Adriatic Sea in the Ancient World
The Adriatic Sea, located between Italy and the Balkan Peninsula, has a rich historical significance in the ancient world. Often referred to interchangeably with the Ionian Sea, this body of water served as a vital conduit for trade, cultural exchange, and military movements among ancient civilizations, including the Romans, Greeks, and Illyrians. The northern and southern parts of the sea were later categorized as the Adriatic and Ionian Seas, respectively, with the division marked by the Straits of Otranto.
The region is notable for its impressive archaeological sites, such as the Pula Arena in Croatia, one of the best-preserved Roman amphitheaters that showcases the architectural prowess of ancient Rome. The Adriatic served not only as a route for commerce but also as a melting pot of diverse cultures and peoples, influencing the development of cities along its coastline. Today, the historical layers of the Adriatic Sea continue to be a point of interest for researchers, historians, and travelers alike, providing insight into the interconnectedness of ancient societies.

Later, it became convenient to call the northern and southern parts of this gulf the Adriatic and Ionian Seas respectively, with their division at the Straits of Otranto (although the Adriatic coast north of that point was also described as the Ionian Gulf).
