In Roman mythology,

Romulus and Remus [it] (Latin: [ˈroːmʊlʊs], [ˈrɛmʊs]) are twin brothers whose story tells of the events that led to the founding of the city of Rome and the Roman Kingdom by Romulus, following his fratricide of Remus. The image of a she-wolf suckling the twins in their infancy has been a symbol of the city of Rome and the ancient Romans since at least the 3rd century BC. Although the tale takes place before the founding of Rome around 750 BC, the earliest known written account of the myth is from the late 3rd century BC. Possible historical bases for the story, and interpretations of its local variants, are subjects of ongoing debate.

Romulus and Remus were born in Alba Longa, one of the many ancient Latin cities near the Seven hills of Rome. Their mother Rhea Silvia, also known as Ilia,^[2] was a Vestal Virgin and the daughter of former king Numitor, who had been displaced by his brother Amulius. In some sources, Rhea Silvia conceived them when the god Mars visited her in a sacred grove dedicated to him.^[3]

Seeing them as a possible threat to his rule, King Amulius ordered them to be killed and they were abandoned on the bank of the river Tiber to die. They were saved by the god Tiberinus, Father of the River, and survived with the care of others at the site of future Rome. In the best-known episode, the twins were suckled by a she-wolf in a cave now known as the Lupercal.^[4] Eventually, they were adopted by Faustulus, a shepherd. They grew up tending flocks, unaware of their true identities. Over time, they became natural leaders and attracted a company of supporters from the community.

When they were young adults, they became involved in a dispute between supporters of Numitor and Amulius. As a result, Remus was taken prisoner and brought to Alba Longa. Both his grandfather and the king suspected his true identity. Romulus, meanwhile, had organized an effort to free his brother and set out with help for the city. During this time, they learned of their past and joined forces with their grandfather to restore him to the throne. Amulius was killed and Numitor was reinstated as king of Alba. The twins set out to build a city of their own.

After arriving back in the area of the seven hills, they disagreed about the hill upon which to build. Romulus preferred the Palatine Hill, above the Lupercal; Remus preferred the Aventine Hill. When they could not resolve the dispute, they agreed to seek the gods’ approval through a contest of augury. Remus saw 6 auspicious birds, but Romulus saw 12 and claimed to have won divine approval. They disputed the result; Remus insulted Romulus’ new city and was killed, either by Romulus or by one of his supporters.^[5] Romulus then went on to found the city of Rome, its institutions, government, military, and religious traditions. He reigned for many years as its first king.
