 During this same time period, Dubrovnik and the surrounding area were described as a part of the Croatian (Grwasiah) entity, in one of the works by the famous Arab geographer Muhammad al-Idrisi. In his book Nuzhat al-Mushataq fi ikhtiraq al-afaq (English: Joy for those who wish to sail over the world) from 1154, he mentioned Dubrovnik as the southernmost city of "the country of Croatia and Dalmatia".
