Justa (or Justasa[1] and Justasus) was elected by Samaritans as their king during the 484 AD Samaritan revolt. Following his ascent in Samaria, he moved on Caesarea, where a noteworthy Samaritan community lived.[1] There, many Christians were killed and the church of St. Procopius was destroyed.[1] Justa celebrated the victory with games in the circus.[1]
According to John Malalas, Asclepiades, the dux Palaestinae (commander of the province's Limes Arabicus troops), whose units were reinforced by the Caesarea-based Arcadiani of lestodioktes (police chief) Rheges, defeated Justa, killed him and sent his head to the Eastern Roman Emperor Zeno.[2][3]
