Sunil Khilnani, an academic and author, explores the concept of Indian identity in his book 'The Idea of India', published in 1997, tracing its historical evolution from pre-independence times to the neoliberal shifts of the 1990s. He emphasizes the pluralistic nature of Indian identity, shaped by a history of cultural diversity and colonial influence, and critiques the simplistic narratives of nationalism. Khilnani's work highlights the complex interplay between regional and national identities, advocating for an understanding of India that celebrates its rich cultural tapestry.
