lism is an ideology which shows an individual’s love & devotion towards his nation. It is actually people’s feelings for their nation as superior to all other NATIONS. The concept of nationalism in India developed at the time of the Independence movement. This was the phase when people from all the areas/caste/religion etc collectively fought against British Raj for independence. Hence nationalism can be called as collective devotion of all the nationals towards their country.Introduction of Nationalism in India:The first world war (1919) had far-reaching consequences on the entire world. After the first world war, some major MOVEMENTS broke out in India like Satyagrah & Non-co-operation movement. This has sown the seeds of nationalism in Indians. This ERA developed new social groups along with new modes of struggle. The major events like Jalianwala Bagh massacre & KHILAFAT movement had a strong impact on the people of India.Thus, their collective struggle against colonialism brought them together and they have collectively developed a strong feeling of responsibility, accountability, love, and devotion for their country. This collective feeling of the Indian people was the START of the development of Nationalism. Foundation of Indian National Congress in 1885 was the first organized expression of nationalism in India.Hope it will help you
