3/ Mรคrket is part of the Finnish ๐ซ๐ฎ autonomous region of ร land ๐ฆ๐ฝ (which has its own ISO code of AX, and thus also emoji flag).
Since the ร land War (part of the Crimean War) in the 1850s between the UK ๐ฌ๐ง, France ๐ซ๐ท and Russia ๐ท๐บ, ร land is politically neutral and entirely demilitarised. It has its own parliament and the sole official language of the region is Swedish.
4/ In the rest of ๐ซ๐ฎ Finland, Finnish and Swedish are both official languages.
Finnish is one of the few major non-Indo European languages spoken in Europe (other examples are Estonian, Hungarian, and Basque)
