How did people belonging to different communities, regions or language groups develop a sense of collective belonging?

People were united through various steps:

1. The creation of the image of Bharat Mata by Bankim Chandra Chattopadhyay created a sense of oneness among the people.
2. Through Folklore, National identity was established.
3. The creation of the Indian flag by Gandhiji created the nationalism feel among the citizens.
4. The Nationalists reminded people about the rich culture and history of our country.
