From what year did the Romans start their chronology?

The Romans led their chronology from 753 BC, that is, from the founding of Rome. We can say that this event was very important for the Romans. From this date, the reign of the first Roman king, Romulus, began. After him in Rome, 6 more kings ruled. In total, the reign of the kings lasted until 509 BC. Then a coup d’etat took place in Rome and the royal power was overthrown. This is how the Roman Republic was created.
