According to legend, the first king of Rome was Romulus, who founded the city in 753 BC upon the Palatine Hill . Seven legendary kings are said to have ruled Rome until 509 BC, when the last king was overthrown . These kings ruled for an average of 35 years . </P> <P> The kings after Romulus were not known to be dynasts and no reference is made to the hereditary principle until after the fifth king Tarquinius Priscus .
