Tarraco was inhabited in pre-Roman times by Iberians who had commercial contacts with the Greeks and Phoenicians who settled on the coast. In 217 B.C., Roman forces arrived in Tarraco with Scipio Africanus. The population became allies and friends of the Roman people and Tarraco became a supply and winter base camp during the Roman wars against the Celtiberians. When Caesar conquered supporters of Pompey in 49 B.C., Tarraco supported his army with food. The city was made Colonia Iulia Urbs Triumphalis Tarraco, probably by Caesar after his victory in Munda. In the year 27 BC, Augustus went to Spain to monitor the campaigns in Cantabria. However, due to his poor health he preferred to stay in Tarraco. He and bestowed many marks of honor on the city, among which were its honorary titles of Colonia Victrix Togata and Colonia Julia Victrix Tarraconensis. Tarraco was the capital of the Roman province Hispania Citerior and, after Augustus' reorganization of Hispania, of Hispania Tarraconensis. Tarraco is a UNESCO World heritage site.
