Orthodox Slavic nations today include the Belarusians, Bulgarians, Macedonians, Montenegrins, Russians, Serbs and Ukrainians. They inhabit three separate contiguous areas in Eastern Europe (see map), namely a big one including most of the Russian Federation plus Ukraine and Belarus, a small one in the west, the Kaliningrad oblast which is an exclave of the Russian Federation, and a medium-sized one in the south including Bulgaria and several (but not all) countries of former Yugoslavia. They stretch from the northeast in the Baltic Sea to the Carpathian and Balkan Mountains in the southeast and southwest; from the north in the Russian Federation to the southwest in North Macedonia near the Greek border. There are also major Orthodox Slavic population hubs and communities in North Asia (predominantly Siberia), the Americas (predominantly North America), and significant diaspora groups throughout the rest of the world.
