Acquainted with high-ranking British officials, Sir Syed obtained close knowledge about British colonial politics during his service at the courts. At the outbreak of the Indian rebellion, on 10 May 1857, Sir Syed was serving as the chief assessment officer at the court in Bijnor. Northern India became the scene of the most intense fighting. The conflict had left large numbers of civilians dead. Erstwhile centres of Muslim power such as Delhi, Agra, Lucknow and Kanpur were severely affected. Sir Syed was personally affected by the violence and the ending of the Mughal dynasty amongst many other long-standing kingdoms. Sir Syed and many other Muslims took this as a defeat of Muslim society. He lost several close relatives who died in the violence. Although he succeeded in rescuing his mother from the turmoil, she died in Meerut, owing to the privations she had experienced.
