My map is not focusing on political provinces of Romanians in 1918 or of other states where Romanians lived. I created a map who follows ethnographic and geographical regions as Romanians view them, or as they politically created them when the international situation allow them to do so. Many of these regions where lived, or still lived by Romanians and the map do not claim that those regions belong only to a nation.

I tried to exclude borders or provinces who wore a consequence of foreign rule as Bukovina, or regions who wore purely political ones, with no link to the Romanian population as Partium(many confusing Partium with Crişana). I will put ethnic data for the regions who includes parts of other states, just in case, to avoid debate(Take out „_” from the tiny url).
