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.
Estonia joined the EURO-zone in the beginning of 2011 - and now, EURO is the official currency.
