The area comprising the Southwest is largely the same as the historical province of Finland Proper, so named because it is the original home of the tribe known as the Finns proper.
Origin of the name Finland Proper
The name of Finland Proper has a historical function. In historic times, in the area of the present Southern Finland lived three tribes, which were the Finns proper, the Tavastians and the Karelians. The southwestern part of the country, the province where the Finns proper lived, was simply called Finland (Finnish: Suomi). In the 17th century the name began to be used to refer to the whole land and a specified name for the lesser Finland was required. The first notes Fennigia specialiter dicta and Fennigia presse dicta were recorded in Latin in the 1650s, and the Swedish Finland för sig sielft and Egenteliga Finland later in the 18th century. The modern form Egentliga Finland was in official use at the end of the century, and the Finnish term Varsinais-Suomi became established only around the 1850s.[3]
Geography
Southwest Finland's nature differs from other regions. The most notable biotopes are the Archipelago Sea and groves. 80% of Finland's insect species can be found in Southwest Finland.[4] There are around 20,000 islands near the coast.[5]
