Medri Bahri (Tigrinya: ምድሪ ባሕሪ, English: Land of the Sea) or Mereb Melash (Tigrinya: መረብ ምላሽ, English: Beyond the Mereb), also known as Ma'ikele Bahr or Bahr Melash was a semi-autonomous province of the Ethiopian Empire located north of the Mareb River, in the Eritrean highlands (Kebassa) and some surrounding areas. Mereb Melash corresponds to the administrative territory ruled by the Bahr Negus (King of the Sea) in medieval times. Mereb Melash comprised the historical provinces of Hamasien and Seraye.[1][2][3]
