How did Illyrian shipbuilding influence the Roman fleet?

The Illyrians were highly skilled sailors and boatbuilders who developed a type of light, swift galley known as the liburnae. These vessels were of such superior design that the Romans eventually incorporated them into their own navy as a standard class of warship, which became known as the liburnian.12

Initially, the Romans were not a significant naval power and relied on copying the designs of their opponents, such as the Carthaginians, during the First Punic War. However, as the Roman navy evolved, they identified a need for lighter, more maneuverable vessels to combat piracy and escort merchant ships. The Illyrian liburnae proved ideal for these purposes. The Romans adapted the original design by adding a second bank of oars to the vessel, and by the time of the Battle of Actium in 31 bce, the liburnian had become the predominant Roman man-of-war.34
