Question

what was the good effect on bengal when nawab wazid ali shah was deposed by the british?

Answer 1

Wajid Ali Shah succeeded to the throne of Awadh when the kingdom was well past its heyday. The British had annexed much of the kingdom under the treaty of 1801, and had impoverished Awadh by imposing a hugely expensive, British-run army and repeated demands for loans. The independence of Awadh in name was tolerated by the British only because they still needed a buffer state between their presence in the East and South, and the remnants of the Mughal Empire to the North.

Wajid Ali Shah was most unfortunate to have ascended the throne of Oudh at a time when the British East India Company was determined to grab the coveted throne of prosperous Awadh, which was "the garden, granary, and queen-province of India"- the royal predecessors and successors of Awadh were one of the major threats to the Mughal Empire before Britain's attempt at usurping full political control in India.
