Postage stamps and postal history of Karelia

Karelia has appeared in philately several times; first as a breakaway republic from Soviet Russia in 1922, later when Eastern Karelia was occupied by Finland during the Continuation War of 1941 to 1944, and in the post-Soviet period when provisional stamps and cinderellas were issued. Additionally, there were Zemstvo stamps used in the early 20th century on the territory of the contemporary Republic of Karelia.
