Meo (pronounced: may-o or mev), is an ethnic group of the Mewat region from north-western India, particularly from the Nuh district (previously Mewat district) in Haryana and parts of adjacent Alwar and Bharatpur districts in Rajasthan. They speak Mewati, a language of the Indo-Aryan language family, although in some areas the language dominance of Urdu and Hindi has seen Meos adopt these languages instead.
Meos are inhabitants of Mewat, a region that consists of the former Mewat district of Haryana and some parts of adjoining Alwar and Bharatpur districts of Rajasthan and Western Uttar Pradesh, where the Meos have lived for a millennium. According to one theory, they were Hindu Rajputs and Kashtriya who converted to Islam between the 12th and 17th century, until as late as Aurangzeb's rule. Over the centuries, they have maintained their age-old distinctive cultural identity. According to S. L. Sharma and R. N. Srivastava, Mughal persecution had little effect on the strengthening of their Islamic identity, but it reinforced their resistance to Mughal rule. They have shared this region with a number of other Muslim communities, such as Khanzada, Qaimkhani and Malkana.
A British Raj-era theory briefly suggested by the colonial ethnographer and political agent for Alwar State, Major P. W. Powlett, has it that the Meo are related to the Meenas (Minas). In Powlett's 1878 Gazetteer of Ulwur (later spelt Alwar), he comments: "The similarity between the words Meo and Mina suggests that the former may be a contraction of the latter". He continues by pointing out that several clans in both communities (Singal, Náí, Dúlot, Pimdalot, Dingal, Bálot) have identical names. He mentions the Meo's traditional narrative ballad of Dariyā Khān ("Daria Meo") and the story of his betrothal to Sisbadani, a Mina woman, their separation and reunion, as possibly suggestive of historical intermarriage between the groups.
According to Shail Mayaram, author, and professor of Subaltern Studies at the Centre for the Study of Developing Societies, this view was likely constructed for political reasons by colonial authorities.
