Why is "Subaltern (postcolonialism)" trending?

Wikipedia Overview

In postcolonial studies and in critical theory, subalterns are the colonial populations who are socially, politically, and geographically excluded from the hierarchy of power of an imperial colony and from the metropolitan homeland of an empire. Antonio Gramsci coined the term subaltern to identify the cultural hegemony that excludes and displaces specific people and social groups from the socio-economic institutions of society, in order to deny their agency and voices in colonial politics. The terms subaltern and subaltern studies entered the vocabulary of post-colonial studies through the works of the Subaltern Studies Group of historians who explored the political-actor role of the common people who constitute the mass population, rather than re-explore the political-actor roles of the social and economic elites in the history of India.
