AITC began as a breakaway faction of the Indian National Congress and rapidly rose to prominence in the politics of West Bengal under Banerjee's leadership. AITC ruled the state of West Bengal with Banerjee serving as chief minister from 2011 until 2026. The party first came to rule the state after defeating the Left Front in 2011 elections. Subsequently, the party won in 2016 and 2021 elections. However, it failed to gain majority in 2026 election, and was defeated by the Bharatiya Janata Party (BJP).[24] After a rebellion within the party, the name and symbol of the party was frozen. Three factions emerged from the rebellion, the Nationalist Citizens Party of India, Democratic Trinamool Congress, and Mamata All India Trinamool Congress.
History
Founding
After being a member of the Indian National Congress (INC) for over 26 years, Mamata Banerjee quit the INC and established the AITC in 1998. The official election symbol of the AITC is Jora Ghas Phul (two flowers with grass). In the 1998 Lok Sabha polls, AITC won seven seats. In the next Lok Sabha election that was held in 1999, All India Trinamool Congress won eight seats with BJP, thus increasing its tally by one.[25] In 2000, AITC won the Kolkata Municipal Corporation elections.[26]
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.[27][28] In the 2001 Vidhan Sabha elections, the AITC won 60 seats in alliance with the INC, becoming the principal opposition party.[29] They suffered big losses in the 2004 Lok Sabha elections[30] and the 2006 West Bengal Legislative Assembly election,[28][31] and subsequently left the National Democratic Alliance (NDA).
Nandigram movement
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.[32] People started a movement against this land acquisition and the AITC 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[33] 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 AITC's success in the elections that followed.[34]
Post-Nandigram/Singur elections
In the 2009 Lok Sabha election, AITC 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.[35]
In government
In the 2011 West Bengal Legislative Assembly election, the AITC-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.[36][37][38] AITC 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 AITC, 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.[39]
On 18 September 2012, Banerjee announced her decision to withdraw support to the UPA after the AITC'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.[40][41]
The 2014 Lok Sabha elections saw the AITC 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).[42][43] On 2 September 2016, the Election Commission recognised AITC as a national political party.[44]
The party was reelected in the 2016 election to a supermajority government, and Banerjee continued as chief minister.[45]
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.[46][47] 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.[48]
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 AITC 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,[49] where she had transferred to fight Adhikari head-on.[50]
In the 2024 Indian general election, the AITC's campaign was led by Abhishek Banerjee and was formally part of the Indian National Developmental Inclusive Alliance. The party won 29 seats, gaining 7. In the 2026 Rajya Sabha elections, AITC nominated lawyer Menaka Guruswamy to be an MP, with her becoming India's first openly LGBTQ+ national-level member of Parliament.[51]
2026 electoral defeat and subsequent split
In May 2026, Banerjee led the party into the 2026 West Bengal Legislative Assembly election, seeking a fourth consecutive mandate. However, her party faced a landslide defeat to the BJP, losing 135 seats. Banerjee herself was defeated by the new Chief Minister Adhikari in Bhabanipur. In a move unprecedented in Indian politics, outgoing Chief Minister Mamata Banerjee refused to resign her office despite losing her seat and a majority in the assembly as a result of the election, alleging irregularities in its conduct.[52][53][54] She vacated the office upon the dissolution of the assembly by the governor at the end of its term on 7 May 2026. Veteran AITC politician Sovandeb Chattopadhyay led the party in Opposition.
After the expulsion of Ritabrata Banerjee from AITC, rebel group MLAs joined with Ritabrata and made a split in the party from Mamata Banerjee leadership. On 3 June 2026, 60 rebel MLAs signed a letter who accepting Ritabrata as their Leader of Opposition of the West Bengal Legislative Assembly and met West Bengal Governor to claim majority in AITC.[55]
In June 2026, after the defeat in legislative election, 20 AITC Lok Sabha MPs including Yusuf Pathan, Saayoni Ghosh, Shatrughan Sinha, Bapi Halder, Mala Roy, Mitali Bag, Deepak Adhikari, Arup Chakraborty, Sharmila Sarkar, Satabdi Roy, Rachna Banerjee, Prasun Banerjee and others declared rebellion in the party and presented their written wish to join National Democratic Alliance. This group was led by Kakoli Ghosh.[56][57]
The total strength of AITC in Lok Sabha was 28, 20 MPs therefore are eligible for splitting from the party, as per Indian anti-defection laws.[58][59][60]

Party symbols and slogans
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.[92] The symbol is known as Jora Ghas Phul (Bengali: grass and flower; two flowers with grass).[93] The usage of "All India" in the party name represents the rejection of "elitist" Indian National Congress from which it broke apart from.[92]
Ma Mati Manush (Bengali: মা মাটি মানুষ) was primarily a slogan, coined by Mamata Banerjee. The term is literally translated as "Mother, Motherland and People". The slogan was used in West Bengal at the time of the 2011 assembly election. Mamata Banerjee wrote a Bengali book with the same title.[94] A song was also recorded with the same title.[95][96]
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.[97][98] It is used in particular, as a closing remark for political speeches.[99][100][101]
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.[102][103]
Frontal organisations
Trinamool Students Union
Trinamool Chhatra Parishad (abbreviated TMCP, WBTMCP or West Bengal Trinamool Chhatra Parishad) popularly known as or "TMCP" is the student wing of the Congress. As of 2026 the president is Priyanka Adhikari.[104] Notable student leaders have included Abhishek Banerjee, General Secretary AITC.
