Vis (; ; Latin: Issa) is a small Croatian island in the Adriatic Sea. The farthest inhabited island off the Croatian mainland, Vis has a population of 3,460 (as of 2011) and an area of . The highest point of the island is Hum which is above sea level. The island's two largest settlements are the town of Vis on the eastern side of the island (the settlement after which the island was originally named), and Komiža, on its western coast.
Once known for its thriving fishing industry in the late 19th and early 20th century, the main present-day industries on the island are agriculture and tourism. Vis town and Komiža are also seats of separate administrative municipalities which cover the entire island and nearby islets, which are both part of Split-Dalmatia County.
Vis was inhabited by the time of the Neolithic period. In the 4th century BC, the Greek tyrant of Syracuse, Dionysius the Elder, founded the colony Issa on the island. Later, it became an independent polis, and even minted its own money and founded its own colonies, the most notable of which was Aspálathos (the modern-day city of Split). In the 1st century BC, the island was held by the Liburnians. In the 4th century BC Syracusan Greeks colonised the Island. Its importance in the region ended with the first Illyro-Roman war (29-219 BC). Having sided with Pompeus during the period of civil struggles in Rome, became an "oppidum civium Romanorum" in 47 BC.
Until 1797, the island passed under the rule of the Republic of Venice. During this time large settlements developed on the coast (Comisa, now Komiža and Lissa, now Vis). Administratively, the island of Lissa was for centuries bound to the island of Lesina, now named Hvar. The Venetian influence is still recognizable in architecture, and many words in the local Croatian dialect are Venetian in origin.
After the short-lived Napoleonic Kingdom of Italy, with Italian as the official language, it passed under the rule of Austrian Empire. It maintained its Italian name of Lissa. At the end of World War I, it passed under Italian rule in the period from 1918 to 1921, according to the 1915 Treaty of London, and then was ceded to Yugoslavia following the provisions of the 1920 Treaty of Rapallo.
The sea to the north of the island was the location of two battles:
Vis was at one point the site of the general headquarters of Marshal Josip Broz Tito, the leader of the Yugoslav Partisan resistance movement. It was liberated by the Partisans under the command of Tito, and by a British flotilla, in 1941 and 1943. At the end of World War II the island returned to Yugoslavia. During the war the island was mined. Allied fighter planes were based at a small airfield that was also used for emergency landings of Allied bombers, including an American B-24 flown by George McGovern. After the war, the Yugoslav People's Army used the island as one of its main naval bases. After Croatia became independent in 1991, its navy did not reclaim most of the facilities, and the many abandoned buildings are being used for civilian purposes. In 2008, 34 mines left over from World War II were cleared from the island.
