It was first chronicled in 1234 as Grad Mersky. It gradually developed into one of the greatest salt-mining centers of Eastern Europe, eclipsing the southern town of Halych, from which it takes its name. In the 13th century, Galich was ruled by a younger brother of Alexander Nevsky and remained in his line until 1363, when the Muscovites seized the principality and ousted the ruling family to Novgorod.
