Introduction
The influence of the Left-wing in the Indian National Congress and consequently on the struggle for independence was felt in a significant manner from the late 1920s. The Communist Party of India (CPI) was formed, by M.N. Roy, Abani Mukherji, M.P.T. Acharya, Mohammad Ali and Mohammad Shafiq, in Tashkent, Uzbekistan then in the Soviet Union in October 1920. This opened a new radical era in the anti-imperialist struggles in India.
Even though there were many radical groups functioning in India earlier the presence of a Communist state in the form of USSR greatly alarmed the British in India. The first batch of radicals reached Peshawar on 3 June 1921. They were arrested immediately under the charges of being Bolshevik (Russian communist agents) comeing to India to create troubles. A series of five conspiracy cases were instituted against them between the years 1922 and 1927. The first of these was the Peshawar Conspiracy case. This was followed by the Kanpur (Bolshevik) Conspiracy case in (1924) and the most famous, the Meerut Conspiracy case (1929). Meanwhile, the CPI was formally founded on Indian soil in 1925 in Bombay.
Various revolutionary groups were functioning then in British India, adopting socialist ideas but were not communist parties. Two revolutionaries – Bhagat Singh of the Hindustan Revolutionary Socialist Association and Kalpana Dutt of the Indian Republican Army that organised repeated raids on the Chittagong Armoury in Bengal will be the focus of the next section. The Karachi Session of the INC and its famous resolutions especially on Fundamental Rights and Duties is dealt with next. The last two topics are about the world -wide economic depression popularly known as Great Depression and its impact on India and Tamil Society and the Industrial Development registered in India in its aftermath. The Great Depression dealt a severe blow to the labour force and peasants and consequently influenced the struggle for independence in a significant way.
