Miten linnalääni määritellään?
Linnalaäni () was a state administrative area in Sweden and Finland from the Middle Ages to the beginning of modern times. Its center was a castle, and the chief was either a king or a commanding officer who enjoyed the trust of the nobility. The area administered by Linnälään generally corresponded to one province of the provincial administration. Linnalaäni was divided into municipalities and administrators. The church had its own administrative system. The feudal system that generally prevailed in Western Europe in the Middle Ages influenced the development of castle counties, but in the North the feudal system never established its position as it was in other parts of Europe. The birth of the castle fiefdoms in Finland is related to the establishment of Swedish power, and its timing is based on scattered years. The castle counties were replaced by fiefdoms created in the form of government of 1634 and the subsequent rule of the lord of the land, which were the basis for the subsequent division of counties.
