Croatia Independence Day

History of Croatia Independence Day

Croatia’s main history dates back to 9 A.D. when sections of what is now Croatia were absorbed into the Roman Empire. Diocletian was the first Roman Emperor from the region, and his palace was built in Split. After his abdication in 305 A.D., this palace became his retirement residence, as well as a shelter for the last de jure Western Roman Emperor Julius Nepos, who fled Italy in the fifth century. Croats arrived in the Roman province of Dalmatia during the sixth and ninth centuries. They then established the Duchy of Croatia, which spanned parts of modern-day Croatia.

The Croats accepted Christianity between the seventh and ninth centuries, and Pope John VIII recognized Duke Branimir as Croatia’s first ruler on June 7, 879. Tomislav became the first king of Croatia in 925, taking Croatia into its golden age. This golden age ended in 1102 when Croatia was absorbed into the Hungarian empire. Although it still retained its autonomy, the ruler of Croatia (Ban) was appointed by the Hungarian King.

After World War I, in 1918, Croatia declared independence and joined the newly formed States of Slovenes, Croats, and Serbs. On December 4, 1918, they became the Kingdom of Serbs, Croats, and Slovenes. In 1921, a new constitution that legally binds the kingdom as a unified state came into effect, and Croatia lost its independence. In 1931, King Alexander changed the kingdom’s name to Yugoslavia. On June 25, 1991, after World War II, Croatia declared its independence. On October 8, 1991, the declaration came into implementation. However, that led to war between the Croatians and the Serbians. The war lasted until August 1995, with the victory going to Croatia.

In 2002, the Government of Ivica Racan moved the Croatia Independence Day to October 8, and June 25 became known as Statehood Day. However, on November 14, 2019, the Croatian Parliament moved Croatia Independence Day back to June 25, and October 8 became the Day of the Croatian Parliament.
