It is not known exactly when human habitation began in the Cēsis area. The process of settlement began in the Mesolithic (7,600–4,500 BC) and continued in the Neolithic (4,500–1,500 BC). These people were still hunter-fishers, as indicated by the bone harpoons found by the Rivers Amata and Rauna, not far from Āraiši, dated to the 7th–5th and 3rd millennium BC. In ethnic terms, these people may have been the same original settlers, or Lapponoid and Finno-Ugric immigrants, who inhabited northern Latvia in the Stone Age. At the end of the Neolithic, Indo-European groups entered the area, regarded as the ancestors of the Baltic tribes. The beginnings of agriculture and stock-keeping are regarded as being connected with these people.
