Tremissis - Egica and Wittiza Gerunda

Egica's decision to elevate his son Wittiza as co-ruler around 698–700 was a calculated dynastic move, likely meant to secure succession after the turbulent reigns that had destabilized the Visigothic throne throughout the seventh century. Joint-reign tremisses from Gerunda — modern Girona — are among the rarer mint outputs of this co-rulership, the city sitting on the northeastern edge of the Iberian kingdom near the Pyrenean passes that would, within a decade, become the entry point for the Umayyad invasion that ended Visigothic rule entirely.
