Romulus sibling Remus
Traditional account
The myths concerning Romulus involve several distinct episodes and figures, including the miraculous birth and youth of Romulus and his twin brother, Remus; Remus' murder and the founding of Rome; the Rape of the Sabine Women, and the subsequent war with the Sabines; a period of joint rule with Titus Tatius; the establishment of various Roman institutions; the death or apotheosis of Romulus, and the succession of Numa Pompilius.Romulus and Remus
According to Roman mythology, Romulus and Remus were the sons of Rhea Silvia by the god Mars.  Their maternal grandfather was Numitor, the rightful king of Alba Longa, through whom the twins were descended from both the Trojan hero Aeneas, and Latinus, the king of Latium.
Before the twins' birth, Numitor's throne had been usurped by his brother, Amulius, who murdered Numitor's son or sons, and condemned Rhea Silvia to perpetual virginity by consecrating her a Vestal. When Rhea became pregnant, she asserted that she had been visited by the god Mars. Amulius imprisoned her, and upon the twins' birth, ordered that they be thrown into the Tiber. But as the river had been swollen by rain, the servants tasked with disposing of the infants could not reach its banks, and so exposed the twins beneath a fig tree at the foot of the Palatine Hill.In the traditional account, a she-wolf happened upon the twins, and suckled them until they were found by the king's herdsman, Faustulus, and his wife, Acca Larentia. The brothers grew to manhood among the shepherds and hill-folk.  After becoming involved in a conflict between the followers of Amulius and those of their grandfather Numitor, Faustulus told them of their origin. With the help of their friends, they lured Amulius into an ambush and killed him, restoring their grandfather to the throne. The princes then set out to establish a city of their own.
They returned to the hills overlooking the Tiber, the site where they had been exposed as infants. They could not agree on which hill should house the new city. When an omen to resolve the controversy failed to provide a clear indication, the conflict escalated and Romulus or one of his followers killed Remus. In a variant of the legend, the augurs favoured Romulus, who proceeded to plough a square furrow around the Palatine Hill to demarcate the walls of the future city. When Remus derisively leapt over the "walls" to show how inadequate they were against invaders, Romulus struck him down in anger. In another variant, Remus was killed during a melée, along with Faustulus.
