Little Russia, also known as Lesser Russia, Malorussia, or Little Rus', is a geographical and historical term used to describe Ukraine.
At the beginning of the 14th century, the patriarch of Constantinople accepted the distinction between what it called the eparchies of Megalē Rosiia (lit. 'Great Rus, Great Russia') and Mikrà Rosiia (lit. 'Little Rus, Little Russia'). The jurisdiction of the latter became the metropolis of Halych in 1303. The specific meaning of the adjectives "Great" and "Little" in this context is unclear. It is possible that terms such as "Little" and "Lesser" at the time simply meant geographically smaller and/or less populous, or having fewer eparchies. Another possibility is that it denoted a relationship similar to that between a homeland and a colony (just as "Magna Graecia" denoted a Greek colony).
