The 22nd Army Corps, was a tactical formation of the Imperial Russian Army based in the Grand Duchy of Finland before the beginning of the First World War. After seeing much service during the war, the corps was disbanded following the October Revolution.
In 1905, as part of the ongoing re-organisation of the Imperial Russian Army's higher-up fighting review, the 22nd Army Corps was formed with its headquarters in Helsingfors, today the Finnish capital of Helsinki. This new corps was known as the "Finnish/Finland Corps", as its troops were exclusively from the Grand Duchy of Finland, a sub-division of the Russian Empire. On formation, the new corps was assigned to the Saint Petersburg Military District, itself headquartered just over the border in the capital; Saint Petersburg.[1] [2] [3]
When the First World War began, the corps was placed under the command of the 9th Army and transferred from army to army while seeing action of the Eastern Front. In November 1917, just after the October Revolution, the corps joined the new Western Front.
In 1917, the corps transferred control to the new Russian Republic, and later that year after the October Revolution, was disbanded.
