The surroundings of lakes Urajärvi and Pyhäjärvi have been known to be exploited as wilderness since the Stone Age, although no signs of permanent habitation from the era have been found, and the area is presumed to have been entirely uninhabitated in the interim between the Stone Age and the conversion of Finland to Christianity. By the end of paganism, Iitti had gained its first permanent inhabitants first from Hauho and Vanaja, as well as later on from Hollola.[7]

The oldest village in Iitti is presumed to be Kauramaa, though several others are mentioned in documents dating to the Middle Ages. Administratively, Iitti was a chapel subordinated to the parish of Hollola until 1539, after which it became an independent parish that also included Nastola, Jaala, Valkeala and parts of Mäntyharju, by proclamation from Gustav I. At this time, Iitti had 14 villages and 89 estates.[7]

Iitti suffered greatly over the Russo-Swedish War of 1788–1790, becoming a battleground as well as a headquarters for Swedish forces. The battle of Tillolankangas was one of the bloodiest over the entire war in Finland; the Swedes' victory cemented the liberation of the villages around river Kymi. Over the course of the war, 13 villages were destroyed in Iitti.[7]
