In 1939, Subhash Chandra Bose was elected as the President of the Congress Party. He defeated Pattabhi Sitharamayya in the election. It is important to note that Subhash Chandra Bose was a prominent leader in the Indian independence movement and played a significant role in the fight against British colonial rule. Pattabhi Sitharamayya, on the other hand, was a well-known politician within the Congress Party. Jawaharlal Nehru, Maulana Abul Kalam Azad, and VB Patel were all prominent leaders in the Congress Party, but Bose emerged victorious in the election against Sitharamayya. This election marked an important milestone in the political career of Subhash Chandra Bose and reflected the growing popularity of his ideas and leadership within the Congress Party.
