Explanation:
The sense of collective belonging: Though nationalism spread through the experience of united struggle but a variety of cultural processes captured the imagination of Indians and promoted a sense of collective belonging: Use of figures or images: The identity of India came to be visually associated with the image of Bharat Mata. Devotion to the mother figure came to be seen as an evidence of one’s nationalism Indian folklore: Nationalists started recording and using folklore’s and tales, which they believed, gave a true picture of traditional culture that had been corrupted and damaged by outside forces. So preservation of these became a way to discover one’s national identity and restore a sense of price in one’s past. Use of icons and symbols in the form of flags: Carrying the tricolor flag and holding it aloft during marches became a symbol of defiance and promoted a sense of collective belonging. Reinterpretation of history: Indians began looking into the past to rediscover the glorious developments in ancient times in the field of art, science, mathematics, religion and culture, etc. This glorious time was followed by a history of decline when India got colonized, as Indian history was miserably written by the colonizers.
