Nandigram Violence refers to the violence in Nandigram, West Bengal, India, in 2007 due to the land acquisition for a project taken up by the CPI(M)-led Government of West Bengal to create a chemical hub, a type of special economic zone (SEZ). The policy led to an emergency in the region, and 14 people died in a police shooting.

According to Criminal Investigation Department (CID) reports, the Nandigram violence saw a Maoist insurgency in the area during the protests. However the Home Secretary of West Bengal stated that the presence of Maoists could not be confirmed in Nandigram. The Central Bureau of Investigation (CBI) later exonerated the Buddhadeb Bhattacharya government of responsibility for the shootings. However, Buddhadeb Bhattacharya had said earlier "They (the opposition) have been paid back in the same coin," supporting the violence in Nandigram by his own party workers.

The Left Front (Bengali: বামফ্রন্ট; baamfront) is an alliance of political parties in the Indian state of West Bengal. It was formed in January 1977, the founding parties being the Communist Party of India (Marxist), All India Forward Bloc, the Revolutionary Socialist Party, the Marxist Forward Bloc, the Revolutionary Communist Party of India and the Biplabi Bangla Congress. Other parties joined in later years, most notably the Communist Party of India.

The Left Front ruled the state for seven consecutive terms 1977–2011, five with Jyoti Basu as Chief Minister and two under Buddhadev Bhattacharya. The CPI(M) is the dominant force in the alliance. In the 2011 West Bengal Legislative Assembly election the Left Front failed to gain a majority of seats and left office. As of 2016 Biman Bose is the Chairman of the West Bengal Left Front Committee.
