Titus Tatius
The first three tribes are said to have been established by Romulus, the founder and first King of Rome, shortly after the foundation of the city. Following the Rape of the Sabine Women, the Sabines under Titus Tatius attacked Rome, and successfully entered the city. After fierce fighting, the Sabine women themselves interceded, stepping between their husbands and their fathers to prevent further bloodshed. Peace was concluded, with Romulus and Tatius ruling jointly, and a large Sabine population relocating to Rome; the nascent city was thus evenly divided between Latins and Sabines. At this time (traditionally 750 BC), Romulus divided the people into three tribes, known as the "Ramnes" or "Ramnenses", named after himself; the "Tities" or "Titienses", named after Titus Tatius; and the "Luceres" or "Lucerenses", whose name and origin were obscure even to the ancient historians.
