Sailing ships are an ancient technology, making far reaching trade like the ancient spice trade possible. With the Mongol invasion of Java cannons started to be used in naval warfare (e.g. Cetbang by the Majapahit) and by the 14th century naval artillery was employed in Europe, documented at the Battle of Arnemuiden (1338). The 15th century, beside the established seapowers of the central Indian Ocean trade, such as the maritime kingdoms of Austronesia, saw a rise in the deployment of oceans voyaging fleets (incl. carrying naval artillery) from the extreme points of the trade, such as the Ming treasure voyages or the Iberian naval ventures all the way along the African Atlantic coast and across the Atlantic Ocean, starting the Age of Discovery.
