The "Kings of Rome" refers to the legendary seven rulers who governed the city before the establishment of the Roman Republic. These kings, including Romulus, the founder of Rome, and Tarquin the Proud, the last king, are central figures in Roman mythology and history. Their reigns are characterized by significant developments in Roman society, including the establishment of laws, religious practices, and military organization. Each king contributed to the growth of Rome, with Numa Pompilius credited for introducing religious institutions and Servius Tullius known for social and political reforms. The transition from monarchy to republic marked a pivotal moment in Roman history, leading to the eventual rise of the Roman Empire.
