Summary: This study delves into the social changes and dominant ideas in Bengal from 1772 to 1858 under the East India Company, shedding light on Sati, Slavery, Thagi, and Infanticide. The period saw upheavals in public opinion, governance, education, and social norms, with influential figures like Rammohan Roy, Dwarkanath Tagore, and zamindars playing pivotal roles. The clash between the conservative zamindars and indigo planters revealed societal tensions, while the Bengal Government grappled with regulating the press, education policies, and revenue laws. Efforts to introduce reforms and navigate the diverse concerns of different communities led to petitions, protests, and government responses, reflecting a nuanced interplay of public sentiment, political maneuvering, and evolving social norms. The study uncovers the dynamics of colonial rule, public opinion, and social reform in a formative period of Indian history under East India Company governance.
