The name Estonia is primarily a gender-neutral name of Slavic origin that means Land Of The East.Estonia is a country in northeast Europe bordering the Baltic Sea. The name Estonia has been connected to Aesti, first mentioned by Roman historian Tacitus around 98 AD. Some historians believe he was directly referring to Balts (i.e. not Finnic-speaking Estonians), while others have proposed that the name applied to the whole Eastern Baltic region. The Scandinavian sagas referring to Eistland were the earliest sources to use the name in its modern meaning. The toponym Estland/Eistland has been linked to Old Scandinavian eist, austr meaning "the east".
