According to the legend, the Kings of Rome were 7 and every citizen of Rome, children too, knows their names by heart: Romulus, Numa Pompilius, Tullus Hostilius, Ancus Martius, Tarquinius Priscus, Servius Tullius and Tarquinius Superbus. The period of Kings is from the Roma’s date of birth (April 21, 753 B.C.) to the Republic in 510 B.C. where the Patricians (the Rome rich class) expelled the tyranny and established an aristocratic commonwealth. Many archeological sites are able to show these ancient changes which have characterized the story of Rome.
