On October 26th, 1377, in the place of Mile near Visoko, the Bosnian ban Tvrtko Kotromanic crowned himself king, thereby establishing the Kingdom of Bosnia – a state that had been free, organized, and recognized even centuries earlier.
His coronation marked the peak of Bosnian statehood in the Middle Ages and symbolizes the power, independence, and identity of a country that even then knew who it was and what it represented.
It cannot be stated with certainty that it happened exactly on October 26th. According to historical sources, Tvrtko’s coronation took place between October 18th and early November 1377. Of course, October 26th is considered a possible date, but it cannot be confirmed with certainty.
The first Bosnian king was crowned by his grandfather, that is, by the bishop or head of the schismatic Bosnian Church in the place of Mile, which is today Arnautovici near Visoko. The coronation took place in the Church of St. Nicholas.
It should be reminded that historiography long claimed that Tvrtko was crowned in Mileseva near Prijepolje, but today it is considered that historical sources indicate it was in Mile.
At that time, European rulers were crowned by the Catholic and Orthodox churches. Bosnian kings, however, were crowned by the Bosnian Church, with the exception of the last king, Stjepan Tomasevic, who was crowned with a papal crown in Jajce in 1461.
Tvrtko Kotromanic came from the distinguished Bosnian Kotromanic lineage, which for decades had been building the foundations of statehood, and he came to power as ban in 1353. He based his claim to the crown on inheritance through his grandmother Jelisaveta, who was from the Nemanjic dynasty, giving him formal justification to proclaim himself king “of the Serbs and Bosnia and the Coastlands and the Western Lands.” Nevertheless, his power, reputation, and the state he ruled were undeniably Bosnian.
Tvrtko’s crown was not only a symbol of personal authority but an expression of the maturity of a state. In his time, Bosnia stretched from the Sava to the Adriatic, had its own silver and gold mines, a developed trade network, minted its own money, and was recognized by European courts. During his era, some of the most significant fortifications were built, marketplaces were renewed, and Bosnia became a center of political and cultural power in the Balkans.
Tvrtko I Kotromanic was a ruler who knew how to combine political wisdom with a sense of his people’s identity. His title was broad, but the heart of his state was and remained Bosnia. The coronation of Tvrtko I Kotromanic represents one of the most important dates in the history of Bosnian statehood, as the Bosnian banate became an equal kingdom in contemporary Europe.
This date reminds us that Bosnia and Herzegovina (BiH) has a deeply rooted tradition of statehood, independence, and its own path. Tvrtko’s legacy shows that the people of Bosnia in the 14th century already had a developed sense of freedom, unity, and state identity – values that survived all eras and changes.
On this day, 648 years ago, Bosnia crowned its king – not a foreign one, but its own, the Bosnian king Tvrtko I Kotromanic.
