Step 1: Caste-based oppression:
Deep-rooted caste practices, untouchability, rigid hierarchy, and exclusion of lower castes and Dalits from public life, temples, schools and wells, were seen by reformers as unjust obstacles to a fair, modern society.
Step 2: Oppression of women:
Degrading practices against women, sati, child marriage, denial of widow remarriage, purdah, and lack of access to education and property rights, drove reformers to demand change in the status of women.
Step 3: Influence of new ideas:
Exposure to Western liberal/rationalist thought and missionary critique of Indian customs prompted Indian reformers to reassess their own traditions, using reason and scripture reinterpretation to argue that reform was consistent with, not a betrayal of, Indian culture.
Step 4: Key reformers and goals:
Figures like Raja Ram Mohan Roy, Jyotiba Phule, Ishwar Chandra Vidyasagar and Dr. B. R. Ambedkar led movements for education (including women's and Dalit education), the removal of superstition, and greater human dignity and equality.
Final Answer:
Socio-reform movements began to combat caste oppression and untouchability, the degraded status of women, and outdated superstitious practices, driven by reformers who combined rational critique with reinterpretation of tradition to pursue greater social equality and dignity.
