According to longstanding Roman tradition, Romulus established the city of Rome on the Palatine Hill on April 21, 753 BCE, after a fatal dispute with his twin brother Remus.

Summary

In the misty legends of early Italy, twin brothers Romulus and Remus, raised by a she-wolf after being abandoned as infants, grew to manhood amid disputes over territory and leadership. Romulus emerged victorious after a fatal quarrel with his brother Remus. On April 21, 753 BCE, he established the city of Rome on the Palatine Hill, marking the traditional beginning of Roman civilization according to ancient Roman historians and foundation myths. The event drew settlers from surrounding tribes and laid the groundwork for what would become a sprawling republic and later empire dominating the Mediterranean world for centuries. Early Roman records and later writers like Livy preserved this foundational narrative, blending myth with the real growth of a settlement that evolved into one of history's most influential powers.

Context

In the early centuries of the first millennium BCE, the central Italian peninsula was occupied by various Italic groups, among them the Latins, whose settlements clustered near the Tiber River. Kingdoms such as Alba Longa exercised authority in the surrounding hills, their ruling families linked in later myth to the Trojan exile Aeneas and his descendants. This landscape of small polities and pastoral communities formed the setting in which Roman writers would later place their city’s origins.

What Happened

The tradition, most fully recorded by the historian Livy, describes how the infant twins Romulus and Remus, sons of the Vestal Rhea Silvia and the god Mars, survived exposure on the Tiber, were suckled by a she-wolf, and were raised by the shepherd Faustulus. As young men they overthrew the usurping king Amulius, restored their grandfather Numitor to the throne of Alba Longa, and then resolved to found a new settlement of their own.

Aftermath

Disagreement over the site and the interpretation of omens led to conflict; Remus was slain, leaving Romulus to mark the boundaries of the future city by plowing a furrow around the Palatine Hill on the day of the Parilia festival. He invited settlers from neighboring Latin communities, organized a rudimentary senate, and established the religious and military institutions that would define early Roman kingship.

Legacy

The date 753 BCE, calculated centuries later by the scholar Varro, became the fixed point from which Romans reckoned time ab urbe condita. The founding myth supplied a shared origin story that helped unify diverse populations under Roman rule and continued to shape historical writing, public festivals, and political ideology long after the monarchy gave way to republic and empire. Modern historians regard the narrative as legendary rather than factual, yet it remains central to understandings of how Romans conceived their past.

Why It Matters

The traditional founding date anchored Roman identity, calendar, and self-conception for over a millennium, influencing Western law, governance, engineering, and culture long after the empire's fall. It provided a mythic origin story that unified diverse populations under a shared Roman heritage.
