sanitation work is Valmiki (also Balmiki) caste. History Gopal Baba Walangkar (c. 1840–1900) is generally considered to be the pioneer of the Dalit movement, seeking a society in which they were not discriminated against. Another pioneer was Harichand Thakur (c. 1812–1878) with his Matua organisation that involved the Namasudra (Chandala) community in the Bengal Presidency. Ambedkar himself believed Walangkar to be the progenitor. Another early social reformer who worked to improve conditions for Dalits was Jyotirao Phule (1827–1890). The 1950 Constitution of India, introduced after the country gained independence, included measures to improve the socioeconomic conditions of Dalits. Aside from banning untouchability, these included the reservation system, a means of positive discrimination that created the classifications of Scheduled Castes, Scheduled Tribes for Dalits. Communities that were categorised as being one of those groups were guaranteed a percentage of the seats in the national and state legislatures, as well as in government jobs and places of education. The system has its origins in the 1932 Poona Pact between Ambedkar and Gandhi, when Ambedkar conceded his demand that the Dalits should have an electorate separate from the caste Hindus in return for Gandhi accepting measures along these lines. The notion of a separate electorate had been proposed in the Communal Award made by the British Raj authorities, and the outcome of the Pact – the Government of India Act of 1935 – both introduced the new term of Scheduled Castes in replacement for Depressed Classes and reserved seats for them in the legislatures. By 1995, of all federal government jobs in India – 10.1 per cent of Class I, 12.7 per cent of Class II, 16.2 per cent of Class III, and 27.2 per cent of Class IV jobs were held by Dalits. Of the most senior jobs in government agencies and government-controlled enterprises, only 1 per cent were held by Dalits, not much change in 40 years. In the 21st century, Dalits have been elected to India's highest judicial and political offices. In 2001, the quality of life of the Dalit population in India was worse than that of the overall Indian population on metrics such as access to health care, life expectancy, education attainability, access to drinking water and housing.
