His father was Mir Hassan Ali and mother was Abeeda Rukaya Khatun.Mir Nisar Ali (Titu Mir) was one of the greatest freedom fighters of Bangladesh.
Titu Mir become a Hafiz of Quran and scholar in Hadith. He completed his Madrassa education at the age of 18 years.
Titu Mir was a renowned wrestler of his time. He defeated many of his contemporary boxers.
He went to Mecca in 1822 to perform Haj. There he met Saiyeed Ahmad Shaheed who inspired him to preach the true teachings of Islam and fight for the freedom of Muslims.
Upon returning home, he started his struggle against Bidaat. He united Hindu peasants against the Zaminders and the British occupiers and inspired them to fight for liberation of Bangladesh.
In 1822, Titu Mir went on a pilgrimage to Mecca, the Haj enjoined upon all Muslims, and on his return he commenced organizing the peasants of his native village against the landlords or Zamindars and the British colonialists. He also affected the 'tahband' a tube shaped garment worn around the waist, in preference to the dhoti, seen as more overtly Hindu, and enjoined his followers to do likewise.
Titu Mir opposed a number of discriminatory measures in force at that time which included taxes on the earing of beards and on mosques. The rift between Titu Mir and his followers on one side, and the local Zamindars supported by the British rulers on the other side, continued to widen, and armed conflict broke out at several places. Titu Mir had himself served a Zamindar as a 'lathial or 'lethel' a fighter with the quarterstaff, (which in Bengal is made of bamboo, not wood) and he was actively training his men in hand to hand combat and the use of the bamboo staff. This weapon in skilled hands is deadly against anything except projectile weapons.
The followers of Titu Mir, believed to have grown to 5,000 by that time, readied themselves for prolonged armed conflict, and they built their fort of bamboo at Narikelbaria, near the town of Barasat. This was surrounded by a high double curtain wall of bamboo stakes filled in with mud cladding and sun-baked.
Titu Mir declared independence from the British, and regions comprising the current districts of 24 Parganas, Nadia and Faridpur came under his control. The private armies of the Zamindars and the forces of the British met with a series of defeats at the hands of his men as a result of his strike-and-retreat guerrilla tactics.
Finally, the British forces, armed with cannon and muskets, mounted a concerted attacks on 14 November 1831, on Titu Mir and his followers.
