Caesaraugusta or Caesar Augusta was the name of the Roman city of Zaragoza, founded as a Colonia Inmune from Rome in 14 BC, possibly on December 23, on the intensely Romanized Iberian city of Salduie. Its foundation occurred in the context of the reorganization of the provinces of Hispania by Caesar Augustus after his victory in the Astur-Cantabrian wars. The new city received the name of "Colonia Caesar Augusta".
