Klin has been mentioned in Russian chronicles since 1190s and was described by patriarch Nikon in 1317 (Никоновские хроники). Historians think its sight previously was a Baltic tribe settlement that grew into a wooden fortress of Slavic Novgorodians on the bank of the river Sestra (Sister). The town didn't evade the Mongol invasion and Ivan the Terrible ravage guard known as Oprichnina. In 1482, it was incorporated into Muscovy with the rest of the Grand Princedom of Tver. Town status was granted in 1781. Peter I prescribed the Klinians to serve as couchmen on the road between Moscow and Saint Petersburg. Thus the Klin's coat of arms acquired a post horseman tooting a horn.
