attacked the city, people fled to Gujarat and it became independent. Afghanistan According to historians Roger Ballard and Harjot Oberoi, Afghan Hindus and Sikhs descend from the members of the country's indigenous Khatri population who resisted the conversion from Buddhism to Islam between 9th and 13th centuries. Later, they aligned themselves to the teachings of Guru Nanak, himself a Khatri and converted to Sikhism. Hence, Khatris of Afghanistan are in no way of "Indian origin" but are components of the original population of the region. George Campbell says "I do not know the exact limits of Khatri occupation to the West, but certainly in all Eastern Afghanistan they seem to be just as much part of the community as they are in the Punjab. They find their way into Central Asia." Sikh Empire The Khatris took on a prominent role in the emerging Sikh milieu of post-Mughal Punjab. According to the Khalsa Durbar Records, Maharaja Ranjit Singh's army was composed of majorly Jats followed by Khatris. Sardar Gulab Singh Khatri founded the Dallewallia Misl, an independent 18th century Sikh sovereign state in Ludhiana and Jalandhar district that would later on join Maharaja Ranjit Singh's kingdom. In the Sikh Empire, Hari Singh Nalwa (1791–1837) an Uppal Khatri from Gujranwala, became the Commander-in-chief of the Sikh Khalsa Army. He led the Sikh conquests of Kasur, Sialkot, Attock, Multan, Kashmir, Peshawar and Jamrud. He was responsible for expanding the frontier of Sikh Empire to beyond the Indus River, up to the mouth of the Khyber Pass. At the time of his death, the western boundary of the empire was Jamrud. Dewan Mokham Chand (1750-1814) became one of the most distinguished leaders of the Khalsa Army. He was the commander in chief of armies in Battle of Attock which defeated Durrani Empire Wazir Fateh Khan and Dost Mohammad Khan Other Khatris like Diwan Sawan Mal Chopra served as governors of Lahore and Multan, after helping conquer the region while his son Diwan Mulraj Chopra, (1814-1851) the last Punjabi ruler of Multan led a Sikh rebellion against British suzerainty over Multan after the fall of the Sikh Empire in the Anglo-Sikh Wars. He was arrested after the Siege of Multan and put to death. Purnima Dhawan described that together with Jat community, the Khatris gained considerably from the expansion of the Mughal empire, although both groups supported Guru Hargobind in his campaign for Sikh self-government
