In ancient times Lavinium had a close association with the nearby Laurentum. According to Livy, in the eighth century BC, when Romulus and Titus Tatius jointly ruled Rome, the ambassadors of the Laurentes came to Rome, but were beaten by Tatius' relatives. The Laurentes complained, but Tatius accorded more weight to the influence of his relatives than to the injury done the Laurentes. When Tatius afterwards visited Lavinium to celebrate an anniversary sacrifice, he was slain in a tumult. Romulus declined to go to war and instead renewed the treaty between Rome and Lavinium.
