Višeslav of Croatia
Baptismal font of Višeslav
|Reign||c. 785–c. 802|
He ruled with the support of the Pope and Byzantium. The Croats warred against the Franks during his rule and avoided defeat until 803, a year after his death. During the Siege of Trsat in the autumn of 799 between the defending forces of the Dalmatian Croatia under the leadership of Croatian duke Višeslav and the invading Frankish army of the Carolingian Empire, the Frankish commander Eric of Friuli was killed. Ultimately, his duchy did accept Frankish overlordship through the Pax Nicephori.
Višeslav left behind a baptismal font (Croatian: Višeslavova krstionica), surviving to this day, which remains an important symbol of early Croatian history and the people's conversion to Christianity. The inscription is in Latin and mentions the name of a priest named John (Ivan) who baptized people during "the time of Duke Višeslav" in the honor of John the Baptist.
