The name officially appeared after 1717, when Prince Eugene of Savoy used the island as an attack point in his re-conquest of Belgrade from the Turks. In 1741 a Constantinople convention was signed, which resulted in fixing the border between Austria and Turkey, concerning the islands in the Sava and Danube. By the convention, Turkey obtained the section of the island overlooking the Belgrade, while Austria got the other part, in the direction of Zemun and Banat. In liberating Belgrade in 1806 the rebel army headed by Karađorđe also used the island for military purposes, as the Serbian artillery with 500 soldiers was bombing the Kalemegdan fortress from there. Turkish city plan from 1863 still used the name Babalık for the island.
