Harjot Singh Oberoi is a Professor of Asian Studies at the University of British Columbia, Vancouver.
Oberoi wrote The Construction of Religious Boundaries: Culture, Identity, and Diversity in the Sikh Tradition.
Sikhs did not establish distinct religious boundaries until the Singh Sabha Movement, according to Oberoi.
[1] Sociologist T. N. Madan states Oberoi is a "careful Sikh scholar",[2] while the Sikhism historian W. H. McLeod has called his book as "superb" that "successfully challenges the accepted historiography and is "very significant" to Sikh history studies.
[3] Tony Ballantyne states that Oberoi's studies of late 19th-century and early 20th-century religious developments in British India is the "most sophisticated cultural analysis of social change".
