Sevérus left two sons, both of whom he had associated with himself in the government. No sooner was he dead than they quarrelled, and the elder, CARACALLA, murdered the other with his own hand in the presence of their mother.
Caracalla was blood-thirsty and cruel. After a short reign (211-216) he was murdered by one of his soldiers. By him were begun the famous baths which bore his name, and of which extensive remains still exist. Caracalla was succeeded by MACRÍNUS, who reigned but one year, and was followed by HELIOGABALUS (218-222), a priest of the sun, a true Oriental, with but few virtues. His end was like that of his predecessors. The Praetorians revolted and murdered him.
FROM ALEXANDER SEVERUS TO THE AGE OF THE THIRTY TYRANTS (222-268).
ALEXANDER SEVÉRUS was a good man, and well educated. But he endeavored in vain to check the decline of the state. The military had become all powerful, and he could effect nothing against it. During his reign (222-235), the famous baths begun by Caracalla were finished.
Sevérus was killed in a mutiny led by MAXIMIN, who was Emperor for three years (235-238), and was then murdered by his mutinous soldiers.
GORDIAN, his successor (238-244), was also slain by his own soldiers in his camp on the Euphrates, and PHILIP (244-249) and DECIUS (249-251) both fell in battle. Under Decius was begun a persecution of the Christians severer than any that preceded it.
The next seventeen years (251-268) is a period of great confusion. Several generals in different provinces were declared Emperor. The Empire nearly fell to pieces, but finally rallied without loss of territory. Its weakness, however, was apparent to all. This period is often called the AGE OF THE THIRTY TYRANTS.
FIVE GOOD EMPERORS (268-283).
FIVE GOOD EMPERORS now ruled and revived somewhat the shattered strength of the government: CLAUDIUS (268-270); AURELIAN (270-275); TACITUS (275-276); PROBUS (276-282); and CARUS (282-283). Aurelian undertook a campaign against the famous ZENOBIA, Queen of PALMÝRA. In her he found a worthy foe, one whose political ability was rendered more brilliant by her justice and courage. Defeated in the field, she fortified herself in Palmýra, which was taken after a siege and destroyed. Zenobia was carried to Rome, where she graced the triumph of her conqueror, but was afterwards permitted to live in retirement. Aurelian was the first who built the walls of Rome in their present position.
DIOCLETIAN (284-305).
