Croatia
In the early seventh century AD, pagan West Slavs named the Croats (where Croatia gets its name) came to live in the former province of Dalmatia when they conquered the people already living there. However, they would soon be influenced by Roman Catholic Christian missionaries who completed the process of Christianization in the early 9th century. From the time of the crowning of Tomislav in 925 as the first King of Croatia, Croatia would become its own independent Catholic kingdom until 1102, when a Hungarian prince inherited the Croatian throne. The Hungarians would rule as Kings of Croatia until the early modern period, when the last Hungarian king of Croatia Louis II was killed at the Battle of Mohacs in 1526 and the kingdom chose the Austrian Archduke Ferdinand as king the next year.
