Tullius Ostilius

After the death of Numa, (according to tradition) a Roman, Tullius Ostilius was elected king.
During his reign from 672 to 640 b.C., Rome fought several wars against the nearby people.
The most important was the war against the town of Alba, caused by reciprical damages along the borders of both countries.
During that war, while the troops were fighting, it was suggested that the conflict was to be fought between champions coming from the two towns. The winner would have allowed his town to subdue the other.
That was the origin of the legendary duel between the three Curatii and three Oratii which ended with the victory of the Oratii. Consequently Alba was submitted and sometime later destroyed.
Among the Albans taken to Rome, the members of the principal families were given Roman citizenship while the others, plebeians, had no rights.
