East Karelia
East Karelia (, Karelian: "Idä-Karjala"), also rendered as Eastern Karelia or Russian Karelia, is a name for the part of Karelia that since the Treaty of Stolbova in 1617 has remained Eastern Orthodox under Russian supremacy. It is separated from the western part of Karelia, called "Finnish Karelia" or historically "Swedish Karelia" (before 1808). Most of East Karelia is now part of the Republic of Karelia within the Russian Federation. It consists mainly of old historical regions of Viena and Aunus.
