MEGARIS, a district of ancient Greece, in the northern part of the Isthmus of Corinth, was bounded on the S. by the Saronic Gulf, on the W. by Corinth and the Corinthian Gulf, on the N. by Boeotia, and on the N.E. by Attica. It extended along the coast for about 25 miles; and its extreme breadth was estimated by Strabo to be 120 stadia. With the exception of the "White Plain," in which Megaris stands, the district is crowded with rugged chains of hills. The Geranian Mountains extend eastward from the shores of the Corinthian Gulf, sending out offshoots through the entire country, and sinking gradually as they approach the Saronic Gulf. Originally Megaris was inhabited by Eolians and Ionians, and formed part of Attica. It subse-
quently fell under the dominion of the Dorians. As it contained no town of any importance except Megara, the history of that city is the history of the district. (See MEGARA.)
