The Tebhaga Movement, a significant peasant uprising in Bengal during 1946-47, made substantial contributions to the broader peasant struggle in India by highlighting the deep-seated agrarian inequalities and mobilizing marginalized sharecroppers. The movement's name, 'Tebhaga,' literally means 'three shares,' referring to its central demand: that sharecroppers (bargadars or adhiars) should receive two-thirds of the harvest, with the landlord (jotedar) receiving one-third, instead of the prevailing 50:50 or even more exploitative 75:25 ratio.

Key Contributions:

1. Challenging Exploitative Land Tenure: The movement directly confronted the exploitative jotedar-bargadar system, which left sharecroppers in perpetual poverty and debt. By demanding a larger share of the produce, it aimed to improve the economic condition of millions of landless or land-poor peasants.

2. Mass Mobilization and Awareness: Led primarily by the Kisan Sabha (peasant wing of the Communist Party of India), the Tebhaga Movement successfully mobilized a vast number of sharecroppers, agricultural laborers, and poor peasants across various districts of Bengal. It raised their consciousness about their rights and the injustices of the existing system, fostering a sense of collective agency and solidarity among the rural poor.

3. Direct Action and Resistance: The movement adopted radical methods of direct action. Peasants physically resisted jotedars from taking their traditional half-share, often storing the harvested paddy in their own granaries (khamar) instead of the jotedar's. This direct defiance of established power structures was a powerful statement of resistance.

4. Empowerment of Marginalized Groups: The movement saw significant participation from women, particularly tribal women, who played crucial roles in organizing, resisting police, and protecting the harvested crops. It also brought together peasants from different religious and caste backgrounds, fostering a sense of shared class identity over other divisions.

5. Influence on Post-Independence Land Reforms: Although the movement was eventually suppressed, its demands and the intensity of the peasant mobilization had a lasting impact. It put immense pressure on the colonial government and, subsequently, the independent Indian government, to address agrarian issues. The Tebhaga demands influenced the framing of land reform policies in West Bengal, particularly the Bargadari Act of 1950, which legally recognized the sharecroppers' right to a larger share and provided some security of tenure, even if imperfectly implemented initially.

6. Legacy of Peasant Activism: The Tebhaga Movement became a symbol of organized peasant resistance against feudal exploitation. It inspired subsequent peasant movements and contributed to the broader discourse on land rights, social justice, and the need for radical agrarian reforms in independent India. It demonstrated the potential for collective action to challenge entrenched power structures in rural society.

In summary, the Tebhaga Movement was a pivotal moment in India's peasant struggle, not only for its specific demands but also for its success in mobilizing the rural poor, challenging oppressive land relations through direct action, and influencing future land reform legislation, thereby leaving an indelible mark on the history of agrarian movements in India.
