POLITICAL CAUSES

Rani Laxmi Bai
a) Lord Dalhousie's policy of annexation caused an uproar among the people of India. The last Peshwa, Baji Rao's adopted son Nana Sahib was deprived of the pension his father was receiving. Rani Laxmi Bai's adopted son was not given the throne after the death of his father. To make matters worse Lord Dalhousie announced in 1849 that Bahadur Shah Zafar will not be allowed to stay in the Red Fort anymore and they were compelled to move to a place near Qutab Minar. To further worsen the situation Lord Canning announced in 1856 that with the demise of Bahadur Shah Zafar, his successor will not be allowed to use the title "king".
b) The political scheme's of the British were in question when they resorted to harsh means when dealing with the native princes. The written and oral pledges made with the princes were often disregarded by the British.
The annexation of Oudh without a reason led to a huge uprising. The proposal of taking away the title from the Mughal emperor shocked the Muslims. The annexation of Jhansi, Satara and Nagpur shocked the Hindus as they were predominantly Hindu states. The remaining Hindus and Muslims who were unaffected became insecure, lest they meet the same fate.

Queen Victoria, Empress of India
C) The myth about the superiority of the British were shattered when they were badly beaten in the first Afghan War. They were again humbled in 1855-56, when they had to face the rebellion of the Santhal tribe of Bengal and Bihar. This proved that the Indian army was quite powerful.
d) There was a rumour floated around that with the end of
the Revolt of 1857 the British Raj would come to an end. This rumour emanated
from the fact that the battle of Plassey in 1757 brought about British power
and with 1857 a century would be completed which will mark the end of British
rule.
