India

The economic growth and political stability under the Mauryan Empire (322–185 BCE) stimulated sustained development of civil infrastructure in ancient India. The Mauryans developed early Indian mail service as well as public wells, rest houses, and other facilities for the public. Common chariots called Dagana were sometimes used as mail chariots in ancient India. Couriers were used militarily by kings and local rulers to deliver information through runners and other carriers. The postmaster, the head of the intelligence service, was responsible for ensuring the maintenance of the courier system. Couriers were also used to deliver personal letters.

In South India, the Wodeyar dynasty (1399–1947) of the Kingdom of Mysore used mail service for espionage purposes thereby acquiring knowledge related to matters that took place at great distances.

By the end of the 18th century, a postal system in India was in operation. Later this system underwent complete modernization when the British Raj established its control over most of India. The Post Office Act XVII of 1837 provided that the Governor-General of India in Council had the exclusive right of conveying letters by post for hire within the territories of the East India Company. The mails were available to certain officials without charge, which became a controversial privilege as the years passed. On this basis the Indian Post Office was established on October 1, 1837.
