Ranga was born in Nidubrolu village in Guntur district of Andhra Pradesh to a Kamma family.

[4] Upon his return to India, he started teaching as a professor of economics at Pachaiyappa's College, Madras (Chennai).

[4][5] In Oxford, Ranga was influenced by the works of H. G. Wells, Sydney Webb, Bertrand Russell, and John Stuart Mill.

[4] Ranga met Mahatma Gandhi in Madras and was so impressed that he joined the civil disobedience movement in 1929.

All of these radical developments on the peasant front culminated in the formation of the All India Kisan Sabha (AIKS) at the Lucknow session of the Indian National Congress in April 1936, with Sahajanda Saraswati elected as its first president and Ranga as a general secretary.

The Kisan Manifesto, which was released in August 1936, demanded the abolition of the zamindari system and the cancellation of rural debts.

In response to Nehru's advocacy of cooperative farming, Ranga mobilized lakhs of peasants in Machilipatnam to oppose the abolition of property rights by the state.

The threat to property rights in an increasingly socialist India galvanized a disparate set of anti-Congress leaders to come together and form the Swatantra Party.

Ranga's concern for farmers’ welfare was recognized by Nehru, who said, "As long as Rangaji is in Parliament, the Indian peasants could sleep without any worry."

Knowing fully well that opposing Pandit Nehru can be politically dangerous to me, I performed my duty in defense of my convictions.

After facing the massive defeat of his Swatantra party in the elections, Ranga rejoined the Indian National Congress and supported Indira Gandhi, to advance his goal of uplifting peasants.

[11][12] As a result, for the first time in human history, a World Constituent Assembly convened to draft and adopt the Constitution for the Federation of Earth.

[14] Prime Minister P. V. Narasimha Rao said that when Ranga died, the country lost an outstanding parliamentarian who was a champion of public causes and rural peasants.
