Siege of Zadar (998)
The siege of Zadar in 998 was part of the third Croatian–Bulgarian war and one of the last military conflicts between Croatian forces of King Svetoslav Suronja (r. 997–1000), supported by Venice and the Byzantine Empire, and the army of Emperor Samuil (r. 997–1014), who launched a large-scale Bulgarian military campaign against the Kingdom of Croatia. Samuil's army besieged the fortified city of Zadar in order to aid the king's rebel brothers Krešimir and Gojslav, who asked Samuil to come and help them to remove Svetoslav Suronja from the Croatian throne. The siege was unsuccessful and Samuil's forces withdrew in the direction of the Croatian hinterland and Bosnia, finally tracing their way back home.
