The districts of British India were key administrative units of the British Raj, or Indian Empire, serving as subdivisions of the provinces and divisions of British India. These districts, often referred to as zillas in vernacular languages, played a crucial role in the governance and administration of British India, managing local affairs such as revenue collection, law enforcement, and public works. Most districts established during the British period became the foundation for modern districts of India and districts of Pakistan after the partition of India in 1947.
