The modern Mäntyharju municipality is on the border between the historical Tavastia, Savonia and Karelia regions. The parish of Mäntyharju was formed in 1595 out of Iitti, Sysmä, Pellosniemi (see Mikkeli, Mikkelin maalaiskunta) and Taipalsaari. Before that, there was already a chapel in the village of Kyttälä, at the time part of Iitti. After the Treaty of Turku in 1743, western Mäntyharju remained Swedish while the eastern part, including the church, was ceded to Russia. The parts were reunited in 1821, when Old Finland was added to the Grand Duchy. Pertunmaa became a separate parish in May 20th of 1924 and a municipality in 1926, also including smaller parts of Hartola and Joutsa.
