Garibald I (also Garivald; Latin: Garibaldus; born 540) was Duke (or King) of Bavaria from 555 until 591.
Not only did this grant Garibald prestige, but it created lasting political ties between the Bavarii and the Lombards of Pannonia and Bohemia.
Sometime before 585, the Merovingian court attempted to bind Duke Garibald more closely to its interests by arranging a marriage between his daughter Theodelinda and King Childebert II of Austrasia.
[3] Authari married Theodelinda at Verona in May 589 and named his brother-in-law, Gundoald, Duke of Asti.
According to Paulus Diaconus, peace with Bavaria was restored when Childebert named Tassilo rex (king).
