The Croatian Kingdom was a medieval state that existed from the 10th to the 12th century. It emerged as a significant political entity in the region, with its first king, Tomislav, being crowned in 925. The kingdom played a crucial role in the formation of Croatian identity and culture during this period. In 1102, the Croatian Kingdom entered a personal union with the Hungarian Kingdom, which lasted for several centuries. This union allowed for shared governance while maintaining distinct national identities. The kingdom's influence waned over time, but its legacy remains an essential part of Croatian history.
