The correct answer is: Tirhut region.
The Revolt of 1857, also known as the Indian Rebellion of 1857, the Sepoy Mutiny, or the First War of Indian Independence, was a major uprising in India in 1857 against the rule of the British East India Company. The revolt began in Meerut, India, on 10 May 1857, and spread rapidly to other parts of northern and central India. The rebels were defeated by the British in 1858, but the revolt had a profound impact on British rule in India.
The Revolt of 1857 was primarily confined to the Tirhut region of Bihar. The Tirhut region is located in the north-central part of Bihar, and it is bounded by the Ganges River to the north, the Son River to the south, the Nepal Himalayas to the east, and the United Provinces to the west. The Tirhut region is a fertile plain, and it is home to a number of important cities, including Patna, Hajipur, and Muzaffarpur.
The Revolt of 1857 in the Tirhut region was led by a number of prominent figures, including Kunwar Singh, Amar Singh, and Pir Muhammad. Kunwar Singh was a Rajput prince from Jagdishpur, and he was one of the most important leaders of the revolt in the Tirhut region. Amar Singh was a Bhumihar Brahmin from Arrah, and he was also a prominent leader of the revolt in the Tirhut region. Pir Muhammad was a Muslim saint from Shahabad, and he was a key figure in the revolt in the Tirhut region.
The Revolt of 1857 in the Tirhut region was a major event in the history of India. The revolt had a profound impact on the British Raj, and it led to a number of important changes in the way that the British ruled India. The revolt also had a significant impact on the people of the Tirhut region, and it led to a number of important changes in the way that the people of the Tirhut region lived their lives.
