Lake Kubenskoye
The area was originally populated by the Finno-Ugric peoples and then colonized by the Novgorod Republic. In the 13th century, it became a part of the Principality of Beloozero. In the 14th century, the Principality of Beloozero became a part of the Grand Duchy of Moscow; however, lands adjacent of Lake Kubenskoye remained quasi-independent until the 15th century. In 1345, the lands along Lake Kubenskoye were organized into three principalities: the Principality of Novlenskoye southwest of the lake, the Principality of Zaozyorye northeast of the lake, and the Principality of Kubena southwest of the Kubena (the area was generally known as "Kubena"). The current area of the district partially overlaps with the area of the Principality of Kubena, which only existed for a short period before merging with the Principality of Zaozyorye. Before 1447, both became a part of the Grand Duchy of Moscow as well. Some of the villages in the area were first mentioned in the 15th century, including Kadnikov, which was first mentioned in 1492.
