Kingdom of Croatia (925–1102)

The Kingdom of Croatia was a medieval kingdom that existed from 925 to 1102. It covered most of what is now Croatia and much of Bosnia and Herzegovina. For much of its history, it was an independent country, ruled by its own kings from the Trpimirović dynasty. The kingdom often faced challenges from nearby powers like the Bulgarians, Byzantines, Hungarians, and Venice, especially over control of the eastern Adriatic coast.

One important part of the kingdom's history was the effort to use the Croatian language in religious services. This began in the 10th century with Bishop Gregory of Nin, though it caused some disagreement with the Pope. By the late 11th century, the kingdom grew stronger, especially under kings Peter Krešimir IV and Demetrius Zvonimir, who helped Croatia gain control of many coastal cities in Dalmatia.

In 1102, after a period of uncertainty following the death of the last Croatian king, the throne passed to King Coloman of Hungary. He was crowned in Biograd as the ruler of both Croatia and Hungary, beginning a union that would last for centuries. While Croatia kept much of its own governance, the Hungarian king held the ultimate authority. This arrangement became a topic of discussion among historians in the 19th century.

Name

The Kingdom of the Croats was the first official name of this country, but it later became known as the Kingdom of Croatia. Around the year 1060, when King Peter Krešimir IV took control of the Dalmatian city-states, the name changed to the Kingdom of Croatia and Dalmatia. This name was used in official documents and diplomacy from then on. Other names, like "Sclavonia," were also sometimes used in European records to refer to the same area.

Background

Main articles: Duchy of Croatia and Pannonian Slavs § Principality

The Slavs came to southeastern Europe in the early 7th century and set up several states, including the Duchy of Croatia. They began to follow Christianity soon after they arrived, and by the start of the 9th century, most had become Christian. The leaders of the duchy changed between two families, the Domagojević and the Trpimirović. Nearby, the Republic of Venice was a rival, and the duchy sometimes fought or made friends with the First Bulgarian Empire. At times, it was ruled by the bigger Carolingian Empire or the Byzantine Empire. In 879, Pope John VIII told Duke Branimir that he was an independent ruler.

History

Kingdom

Croatia became a kingdom around the year 925, with Tomislav as its first king. Though the exact details of his coronation are unknown, Tomislav united the Croats of Pannonia and Dalmatia under his rule. His kingdom included parts of modern-day Croatia, Bosnia and Herzegovina, and controlled eleven counties and one banate, each with a fortified royal town.

During this time, Croatia often interacted with neighboring powers like the Bulgarian Empire, the Byzantine Empire, and later, the Hungarians. Notable conflicts included battles against Bulgarian forces led by Simeon I. Despite these challenges, Croatia remained a significant power in the Balkans under Tomislav’s rule.

10th century

The 10th century brought changes to Croatian society. Local leaders were replaced by the king’s retainers, leading to the development of a feudal system. Peasants lost their free status and became serfs, which weakened Croatia’s military power.

Tomislav was followed by rulers like Trpimir II and Krešimir I, who maintained good relations with the Byzantine Empire and the Pope. However, the reign of Miroslav, who was killed in a power struggle, marked a period of weakening. His successor, Michael Krešimir II, restored order and strengthened ties with Dalmatian city-states. His wife Helen was buried in Solin, leaving a lasting legacy.

11th century

The early 11th century saw internal conflicts among the sons of Stephen Držislav, who fought for the throne. This weakness allowed Venice and the Bulgarians to encroach on Croatian lands. By 1000, Venetian forces had taken control of several coastal cities.

Krešimir IV, who ruled from 1058 to 1074, expanded Croatia to its largest extent, including parts of Dalmatia and influence over neighboring regions. His reign saw efforts to align more closely with the Roman Catholic Church, which caused some unrest but ultimately strengthened his rule.

Demetrius Zvonimir, who ruled from 1075 to 1089, is remembered for bringing peace and prosperity. He was crowned with the support of the Pope and strengthened ties with the Holy See, which helped maintain Croatia’s connection to Catholicism.

Succession crisis

After the death of Stephen II in 1091, a succession crisis led to civil war. The Croatian nobles eventually elected Petar Snačić as king in 1093. However, he was defeated and killed in 1097 by Coloman of Hungary. This led to negotiations, and in 1102, Coloman was crowned king, uniting Croatia with Hungary. The exact nature of this union remains debated, but it marked the beginning of a long period where Croatia retained some autonomy while being linked to the Hungarian crown.

Union with Hungary

When Croatia joined with Hungary, the Hungarian king wore the Croatian crown. After the old Hungarian royal family ended, a new family took over. Even though Croatia was joined with Hungary, it kept its own special government called the Sabor, made up of Croatian nobles. There was also a special leader called the ban who reported to the king. The Croatian nobles kept their land and titles. The first Hungarian king to rule Croatia kept the Sabor and stopped taxing Croatian land. Later kings kept the tradition of being crowned as kings of Croatia too, in a place called Biograd na Moru, until a king named Béla IV. Even though ruled by Hungary, Croatia stayed its own kingdom until the Austro-Hungarian Empire ended in 1918.
