The uprising was a cumulative result of multi-dimensional grievances against British imperialist policies.
- Political Causes: Lord Dalhousie's Doctrine of Lapse (Satara 1848, Jhansi 1853, Nagpur 1854) and annexation of Awadh in 1856 on grounds of misgovernance alienated native rulers and soldiers.
- Economic Causes: Heavy land revenue systems (Zamindari, Ryotwari, Mahalwari), destruction of traditional handicrafts, and commercialization of agriculture ruined peasants and artisans.
- Socio-Religious Causes: Interference in social customs (Abolition of Sati 1829, Widow Remarriage Act 1856), activities of Christian missionaries, and the Religious Disabilities Act of 1850 created widespread panic.
- Military Causes: Racial discrimination in promotions and pay, General Service Enlistment Act of 1856 (mandatory overseas service), and the immediate trigger of the Enfield Rifle using greased cartridges.
