Sikh Khalsa Army, was an Uppal Khatri and responsible for most of the Sikh conquests uptill the Khyber pass. Others such as Mokham Chand commanded the Sikh Army against the Durrani Empire at Attock while those such as Sawan Mal Chopra ruled Multan after wrestling it from the Afghans. Khatris have played an active role in the Indian Armed Forces since 1947, with many heading it as the Chief of Army or Admiral of the Navy. Some such as Vikram Batra and Arun Khetarpal have won India's highest wartime gallantry award, the Param Vir Chakra. During the Partition of British India in 1947, many Khatris migrated to India from the regions that comprise modern-day Pakistan. Hindu Afghans and Sikh Afghans are predominantly of Khatri and Arora origin. Etymology The word Khatri in the Hindi Language comes from the Sanskrit word "Kshatriya" according to the Śabdasāgara Lexicon by Shyamasundara Dasa According to B. N. Puri, philologists agree that the terms "Khatri" and "Kshatriya" are synonymous. The Sanskrit conjunct Ksha (क्ष) turns into the Prakrit Kha (ख) as per the grammarian Vararuchi. This change is not only accepted in Prakrit but in all Indian vernaculars derived by it such as Gujarati, Urdu, Gurumukhi as well as Persian. For example, Sanskrit words kshetra, kshama, laksha, iksha turns into kheta, khama, lakha and ikha respectively. The substituition of Ri (ऋ) from Riya is also witnessed in case of Hindi. Hence,
