Awadh, also known as Oudh, was formally annexed to the British Empire in 1856. This event marked a significant turning point in the history of the region. The annexation followed a period of increasing British influence and intervention in Awadh's internal affairs. The British cited concerns about the administration and governance of the state as justification for the annexation, although many historians see this as a pretext for expanding British control and resources. The annexation was met with resistance, contributing to the larger backdrop of the Indian Rebellion of 1857.
