One of the most salient characteristics of the newly established Commonwealth was its multiethnicity, and accordingly diversity of religious faiths and denominations. Among the peoples represented were Poles (about 50% or less of the total population), Lithuanians, Latvians, Rus' people (corresponding to today's Belarusians, Ukrainians, Russians or their East Slavic ancestors), Germans, Estonians, Jews, Armenians, Tatars and Czechs, among others, for example smaller West European groups. As for the main social segments in the early 17th century, nearly 70% of the Commonwealth's population were peasants, over 20% residents of towns, and less than 10% nobles and clergy combined. The total population, estimated at 8–10 million, kept growing dynamically until the middle of the century. The Slavic populations of the eastern lands, Rus' or Ruthenia, were solidly, except for the Polish colonizing nobility (and Polonized elements of local nobility), Eastern Orthodox, which portended future trouble for the Commonwealth.
