History and Demographics
Harlu was founded in 1922 after extensive demographic and industrial development in the area. A decision of creating an Evangelical Lutheran parish to the area had already been made by the Finnish Senate in 1916 when Finland was still a Grand Duchy under Russian dominion, and the parish started fully functioning in 1918 in the freshly independent Finland. The Finnish Orthodox Church didn't establish a parish in the area despite a significant amount of its members residing in the area.

Harlu had a land area of approximately 252,6 km² and its population was 7 828 (1939) with a population density of 30,99 people per km².

Harlu constituted of nine villages: Harlu (also Leppäkoski), Heinäjoki, Honkakylä, Häyskynvaara, Joensuu, Läskelä, Paussu, Tenjärvi and Vehkalahti.
