In this essay you will be reading and learing about the early Mesolithic from 8000 BC-6000 BC in the archipelago area of Södertörn, east central Sweden.

To be able to investigate the area I have used a qualitative method which above all includes usage of literature.   The purpose of the essay is to get a better understanding of how people used to live during the Mesolithic and also try to understand how and why they did things.
