Fall of the Republic of Venice with Napoleon. On 10 June, the heir to the Duchy of Parma, Louis of Bourbon, and two days later, Napoleon invaded the Romagna, which belonged to the Papal States; on 23 June the Pope had to accept the French occupation of the northern Legations, allowing the French to occupy the port city of Ancona on the Adriatic Sea. The appearance of French warships in the Adriatic led Venice to renew the ancient decree that prohibited the entry of foreign fleets in the Venetian Lagoon, and informed Paris of that. Flotillas and fortifications were established along the lagoon's shores with 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.
