History: World War II Photography, Finnish Defense Forces, Finland

According to the Icelandic Egil's Saga, the Norse and the (Northern) Fennic people united their forces, apparently during the 12th century, against attacks by the Karelians who - with the assistance of Novgorod (part of today's Russia) - made advances towards Northern Finland and Norway.
According to some sources, the Karelians destroyed the Swedish town of Sigtuna in 1187.
In 1251 the Finnish Karelians again fought against the Norwegians, and in 1271 the two Finnish peoples, the Kvens and the Karelians, cooperated in wars and battles against the Norwegians in Hålogaland (Haalogaland).
