BS, Carpathian region is Hungarian, the Hungarians are as persecuted as Russians and seeking independence as well, except you don’t hear about it in the media.
That’s quite debatable - the human/ethnic origins predate even those national names. But the simples way of putting it:
Ukraine’s territory of Zakarpattia was originally part of the Kingdom of Hungary. Disputed over by Romania, Ukraine, and Hungary, it was awarded to the newly formed Czechoslovakia before being incorporated into the Ukrainian SSR. A 1991 treaty guaranteed the rights of Hungarians in Ukraine, although dual citizenship is not officially recognized.
