The first Croatian state was the Kingdom of Croatia, unified from two dukedoms in AD 925. In 1102, Croatia united with Hungary. In 1526, it became part of the Hapsburg-dominated Austrian Empire. With Austria-Hungary's defeat in World War I, Croatia reasserted its independence long enough to become part of the Kingdom of Yugoslavia. However, this relationship proved detrimental to ethnic Croats, who were persecuted at several levels by the Serbs. The Axis took advantage of the oppression of the Croats and carved out a puppet Croatian state during World War II, which was ruled by the Ustaše, a party heavily influenced by the Nazis.
After the war, Croatia was once again integrated back into the now communist Yugoslavia. With that state's disintegration at the end of the Cold War, Croatia once again became independent.
During World War II, the Independent State of Croatia was an Italian puppet regime created to help occupy Yugoslavia. In 1943, members of the the Race's Conquest Fleet, led by Drefsab, occupied the city of Split on the Adriatic coast and attempted to convince the Croatian leadership to realign itself with the Race. The attempt was foiled when Otto Skorzeny of the SS led a German force which defeats the Lizards in Split. Croatia was later annexed to the Greater German Reich.
