HRE in Hungary is much later than the Mongols, and Hungary was never Russia. It was a basically-independent kingdom for a millennium or so.
From memory, it's Árpád-ház (House of Árpád) kings from 1000 to 1301, then the muddle with the HRE, then Matthias the Just (died 1490), then the Ottoman invasion/Habsburgs/Transylvanian principality, then just Habsburgs/Austria-Hungary, then after WWI there's the dismembered remnant of Hungary. WWII-1990 is the Communists, but that's a political party, not a country.
I think we need more categories.
