Chapter 5 of Class 8 Social Science, Understanding Marginalisation, focuses on the concept of marginalisation, which refers to the social exclusion of certain groups from mainstream society, often resulting in their lack of access to resources, opportunities, and basic rights. The chapter explores how certain communities, such as Scheduled Castes (SCs), Scheduled Tribes (STs), and religious minorities, face discrimination and are pushed to the margins of society. It explains the historical and social reasons behind marginalisation and highlights the efforts made by the government and social movements to uplift these communities through affirmative actions like reservations and laws against discrimination. The chapter emphasizes the importance of creating an inclusive society where every individual has equal opportunities and access to justice, promoting equality and social harmony.
