In early decades of the 19th-century, the Lingayats were described by British officials such as Francis Buchanan as a conglomeration of Hindu castes with enormous diversity and eclectic, egalitarian social system that accepted converts from all social strata and religions. However, the British officials also noted the endogamous tradition and hereditary occupations of many Lingayats, which made their classification difficult. In the 1871 and the 1881 colonial era census of British India, Lingayats were listed as "shudras". According to the sociologist M. N. Srinivas, Lingayats traditionally believed themselves to be equal in status to Brahmins, and some orthodox Lingayats were so anti-Brahmin that they would not eat food cooked or handled by Brahmins. The egalitarian Lingayats, states Srinivas, had been a major force in Sanskritization of Kannada-speaking (Karnataka) and nearby regions but against elitism.
