Olonets Karelia in the context of "Lake Onega"

Ladoga Karelia (Finnish: Laatokan Karjala, Swedish: Ladogakarelen, Russian: Ладожская Карелия, romanized: Ladožskaja Karelija, Карельское Приладожье, Karelskoje Priladožje or Северное Приладожье, Severnoje Priladožje) is a historical region of Karelia, currently largely in Russia. Today, the term refers to the part of the Republic of Karelia in the Russian Federation comprising the south-west part of the Republic, specifically Lakhdenpokhsky District, Pitkyarantsky District and Sortavala District. This region is on the northern littoral of Lake Ladoga, which borders Olonets Karelia to the East, Leningrad Oblast (Karelian Isthmus) to the south-west and the North Karelia region of Finland to the west.

Karelian Proper (Karelian Proper: varšinaiskarjala, varzinkarjala) is a supradialect of the Karelian language, which is a Finnic language. Karelian Proper is one of two or three Karelian dialects, along with Livvi-Karelian and Ludic. Karelian Proper is a direct descendent of the Old Karelian language, compared to Livvi-Karelian and Ludian supradialects which were formed through interactions between the Old Karelian and the Old Veps languages. Karelian Proper is situated in all of White Karelia and Central Karelia (parts of Olonets Karelia).
