Metropolitan City of Venice had annexed Padua and Verona, and by the 16th century the republic included territories from the Julian Alps to Crema, Istria, Dalmatia, Cyprus and part of the Peloponnese. In 1797, Napoleon invaded the Republic and, following the Treaty of Campo Formio, it was ceded to Austria. After the final defeat of Napoleon, the Austrian Empire founded a province of Venice on the Adriatic. In 2015 this was converted to the current Metropolitan City. Facing east on the Northern Adriatic Sea, the Metropolitan City is bordered to the northeast by the Province of Udine and Province of Pordenone, south by the
Gulf of Aden of Berbera", named after the ancient Somali port city of Berbera on the south side of the gulf. However, as the city of Aden grew during the colonial era, the name of "Gulf of Aden" was popularized. The waterway is part of the important Suez Canal shipping route between the Mediterranean Sea and the Arabian Sea in the Indian Ocean, with 21,000 ships crossing the gulf annually. The name of the Gulf was inspired by the former British Crown Colony city of Aden, now part of Yemen. The Somali names are Gacanka Cadmeed or Gacanka Berbera.
