the Hindustani word Dak or ("post"). These stamps, with a value of -anna, were in use until June 1866. The first all-India stamps were issued on 1 October 1854. Stamps issued by the East India Company The volume of mail moved by the postal system increased significantly, doubling between 1854 and 1866 and doubling again by 1871. The Indian Post Office Act, 1866 (XIV) introduced reforms by 1 May 1866 to correct some of the more obvious postal-system deficiencies and abuses. Postal-service efficiencies were also introduced. In 1863, lower rates were set for "steamer" mail to Europe at (six annas, eight pies for a -ounce letter). Lower rates were also introduced for inland mail. New regulations removed special postal privileges enjoyed by officials of the East India Company. Stamps for official use were prepared and carefully accounted for, to combat abuses by officials. In 1854 Spain had printed special stamps for official communications, but in 1866 India was the first country to adopt the expedient of overprinting "Service" on postage stamps and "Service Postage" on revenue stamps. This innovation was later widely adopted by other countries. Shortages developed, so stamps also had to be improvised. Some "Service Postage" overprinted rarities resulted from abrupt changes in postal regulations. New designs for the four-anna and six-anna-eight-pie stamps were issued in 1866. Nevertheless, there was a shortage of stamps to meet the new rates. Provisional six-anna stamps were improvised by cutting the top and bottom from a current foreign-bill revenue stamp and overprinting "Postage". India was the first country in the Commonwealth to issue airmail stamps. Post-independence stamps India attained independence on 15 August 1947. Thereafter, the Indian Posts and Telegraph Department embarked on a broad-based policy for the issuance of stamps. On 21 November 1947 the first new stamp was issued by independent India. It depicts the Indian flag with the patriots' slogan, Jai Hind ("long live India"), at the top right-hand corner. The stamp was valued at three and one-half annas. A memorial to Mahatma Gandhi was issued 15 August 1948 on the first anniversary of independence. One year later a definitive series appeared, depicting India's broad cultural heritage (primarily Hindu, Buddhist, Muslim, Sikh and Jain temples, sculptures, monuments and fortresses). A subsequent issue commemorated the beginning of the Republic of India on 26 January 1950. Definitives included a technology-and-development theme in 1955, a series depicting a map of India in
