POMPEY THE YOUNGER (SExrus Pomptius), Roman warrior, 2d son of Pompey the Great :' b. 75 n.c.; d. 35 B.c. He accom panied his father in his flight into Egypt and after his death went to Spain, where he organ ized a force of fugitives and malcontents and demanded from the Roman Senate restitution of his father's property. The Senate granted him a large sum of money and made him com mander of the seas. He marched to Bmtic where he crushed all opposition and assumed the powers of a sovereign. Upon the formation of a second triumvirate in 43 B.c. he was pro scribed and thereupon turned pirate, waging continued war upon Rome by cutting off her supplies. He made Corsica, Sardinia and Sicily, which islands he had captured, the seat of his power, and from them sent forth his marauders. When Rome reached the point of starvation the populace compelled Antonius and Octavianus to sue for peace and a treaty most advantageous to Sextus was signed, in which he was con firmed in his occupation of Sicily, Corsica, Sar dinia and Achaia, and promised the consulship.
The war was, however, speedily resumed, and Sextus twice defeated the fleets of Octavianus, but his indecision permitted the Romans to re build their fleets and in 36 B.c he was signally defeated. He fled to Armenia, but being over taken by his enemies and deserted by his troops, he surrendered, and was put to death at Mile tus by the Roman legate, M. Titius, who wished to remove a man who might easily be the cause of a rupture between the triumvirs. He had assumed the name of Pius, because he endeav ored to avenge the death of his father and his brother, and this surname appears on many of his coins.
