Introduction:
The British control over Awadh, a princely state in India, was established in March 1858. This marked the end of the Indian Rebellion of 1857-1858, also known as the Sepoy Mutiny or the First War of Independence.

Context:
The Indian Rebellion of 1857 began in May 1857 and spread across many parts of India, including Awadh. Awadh, also known as Oudh, was a region in northern India ruled by the Nawabs. The annexation of Awadh by the British East India Company in 1856 had led to widespread discontent among the Indian soldiers (sepoys) and the general population.

British Control in Awadh:
The rebellion in Awadh was particularly significant as it was one of the major centers of resistance against British rule. The nawab of Awadh, Wajid Ali Shah, had been deposed and exiled by the British prior to the rebellion. The sepoys and local leaders in Awadh played a crucial role in organizing the uprising.

However, the rebellion was eventually suppressed by the British. British forces led by Sir Colin Campbell launched a series of military campaigns to crush the rebellion in various parts of India, including Awadh.

Key Events:
- November 1857: British forces under the command of Sir Colin Campbell successfully recaptured the city of Lucknow, the capital of Awadh, from the rebels. This marked a significant turning point in the British campaign to regain control over the region.
- January 1858: The British continued to face resistance from pockets of rebel forces in Awadh. However, their control over the region gradually strengthened as they launched further military operations to suppress the rebellion.
- March 1858: The British finally established complete control over Awadh. The rebel leaders were either captured or dispersed, and the British administration was reinstated in the region.

Conclusion:
In conclusion, Awadh was brought under the control of the British in March 1858. The rebellion in Awadh was a major challenge for the British during the Indian Rebellion of 1857-1858. However, through a series of military campaigns and the recapture of Lucknow, the British were able to regain control over the region and establish their authority.
