What was revolt of 1857

The Revolt of 1857 was one of the first wars of Indian independence against the British. This revolt can aptly be termed the first war of Indian independence against the British. Kings, peasants, tribals, landlords and we sepoys, all were dissatisfied with the British rule.
The start of the revolt was on the 29th of March, 1857, when Mangal Pandey, attacked his officers. The attack by Mangal Pandey is considered one of the first acts of what came to be known as the Great Rebellion or the Sepoy Mutiny.
The sepoys wanted an end to the British rule and make Bahadur Shah Zafar their leader. In Delhi, sepoys killed many British officers, confiscated their ammunition and set their buildings on fire. A week after the British were evicted from Delhi, a wave of mutinies began in different parts of the country. More and more regiments rebelled and joined other troops at nodal places like Kanpur, Delhi and Lucknow.
Near Kanpur, Nana Saheb and in Lucknow, Birjis Qadar and his mother Begum Hazrat Mahal, contributed a lot to the uprising. Birjis Qadar was the son of Nawab Wajid Ali Shah. In Jhansi, Rani Lakshmibai, Tantia Tope and the sepoys together fought against the British. The mutiny saw the emergence of many new leaders like Ahmadullah Shah from Faizabad, Bakht Khan from Bareilly and Kunwar Singh, from Bihar.
