Marcellus and Tiberius either accompanied or followed Augustus to Hispania during his campaigns against the Cantabri and Astures in the Cantabrian Wars. During the second campaign in 25 BC, Marcellus and Tiberius were military tribunes with special aedile powers. After the second campaign, Augustus discharged some of his soldiers and allowed them to found the city of "Emerita Augusta" in Lusitania (now Mérida, Spain). For the soldiers still of military age, he held games under the direction of Marcellus and Tiberius. The campaigns were a way of introducing Marcellus and Tiberius to military life and, more importantly, to the soldiery.
