The term 'Scheduled Castes' (SCs) finds its administrative and legal genesis in the Government of India Act, 1935, where the British colonial administration consolidated various depressed classes, untouchables, and exterior castes into a schedule for targeted electoral representation and protective discrimination. Etymologically, the term supersedes derogatory and pejorative nomenclature such as 'Untouchables' (Mahatma Gandhi's Harijans) and 'Exterior Castes' (J.H. Hutton).
- Classical Sociological Conceptualization: Auguste Comte's Law of Three Stages and Émile Durkheim's mechanical solidarity highlight how rigid traditional hierarchies suppress individual differentiation. Max Weber categorized the caste system as the prime archetype of status groups (Stand) operating on closed social closure, ritual purity, and hereditary honor.
- B.R. Ambedkar’s Structural Critique: In seminal works such as Annihilation of Caste (1936) and Who Were the Shudras? (1946), Dr. B.R. Ambedkar rejected the organic/functionalist justification of caste (such as the Purusha Sukta myth) and formulated it as a division of laborers engineered to enforce graded inequality, economic exploitation, and religious subjugation.
- G.S. Ghurye’s Indological Parameters: In Caste and Race in India (1932), Ghurye delineated six cardinal features of the caste system: (1) Segmental division of society, (2) Hierarchy, (3) Civil and religious disabilities and privileges of different sections, (4) Lack of unrestricted choice of occupation, (5) Restriction on feeding and social intercourse, and (6) Endogamy. Scheduled Castes historically suffered the most acute deprivations across all six parameters.
