Lucius Tarquinius Superbus
Lars Porsena was king of Clusium, at that time reputed to be one of the most powerful cities in Etruria. At the behest of the exiled king of Rome, Lucius Tarquinius Superbus, Porsena had waged war against Rome. A siege of Rome ended with a peace treaty between the two cities and Porsena departed from Rome.
