In 1838, Syed Ahmad entered the service of East India Company and went on to become a judge at a Small Causes Court in 1867, retiring from 1876. During the Indian Rebellion of 1857, he remained loyal to the British Raj and was noted for his actions in saving European lives. After the rebellion, he penned the booklet "The Causes of the Indian Mutiny" – a daring critique, at the time, of various British policies that he blamed for causing the revolt. Believing that the future of Muslims was threatened by the rigidity of their orthodox outlook, Sir Ahmad began promoting Western–style scientific education by founding modern schools and journals and organising Islamic entrepreneurs.
