All India Trinamool Congress was launched in the year 1998. At that time it was known as West Bengal Trinamool Congress, (WBTC). This Indian political party is governed under the leadership of Mamata Banerjee. Mamata Banerjee`s able political conscience led her to establish a political party that would work from the grassroot level for the benefit of the people of West Bengal. Under some compelling circumstances Mamata Banerjee took the firm decision to form her anti-Stalinist party and christened it as "Trinamool Congress".

The "Trinamool Congress" adopted an exclusive symbol of "Jora Ghas Fool". The two flowers of the symbol signify the magnitude of Hindu and Muslim communities. In each flower, there are three petals that represent the symbols of nationalism, secularism and democratic socialism. It has been designed by Mamata Banerjee herself. The party`s aim clarifies its meaning from this flowery sign, which are- Nationalism, Secularism, Socialism and Democracy.

Mamata Banerjee was so committed in her crusade against Stalinism that - with the sole object of easing out the guaranteed joint fight of the Congress with the Trinamool Congress with the Trinamool Congress against the CPM - she even dissociated Trinamool Congress from the coalition of the National Democratic Alliance. The aim of the party is to make, `all round development of India in the political, economic, industrial, social, cultural, agricultural sectors and to establish India as global power keeping in view the multilingual, multifaceted, multiethnic, rich culture and heritage of India`.

Like other Indian political parties, All India Trinamool Congress also holds objectives like- to preserve the Constitution of India with avowedly strong belief and allegiance as established by law; work hard for the advancement of the principles of Nationalism, Socialism, Secularism and Democracy. By assuring social equivalence they are attempting to extinguish illiteracy, poverty and injustice and by peaceful means cause upliftment of the unfortunate, arousing of the masses, movement and participation in the lawful electoral process.
