Dalmatia was very important in ancient times, so among native Illyrians we can also find significant Greek and especially Roman influence. In the 1st century Dalmatia falls under Roman authority, and the centre becomes the town of Salona. With the division of the Roman Empire, Dalmatia was under Western Roman Empire and it was exposed to an intensive migration. One of the nations that came to Dalmatia were the Croats in the 7th century, who are permanently settled there ever since. Even though Dalmatia would be the core of the first Croat state, the largest towns led by Zadar were still a part of Byzantine Empire for some time. In the 10th century, Kingdom of Croatia is created and the whole area is united under the authority of Croatian kings. Middle age was an extremely turbulent time, and the authority changes between Hungarians, Venetians, Turks, and at the beginning of the modern age, Austrians. Dalmatia was for a short time in the beginning of 19th century part of French Illyrian provinces after which it returned under Habsburg Monarchy, but the national idea of Slavic and Croatian state gets stronger. After the World War I parts of Dalmatia were the subject of international conflicts of newly created states with the Kingdom of Italy. The whole Dalmatia became a part of Croatian lands after the World War II, under which it stayed with the establishment of the Republic of Croatia and after being defended in the Croatian War of Independence.
