Several causes are attributed to the Vellore Mutiny. Indian sepoys had to experience numerous difficulties when they went to serve in the Company’s army.
The sepoys were forced to serve under the Company since their earlier patrons (the native chieftains) were all disappearing from the scene. The strict discipline, practice, new weapons, new methods and uniforms were all new to the sepoys. Anything new appears to be difficult and wrong for a man who is well-settled in the old way of life for a long-time.
Sir John Cradock, the commander-in-chief, with the -approval of Lord-William Bentinck, the Governor of Madras, introduced a new from of turban, resembling a European hat. Wearing ear rings and caste marks were also prohibited.
The sepoys were asked to shave the chin and to trim the moustache. The sepoys felt that these were designed to insult them and their religious and social traditions. There was also a popular belief that this was the beginning of a process by which all of them would be converted to Christianity.
