The All India Trinamool Congress (also known as the Trinamool Congress, and abbreviated AITC, and formerly known as West Bengal Trinamool Congress) is a major political party in India led by Railway Minister Mamata Banerjee. Founded in 1997, it consisted largely of defectors from the Indian National Congress in West Bengal. The party is currently the member of the ruling United Progressive Alliance coalition.
Mamata Banerjee was expelled from Indian National Congress on 22 December, 1997. She formed her own party, the “Trinamool Congress”, which was registered with the Election Commission of India during mid-December, 1997. The Election Commission alloted to the party an exclusive symbol of Jora Ghas Phul, which symbolizes down-trodden grass-root flowers.
In 1998, just after formation, Trinamool Congress started getting huge response in West Bengal. Specially Congress workers and even Left workers joined the newly formed party. In the 1998 Lok Sabha poll, TMC won 7 seats.  One more Lok Sabha election was held just in 1999, in which Trinamool Congress managed to win 8 seats, thus increasing the tally by one.  In 2000, TMC won two important municipality elections, Kolkata Municipal Corporation Election and Bidhan Nagar Municipality election. In 2001 Bidhan Sabha election, TMC managed to win 60 seats.  In 2004 Lok Sabha election, TMC performed worst and managed to win only 1 seat.  In 2006 Bidhan Sabha election, TMC won 30 seats.
The West Bengal government wanted to start a chemical hub in Nandigram (situated in East Midnapore) by forcefully acquiring the land. In December 2006, the people of Nandigram were given notice by Haldia Development Authority (then headed by CPM leader Laxman Seth) that major portion of Nandigram would be seized and 70,000 people be evicted from their homes.  People started movement against this land acquisition and Trinamool Congress led the movement. Bhumi Uchchhed Pratirodh Committee (BUPC) was formed against land grabbing and eviction. On March 14, 2007 the police opened firing and killed 14 villagers. Many more went missing. Many sources claimed which was supported by CBI in its report, that armed CPM cadres, along with police, fired on protesters in Nandigram.  A large number of intellectuals protested on the streets and this incident gave birth of a new movement. Trinamool Congress leader Suvendu Adhikari(currently MP of Tamluk) led the movement and the movement was hugely supported by the people.
In 2009 Lok Sabha election, Trinamool Congress and its allies won 26 seats in West Bengal. 19 seats were won by TMC itself. 6 were won by INC and one more by SUCI. . Now, Trinamool Congress is the second largest party in the UPA alliance. This is the best performance of any non-left political party in West Bengal to be achieved ever since the Left Front came to power .
