After its defeat in the First World War, <strong>it passed into Italian hands between 1918 and 1921, before finally becoming part of the former Kingdom of Yugoslavia<\/strong>, which controlled it until 1941.<\/p>\n<p><strong>During World War II, it was the only Croatian territory not occupied by the Germans<\/strong>, although it was occupied by the Italians, who conquered it in 1941. Its turbulent history changed again in 1943, when Tito's communist partisans seized Vis, making it their main base. <strong>In May 1943, the Allies built an airfield on the island, specifically at Plisko Polje<\/strong>, which served as a runway for fighters and bombers of the British Royal Air Force (RAF) and the US Army Air Forces (USAAF).<\/p>\n<p>After World War II, <strong>the Yugoslav communist dictatorship militarized the island and turned it into a major secret base<\/strong>, prohibiting access to any foreigner. This caused great hardship for the local population, who were shut out of the country. <strong>Tito's dictatorship built 30 military installations on Vis, including a secret submarine base<\/strong> \u2014an enormous number for a territory of only 90 square kilometers. The Yugoslav Armed Forces left the island on May 30, 1992, and it was ceded to Croatia. Today, the local population relies primarily on fishing and tourism.<\/p>\n<p>The always interesting YouTube channel <a href=\"https:\/\/www.youtube.com\/@AventurasEntresierras\" target=\"_blank\">Aventuras Entresierras<\/a> (which I recommend you subscribe to) <strong>has published an interesting video touring this island<\/strong>, visiting its submarine base and an abandoned coastal artillery battery (the video is in Spanish but has an English audio track, you can activate it in the player):<\/p>\n<p><iframe loading=\"lazy\" title=\"La Isla Prohibida.
