Ruthenian and Ruthene are exonyms of Latin origin, formerly used in Eastern and Central Europe as common ethnonyms for East Slavs, particularly during the late medieval and early modern periods. The Latin term Rutheni was used in medieval sources to describe all Eastern Slavs of the Grand Duchy of Lithuania, as an exonym for people of the former Rus', thus including ancestors of the modern Rusyns, Ukrainians and Belarusians. The use of Ruthenian and related exonyms continued through the early modern period, developing several distinctive meanings, both in terms of their regional scopes and additional religious connotations.
