context: The population of Savonia was a migration that previously targeted sparsely populated or uninhabited areas in much of Finland. Migration began in the 14th century, reached its peak in the 16th century, when it was also taken over by the crown, and finally ended in the late 17th century. Savonians practiced birch farming, fishing and hunting, so their livelihoods required a lot of land. Cascading also required a mobile lifestyle. So the Savonians moved to areas that had previously been wilderness areas for Ottomans, Häme and Satakunta. They themselves had already established or were establishing their main industries as arable and livestock farming, so they did not have the same need or opportunity to move to the wilderness.
question: How long did the migration of the Saviors last?
