*Wise old man voice*
Long, long ago, the male version of the nation always had the power and control of the nation. This is why we see so many male Nations. Their nyo!counterparts still existed and still lived, but they had no power and were not officially recognized by the Nations’ bosses as a nation, because they were women. This is why so many of the nations we see are males. The only reason we see nations like Vietnam, Belgium, Ukraine, Belarus, etc. is because their male counterpart was killed and they, by default, were given “Nation Status." The only exception is Hungary. They thought she was a boy, so she was randomly picked over Mangary to be a Nation. Now, the male and female halves of the nation split their work in two, and are both equally recognized.
