Southwest Finland

Southwest Finland, calqued as "Finland Proper" (; ), is a region in the southwest of Finland. It borders the regions of Satakunta, Pirkanmaa, Tavastia Proper (Kanta-Häme), Uusimaa, and Åland. The region's capital and most populous city is medieval Turku, which was known as the former capital city of Finland before Helsinki.
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.
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, the Tavastians and the Karelians. The southwestern part of the country, the province where the Finns lived, was called simply 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" being in official use at the end of the century. The Finnish term "Varsinais-Suomi" became established only around the 1850s.
