The policy of aggrandizement of the British East India Company in the British Indian region was included in the Political causes of revolt of 1857. The vows, as well as fake promises of the British East India Company, led the common people to join in a revolt against British rule in India. Apart from that, effective control over the British Indian region and regulation of several subsidiary alliances had a great impact on the Nawabs and the zamindars in India. The major loss of the political position of the native rulers also caused the revolt of 1857.
The rebellion of 1857 had an immense effect on contemporary society such as the regulation of the “Government of India Act, 1858” which banned the power of attorney in the Indian provinces, and the transfer of the power of India to the British Government without any political representative. The main reason for the failure of the revolt of 1857 was a proper administrative arrangement among the leaders, as they had no relevant military training. After the revolt, the dynamics of different British Rule were transformed forever and the annexation, as well as expansion of the power of the British East India Company, had an end. Different princely states emerged within the British Indian region and they became important for the native administration system.
