The company was granted undisputed right to free
trade in Bengal, Bihar and Orissa. It received the Zamindari of 24 Parganas.
Mir Jafar, however, fell into arrears and was forced to abdicate in favour of
his son-in-law Mir Qasim.
Mir Qasim: 1760-64
Mir Qasim ceded Burdwan, Midnapore and
Chittagong. He shifted his capital from Murshidabad to Munger.
Mir Qasim soon revolted as he was angry with the
British for misusing the dastak (free duty passes). However, having been
defeated by the British, he fled to Awadh, where he formed a confederacy with
Awadh ruler Shujauddaula and Mughal emperor Shah Alam II.
The Battle
of Buxar (1764): Mir Qasim, Shujauddaula and shah Alam II were defeated by
Munro.
Mir Jafar was again placed on the throne.
Successors
of Mir Qasim: Mir Jafar (1764-65), Mir Jafar (1764-65), Nazmuddaulah
(1765-66), saifuddaula (1766-70). Mubaraquddaula (1770-72).
On Mir Jafar’s death, his son Nazmuddaula was
placed on the throne and signed a treaty on 20th Feb., 1765 by which
the Nawab was to disband most of his army and to administer Bengal through a
Deputy Subedar nominated by the Company.
Clive conclude two separate treaties of Allahabad with Shah Alam II (12 Aug., 1765) and
Shjauddaula (16 Aug., 1765).
