They settled the present Setúbal peninsula along the Tagus river mouth and the lower Sardum (Sado; Kallipos in the Greek sources) river valley around the 5th Century BC, where they founded several coastal towns. The exact location of the Bardili capital Bardo remains uncertain, though the towns of Equabona/Aquabona (Coina-a-Velha), Caetobriga/Cetobriga (Monte da Rotura, near Setúbal) and Salacia (Alcácer do Sal; Iberian-type mint: Ketuvion) have been identified.
In the mid-3rd century BC the Bardili were forced to acknowledge the suzerainty of Carthage at the latter part of the century. Their history after the Second Punic War is obscure. It is almost certain that the Bardili recovered their independence, which they enjoyed for nearly a century before being included into Hispania Ulterior by the praetor Publius Licinius Crassus Dives in the wake of his campaign against the Lusitani and Celtici in 93 BC.
