The All India Trinamool Congress (transl. All India Grassroots Congress; abbr. AITC) 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 from 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 third-largest party in India in terms of number of MPs and MLAs, just after BJP and INC.
The party won a historic victory in the 2011 West Bengal Legislative Assembly election by defeating 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.
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 7 seats. In the next Lok Sabha election that was held in 1999, Trinamool Congress won 8 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 7 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.

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 be evicted from their homes to make way for a chemical plant. People started 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 and killed 14 villagers and many more went missing. Many sources claimed (and which was 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.

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 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 recognized 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.

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 (Bengali: মা মাটি মানুষ) 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 catalyze the movements against the establishment on multiple issues throughout the nation.
The highest decision-making body of the party is its Core Committee.
Main article: Saradha Group financial scandal
The Saradha Group financial scandal and the Rose Valley financial scandal came to light during her tenure and some of her cabinet ministers were accused of money laundering and have been incarcerated. One of her paintings was also sold to Sudipto Sen (central figure in the Saradha scam) for ₹1.8 crore (equivalent to ₹2.4 crore or US$300,000 in 2023), while 20 more of her pictures were seized from other Saradha Group shareholders. She has been criticised by opposition parties for not taking adequate steps against her own ministers who tried to cover-up their deeds. Sudipto Sen was arrested from Kashmir. The Shyamal Sen Commission, set up by the Chief Minister, was able to return ₹185 crore (equivalent to ₹294 crore or US$37 million in 2023) to the depositors. Leaders from Congress and CPI(M) like Adhir Ranjan Chowdhury, Sujan Chakraborty, Biman Bose were also accused in this scam. Despite Bankshall Court's order to investigate into this matter, no action has been taken by CBI against any of these leaders (other than TMC leaders) to date.

Main article: Narada sting operation
The Narada sting operation was carried out by Mathew Samuel in 2011 for the Indian newsmagazine Tehelka and published on Naradanews.com just before the 2016 West Bengal Assembly elections. The sting targeted high-ranking officials and politicians of Banerjee's political party All India Trinamool Congress (AITC).
During her tenure she challenged the federal system of India when she ordered the arrest of CBI officials, who arrived in Kolkata to investigate the Saradha Group financial scandal. But CBI's attempted arrest of Kolkata Police Commissioner was also an attack on federalism.
Rujira Banerjee, the wife of Abhishek Banerjee, the Lok Sabha member and national general secretary of the Trinamool Congress, appeared before the Enforcement Directorate (ED) on Thursday after being prevented from boarding a flight to the UAE earlier this week due to a "lookout" notice issued by the central organization. Rujira received a summons to appear before the organization on 8 June when she arrived at the airport. She was questioned by the ED in relation to the coal theft case last year. She had previously been questioned by the CBI in the same matter in 2021.
According to officials, as quoted by the news agency PTI, Rujira appeared before the ED in Kolkata on Thursday for questioning about the coal theft case. Rujira was being questioned by a team of five officials, including those from New Delhi. In a money-laundering case related to a West Bengal coal scam, the Supreme Court of India on Tuesday stayed a Delhi High Court decision allowing the Enforcement Directorate (ED) to question Trinamool Congress MP Abhishek Banerjee in Delhi, but allowed the investigation agency to question him in Kolkata after providing 24 hours' notice.

On the evening of August 11, Mondal was transferred from Asansol to the CBI office in Kolkata's Nizam Palace, where he is currently being questioned.
Mondal is one of Chief Minister Mamata Banerjee's most dependable aides, and he is in charge of all TMC operations in Birbhum. The ongoing cross-border cattle smuggling case, which allegedly involves a connection between BSF, Customs, and police personnel with racketeers and politicians, has come back into the spotlight as a result of the arrest of the TMC strongman.

Main article: Syndicate Raj
Before Trinamool (AITC) took office in West Bengal in 2011, the regional AITC party leaders grew significantly in strength. The leaders began requesting a portion of the funds used to construct any new buildings in the region. As time went on, various groups in various locations began to emerge and link with various local AITC leaders. The entire syndicate company prospered when AITC ultimately won the 2011 Legislative Assembly election and began their tenure.
This is for the first time we have made Bengali pride our main poll plank. Bengali pride is not just about Bengalis; it appeals to all sons of the soil," senior TMC leader and MP Sougata Roy told PTI.
The TMC has decided to counter the BJP's Hindutva majoritarian politics by invoking Bengali sub-nationalism ahead of the State Assembly polls. With Mamata Banerjee setting the tone herself, TMC leaders have started attacking the BJP as a party of 'outsiders' trying to mount an assault on Bengalis.
These crises pushed the Trinamool to declare its Bengali nativist line even more vociferously, hoping that this new narrative will break the party's free fall.
The TMC has implemented a progressive development agenda, but it has also been mired in accusations of corruption and thuggery.
The Congress alliance, led by populist Mamata Banerji, has won elections in the West Bengal state assembly.
It is a recognised State party in West Bengal, Manipur, Tripura and Arunachal Pradesh, satisfying one of the conditions of the Election Commission.
