Politics of India Political parties Elections

The Trinamool Congress (TMC; transl. Grassroots Congress), officially All India Trinamool Congress, is an Indian political party that is mainly influential in the state of West Bengal. It was founded by Mamata Banerjee on 1 January 1998 as a breakaway faction of the Indian National Congress and rapidly rose to prominence in the politics of West Bengal under her leadership. Presently, it is ruling the state of West Bengal beside being the fourth-largest party in India in terms of number of MPs just after the Bharatiya Janata Party, Indian National Congress and the Samajwadi Party.

The party won a historic victory in the 2011 West Bengal Legislative Assembly election by ending the 34-year-long Left Front rule, world's longest democratically elected communist government. It has won a three-time majority in the West Bengal Legislative Assembly and has been the ruling party in West Bengal since 20 May 2011. AITC is led by Mamata Banerjee as the chairperson of the party.

History

Founding

After being a member of the Indian National Congress (INC) for over 26 years, Mamata Banerjee quit the INC and established the TMC in 1998. The official election symbol of the TMC is Jora Ghas Phul (two flowers with grass). In the 1998 Lok Sabha polls, TMC won seven seats. In the next Lok Sabha election that was held in 1999, Trinamool Congress won eight seats with BJP, thus increasing its tally by one. In 2000, TMC won the Kolkata Municipal Corporation elections.

The party initially joined the National Democratic Alliance (NDA), as part of the Vajpayee government, and was initially quite successful, winning seven seats in its first election in 1998. In the 2001 Vidhan Sabha elections, the TMC won 60 seats in alliance with the INC, becoming the principal opposition party. They suffered big losses in the 2004 Lok Sabha elections and the 2006 West Bengal Legislative Assembly election, and subsequently left the NDA.

Nandigram movement

Main article: Nandigram violence

In December 2006, the people of Nandigram were given notice by Haldia Development Authority that a major portion of Nandigram would be seized and 70,000 people evicted from their homes to make way for a chemical plant. People started a movement against this land acquisition and the TMC helped lead the movement. The Bhumi Uchchhed Pratirodh Committee ('Committee against Land Evictions'; BUPC) was formed to protest against the eviction. On 14 March 2007, the police opened fire on the protesters and killed 14 villagers and many more went missing. Many sources claimed (and the claims were supported by the Central Bureau of Investigation in its report) that armed Communist Party of India (Marxist) cadres, along with police, fired on protesters in Nandigram Many intellectuals protested in the streets and this incident gave birth to a new movement. Socialist Unity Centre of India (Communist) leader Nanda Patra led the movement. The events led to a significant backlash against the CPI(M) government, and were a major factor in the TMC's success in the elections that followed.

Post-Nandigram/Singur elections

Main article: Singur Tata Nano controversy

In the 2009 Lok Sabha election, TMC won 19 seats in West Bengal, in alliance with the Congress. They subsequently became a part of Manmohan Singh's government, with Banerjee serving as Minister of Railways.

In the 2010 Kolkata municipal election, the party won 97 out of 141 seats. It also won a majority of other municipalities.

In government

Mamata Banerjee, Chief Minister of West Bengal and chairperson of All India Trinamool Congress

In the 2011 West Bengal Legislative Assembly election, the TMC-led alliance that included the INC and SUCI(C) won 227 seats in the 294-seat legislature, defeating the incumbent Left Front government which had been in power for 34 years. TMC alone won 184 seats, enabling it to govern without an alliance. Subsequently, it won a by-election in Basirhat and two Congress MLAs switched to the TMC, giving it a total of 187 seats. Banerjee, an MP at the time, had not contested the election and had to transfer to the safe seat of Bhabanipur.

On 18 September 2012, Banerjee announced her decision to withdraw support to the UPA after the TMC's demands to undo government-instituted changes including FDI in retail, increase in the price of diesel and limiting the number of subsidised cooking gas cylinders for households, were not met.

The 2014 Lok Sabha elections saw the TMC dominate the state, winning 34 out of the 42 seats. It also qualified for national party status, as the TMC had received 6% of the vote from five different states (West Bengal, Manipur, Tripura, Jharkhand and Assam). On 2 September 2016, the Election Commission recognised TMC as a national political party.

The party was reelected in the 2016 election to a supermajority government, and Banerjee continued as chief minister.

The party won the most seats in West Bengal in the 2019 Indian general election, but suffered significant losses to the Bharatiya Janata Party, which for the first time established itself as a major force in the state. After the election, the party's status came under revision by the Election Commission of India, due to a loss in presence in most states outside West Bengal.

Banerjee's government was reelected again in the 2021 state election by an unexpectedly large margin over the BJP. Prior to the election, several high-profile TMC members such as Mukul Roy and Suvendu Adhikari had defected to the BJP. Despite the large winning margin, Banerjee was defeated by Adhikari in the Nandigram seat, where she had transferred to fight Adhikari head-on.

In the 2026 Rajya Sabha elections, the TMC nominated lawyer Menaka Guruswamy to be an MP, with her becoming India's first openly LGBTQ+ national-level member of Parliament.

Party symbols and slogans

Further information: Ma Mati Manush, Joy Bangla, and Khela Hobe

The party name and election symbol represents 'grassroots'– the name contains the Bengali word trinamool, which literally means grassroots, and the symbol is a sapling emerging from the ground. The symbol is known as Jora Ghas Phul (Bengali: grass and flower; two flowers with grass). The usage of "All India" in the party name represents the rejection of "elitist" Indian National Congress from which it broke apart from.

Ma Mati Manush () was primarily a slogan, coined by Mamata Banerjee. The term is literally translated as "Mother, Motherland and People". The slogan became very popular in West Bengal at the time of the 2011 assembly election. Mamata Banerjee wrote a Bengali book with the same title. A song was also recorded with the same title.

The slogan Joy Bangla is also officially used by Mamata Banerjee and by her party Trinamool Congress as part of attempt to create a territorial and ethnolinguistic identity for Bengalis in India. It is used in particular, as a closing remark for political speeches.

In the 2021 assembly election, the party used a song "Khela Hobe" across the state. The song was penned by Debangshu Bhattacharya, a party youth wing member. The "Khela Hobe" term has been used across India by several opposition parties and to catalyse the movements against the establishment on multiple issues throughout the nation.
