Why and when it was clear that India has no national father?

The concept of a "national father" is not applicable to India as it is to some other countries. The term "national father" typically refers to a prominent figure who played a significant role in the formation or independence of a nation. In the case of India, the struggle for independence was a collective effort involving numerous leaders and activists, making it difficult to attribute the title of a single "national father" to any individual.

However, there are several prominent figures who are widely regarded as key leaders in India's independence movement. Mahatma Gandhi, Jawaharlal Nehru, and Vallabhbhai Patel are often considered the architects of modern India. Gandhi's philosophy of non-violence and civil disobedience, Nehru's role as the first Prime Minister of independent India, and Patel's efforts in unifying the country after partition are highly significant.

It is important to note that the idea of a "national father" is subjective and varies from country to country. In India, the focus is more on collective leadership and the contributions of multiple individuals rather than a single figure.
