paternalistic rule by a more 'advanced' nation". Further development Assumptions about the caste system in Indian society, along with its nature, evolved during colonial rule. Corbridge concludes that British policies towards India's numerous princely sovereign states, as well as enumeration of the population into rigid categories during the 10-year census, particularly with the 1901 and 1911 census, contributed towards the hardening of caste identities. Social unrest during 1920s led to a change in this policy. From then on, the colonial administration began a policy of positive discrimination by reserving a certain percentage of government jobs for the lower castes. In the round table conference held on August 1932, upon the request of Ambedkar, the then Prime Minister of Britain, Ramsay MacDonald made a Communal Award which awarded a provision for separate representation for the Muslims, Sikhs, Christians, Anglo-Indians, Europeans and Dalits. These depressed classes were assigned a number of seats to be filled by election from special constituencies in which voters belonging to the depressed classes only could vote. Gandhi went on a hunger strike against this provision claiming that such an arrangement would split the Hindu community into two groups. Years later, Ambedkar wrote that Gandhi's fast was a form of coercion. This agreement, which saw Gandhi end his fast and Ambedkar drop his demand for a separate electorate, was called the Poona Pact. After India achieved independence, the policy of caste-based reservation of jobs was formalised with lists of Scheduled Castes and Scheduled Tribes. Other theories and observations Smelser and Lipset propose in their review of Hutton's study of caste system in colonial India the theory that individual mobility across caste lines may have been minimal in India because it was ritualistic. They state that this may be because the colonial social stratification worked with the pre-existing ritual caste system. The emergence of a caste system in the modern form, during the early period of British colonial rule in the 18th and 19th century, was not uniform in South Asia. Claude Markovits, a French historian of colonial India, writes that Hindu society in north and west India (Sindh), in late 18th century and much of 19th century, lacked a proper caste system, their religious identities were fluid (a combination of Saivism, Vaisnavism, Sikhism), and the Brahmins were not the widespread priestly group (but the Bawas were). Markovits writes, "if religion was not a structuring factor, neither was caste"
