Origin of the name Finland Proper

The name Finland Proper has historical roots. In Early Middle Ages, in the area of the present-day Southern Finland was inhabited by three main tribes: the Finns, the Tavastians and the Karelians. The southwestern part of the country, where the Finns lived, was originally called simply Finland (Suomi in Finnish).

By the 17th century, the name Finland began to be used for a broader area, creating a need for a more specific name for this region. The earliest recorded terms for "Finland Proper" appeared in Latin in the 1650s as Fennigia specialiter dicta and Fennigia presse dicta. Later, in the 18th century, the Swedish terms Finland för sig sielft and Egenteliga Finland emerged. The modern Swedish name Egentliga Finland became officially recognized by the end of the century, while the Finnish equivalent, Varsinais-Suomi, was established around the 1850s.
