Cause → Event → Consequence
The Carolingian Empire under Charlemagne pursued an expansionist campaign along its southeastern frontier, seeking to bring Dalmatian Croatia under Frankish control. Eric of Friuli led an invasion force into Liburnia, advancing on the border town of Tarsatica as part of broader Frankish pressure on Avar and Slavic territories.
In autumn 799, a Frankish army commanded by Eric of Friuli besieged Tarsatica, defended by Croatian forces loyal to Duke Višeslav. The defenders repelled the assault, and during the siege Eric of Friuli was killed, delivering a decisive tactical defeat to the Carolingian force.
The Croatian victory at Trsat stalled Frankish military advance into Dalmatian Croatia. Subsequent negotiations between the Franks and Byzantines from 802 to 815, alongside Charlemagne's imperial coronation, produced a stalemate, after which Dalmatian Croatia peacefully accepted a limited and nominal Frankish overlordship.
