These were the ostensible grounds of the war. The Sabines were far from forgetting that a portion of their strength had been transferred to Rome by Tatius, and that the Roman State had lately been aggrandised by the inclusion of the population of Alba; they, therefore , on their side began to look round for outside help.
Their nearest neighbour was Etruria, and, of the Etruscans, the nearest to them were the Veientines. Their past defeats were still rankling in their memories, and the Sabines, urging them to revolt, attracted many volunteers; others of the poorest and homeless classes were paid to join them. No assistance was given by the State.
With the Veientes-it is not so surprising that the other cities rendered no assistance —the truce with Rome was still held to be binding.
