Hartola became an independent parish in 1784. It was also granted the Swedish name Gustav Adolfs. In Finnish, the parish was also known as Kustavus, Kustavuksenpitäjä and Kustaanpitäjä, but the name Hartola was still in use. By the late 1800s, Hartola had become the sole name for the parish.[3]
Joutsa was a part of Hartola until 1860, while Leivonmäki was a part of Hartola until 1880. [4]
