Grand Duchy of Finland.  After the Napoleonic wars, at the Congress of Vienna in 1815, the European powers settled various territorial and dynastic issues that had arisen during the course of those wars.  As part of this settlement, Finland was separated from Sweden, and awarded to Russia, which was then an absolute monarchy under the tsar.  Finland was governed separately from Russia, most importantly the Tsar was the considered only the Grand Duke of Finland, and as such, rather than an absolute monarch, he was bound by the Finnish constitutional system.

Early stamps of Finland displayed no country name.  Identification can be made by the presence of the lion, stars and crown, which were the coat of arms of the grand duchy.  Separation of individual stamps from a printed sheet of multiple stamps was facilitated by serpentine roulette, creating a unique appearance and acting as a further guide to identification.  The stamps were denominated in kopecks, which unlike Russian stamps of the period, were shown in Roman rather than in Cyrillic letters.
