What are the roles of Dr. B. R. Ambedkar, Sarojini Naidu, and Rajendra Prasad in Indian society?

B. R. Ambedkar, Sarojini Naidu, and Rajendra Prasad played a vital role in Indian society because of their contributions to Indian independence.
B.R. Ambedkar's role in Indian society can be felt today as he was an important voice in crafting India's constitution. B.R. Ambedekar was vocal in suggesting that a free India had to embrace equality in as many forms as possible. He was a fierce opponent of "untouchability," the idea that society should be stratified into higher and lower castes. He argued that an independent India should be free of caste discrimination, going as far as embedding this idea in the new nation's constitution.
Sarojini Naidu was called "the nightingale of India."   Her writing and public oration reflected her passion towards Indian freedom from British control. Naidu used her renown as an artist to become a force of political change. She was active in the Indian National Congress movement. In the 1940s, she participated in the "Quit India" movement.  Despite being jailed, she did not reject her insistence on a free and independent India.  When India achieved Independence in 1947, "the nightingale" became a part of political history as she became governor of the state of Uttar Pradesh.  She was the first woman to serve in such a capacity.
Rajendra Prasad was the first president of India.  Prasad was an important force in the movement for Indian independence.  He worked with Mahatma Gandhi as an agent of non-violent civil disobedience and took part in Gandhi's Salt March.  Like Gandhi, he was imprisoned for his political actions. However, with independence, he became India's first president. 
Indian society views Ambedkar, Naidu, and Prasad as important forces. Indian independence is due, in large part, to their contributions.  Even after achieving freedom, their commitment to the country was underscored by their public service to the fledgling republic.  In Ambedkar's insistence on banishing caste discrimination, the promises and possibilities of the world's largest democracy can be realized.  Naidu's example proved that the new nation could welcome women and men as political brokers of power. Finally, President Prasad demonstrated how civic duty is the ultimate reflection of love of country.  Each of them saw a vision for the new India, a reality that Indian society appreciates and still pursues today.
