Little Russia, also known in English as Malorussia, Little Rus', Rus' Minor, and the French equivalent Petite Russie, is a geographical and historical term used to describe Ukraine. Since 1334, Yuri II Boleslav, the ruler of the Ruthenian Kingdom of Galicia–Volhynia, signed his decrees Natus dux totius Russiæ minoris, but the expression μικρὰ Ρωσσία is found as early as 1292, in the Byzantine writer Codinus. The distinction between "Great" and "Little" Rus' probably originated among Byzantine, Greek-speaking clerics who wanted to separate the two Ruthenian ecclesiastical metropolises of Halych and Moscow.
