This a survey of the postage stamps and postal history of the Russian Empire, the Soviet Union and the modern Russian Federation.
Records mention a system of messengers in the 10th century. Early letters were carried in the form of a roll, with a wax or lead seal; the earliest known of these seals dates from 1079, and mentions a governor Ratibor of Tmutarakan. The earliest surviving cover was sent in 1391 from La Tana (now Azov) to Venice.
By the 16th century, the postal system included 1,600 locations, and mail took 3 days to travel from Moscow to Novgorod. In 1634, a peace treaty between Russia and Poland established a route to Warsaw, becoming Russia's first regular international service.
Peter the Great enacted reforms making the postal system more uniform in its operations, and in 1714 the first general post offices opened in Saint Petersburg and Moscow. “Regular post service” was established along the Moscow and Riga routes. In February 1714, the postal service started biweekly runs from St. Petersburg to Riga; in June it started runs from St. Petersburg to Moscow. The field post office was founded in 1716, and the so-called ordinary post service in 1720, for fast conveyance of state ordinances and papers. Regular delivery of private parcels (the so-called heavy post) was organized in the 1730-40s. In 1746, parcels and private correspondence were first delivered by courier, and starting in 1781 money, too, could be delivered to one's door. The earliest known Russian postmark dates from July 1765; it is a single line reading "ST.PETERSBOVRG" (in Latin letters), but the first official recommendation to use postmarks did not come until 1781.
