'Grandfather Väinämöinen'), born Vasily Leontievich Sidorov (Russian: Василий Сидоров), also known as Vaseli Levonen (1855 – 11 January 1942), was a Karelian ideological leader known for his role in the East Karelian uprising.

[1] Vasily Sidorov was born in 1855, in the Karelian village of Tunguda, then a part of the Russian Empire.

[3] By the end of December 1921, the Karelian rebels, supported by the White Guard, controlled a significant part of Northeast Karelia.

In response, Bolshevik leadership formed the Karelian Front led by Alexander Sedyakin, numbering around some 20,000 servicemen.

The Bolsheviks captured Ukhta, the rebel stronghold, by mid-February 1922, and the Karelian resistance was finally broken.
