Estonians belong to the Finno-Ugric peoples, as do the Finns and the Hungarians. Archaeological research confirms the existence of human activity in the region as early as 8000 BC; by 3500 BC the principal ancestors of the Estonians had arrived from the east.
The Republic of Estonia is divided into fifteen counties (Maakonnad), which are the administrative subdivisions of the country. The first documented mentioning of Estonian political and administrative subdivisions comes from the Chronicle of Henry of Livonia, written in the 13th century during the Northern Crusades.
