Cassius Dio,
Dio's Roman History
(1914)
“ Thus when the territory of the Albans had been raided by the Romans, both sides rushed to battle; but before fighting they effected a reconciliation and both races decided to dwell together in one city. When, however, each clung to its own city and insisted that the other should that contention but disputed about the leadership. They saw that it was impossible, on the basis of equal sovereignty, for the two peoples to form an alliance that would be safe and free from strife, owing to the inherent disposition of men to quarrel with their equals and to desire to rule others. ”
