Early in his reign Tarquinius Superbus, Rome's seventh and final king, called a meeting of the Latin leaders at which he persuaded them to renew their treaty with Rome and become her allies rather than her enemies, and it was agreed that the troops of the Latins would attend at a grove sacred to the goddess Ferentina on an appointed day to form a united military force with the troops of Rome. This was done, and Tarquin formed combined units of Roman and Latin troops.Livy, Ab urbe condita, 1.50–52
