Union of Uzhhorod
The Union of Uzhhorod (Ukrainian: Ужгородська унія, romanized: Uzhhorodska uniiacode: ukr promoted to code: uk ; Rusyn: Ужгородьска унія, romanized: Uzhhorodska uniia), was a decision by 63 Ruthenian priests of the Orthodox Eparchy of Mukachevo (then divided between the Principality of Transylvania and Royal Hungary of the Habsburg monarchy) to join the Catholic Church made on April 24, 1646. Until rediscovery of its founding document in 2016, academics had debated the actual date of union, whether a document had been signed, and even whether the Union of Uzhhorod had even transpired at all.
