Named for the Persian kings Artaxerxes. Artaxerxes I, Macrocheir (484–424 B.C.) was the younger son of Xerxes I {see planet  (7211)} and the father of Xerxes II. A peace treaty with Athens in 449 B.C. marked the end of Persian expansion, with Persia recognizing the independence of the Greek cities in Asia Minor. Artaxerxes II, Mnemon, reacquired those Greek cities and also received Cyprus in a peace treaty in 386 B.C. (M 30800) _ _.
