The Persian generals, Tiribazus and Orontes, invade Cyprus, with an army far larger than any King Evagoras of Cyprus could raise. However, Evagoras manages to cut off this force from being resupplied, and the starving troops rebel. However, the war then turns in the Persians' favour when Evagoras' fleet is destroyed at the Battle of Citium (Larnaca, Cyprus). Evagoras flees to Salamis, where he manages to conclude a peace which allows him to remain nominally king of Salamis, though in reality he is a vassal of the Persian king.

The district of Tusculum is pacified after a revolt against Rome and conquered. After an expression of complete submission to Rome, the people of Tusculum becomes the first "municipium cum suffragio", and thenceforth the city continues to hold the rank of a municipium.
