Ruthenians 鲁塞尼亚人
Ruthenian (Cyrillic transliteration: Rusyn; German:Ruthene; Russian:Русины, Rusiny; Ukrainian:Русини/Руські, Rusyny/Rus'ki; Belarusian:Русіны, Rusin: Русины, Rusiny), an English-language exonym, is a historic name for Ukrainians.
Ukrainians were called as such, particularly in Poland, until World War II. Belarusians on the other hand were known as Litvins. Muscovites from the 16th century did not consider themselves Ruthenians and proudly referred to themselves as Muscovites, such as Ivan Fyodorov who was signing his works in Polish as Ioann Theodor Muscovite, typographer in Greek and Slavic (Polish:Ioannes Fedorowicz Moschus, typographus Græcus et Sclavonicus).
