His boundless wastefulness soon consumed the public treasures, and he was forced to resort to every kind of extortion to obtain money. Having exhausted Rome and Italy, in A.D. 39 he led a large army across the Alps for the purpose of plundering Gaul, where the richest citizens were put to death and their property confiscated. He was assassinated in his palace January 24, A.D. 41.

REIGN OF TIBERIUS CLAUDIUS DRUSUS NERO, A.D. 41-54.—The Emperor Claudius was the son of Drusus and Antonia, and the brother of Germanicus. He was fifty-one years old when, after the murder of Caligula, the Prætorian Guard raised him to the throne. His health had always been delicate, his mind feeble, and he had never taken any part in public affairs. His first acts were popular and mild, but, having fallen under the control of his wife Messalina, who was a monster of wickedness, he put to death many of the best of the Romans. When, however, Messalina ventured to marry C. Silius, a young Roman knight, Claudius directed her execution. He then married his niece Agrippina, who prevailed upon him to set aside his son Britannicus, and to adopt her own son Nero, who was now destined for the throne. Nero was educated by the philosopher Seneca, together with Burrus Afranius, præfect of the Prætorians. Claudius, however, becoming suspicious of the designs of his wife, she resolved upon his death. Locusta, a noted poisoner, was hired to prepare a dish of poisoned mushrooms, of which Claudius ate: but the poison not proving fatal, the physician Xenophon forced a larger quantity into his throat, and he died October 13, A.D. 54.

Claudius was fond of letters, and wrote memoirs of his own time and histories in Greek of Etruria and of Carthage. He also made various useful laws, and carried out several public works of importance. He completed the Claudian aqueduct, begun by Caligula, and built a fort and light-house at Ostia, and a tunnel from Lake Lucinus to the River Liris. Colonia Agrippina (Cologne) was raised by his orders to the most important military station in Lower Germany.

In A.D. 43 a Roman army invaded Britain. Claudius himself entered that country soon after, and returned to Rome to triumph. But Vespasian, afterward emperor, together with his son Titus, overran Britain, defeated Caractacus, the brave British chieftain, and sent him and his family prisoners to Rome. Claudius, pleased with his manly conduct, gave him his liberty.

NERO, A.D. 54-68.—The first five years of the reign of Nero were marked by the mildness and equity of his government. He discouraged luxury, reduced the taxes, and increased the authority of the Senate. His two preceptors, Seneca and Burrus, controlled his mind, and restrained for a time the constitutional insanity of the Claudian race. At length, however, he sank into licentiousness, and from licentiousness to its necessary attendants, cruelty and crime. From a modest and philosophic youth, Nero became the most cruel and dissolute of tyrants. He quarreled with his mother Agrippina, who for his sake had murdered the feeble Claudius; and when she threatened to restore Britannicus to the throne, he ordered that young prince to be poisoned at an entertainment. In order to marry Poppæa Sabina, a beautiful and dissolute woman, wife of Salvius Otho, he resolved to divorce his wife Octavia, and also to murder his mother Agrippina. Under the pretense of a reconciliation, he invited Agrippina to meet him at Baiæ, where she was placed in a boat, which fell to pieces as she entered it. Agrippina swam to the shore, but was there assassinated by the orders of her son. The Roman Senate congratulated Nero upon this fearful deed, while the philosopher Seneca wrote a defense of the matricide. The philosopher, the Senate, and the emperor seem worthy of each other.

It would be impossible to enumerate all the crimes of Nero. In A.D. 64 a fire broke out in Rome, which lasted for six days, consuming the greater part of the city. Nero was supposed to have ordered the city to be fired, to obtain a clear representation of the burning of Troy, and, while Rome was in flames, amused himself by playing upon musical instruments. He sought to throw the odium of this event upon the Christians, and inflicted upon them fearful cruelties. The city was rebuilt upon an improved plan, and Nero's palace, called the Golden House, occupied a large part of the ruined capital with groves, gardens, and buildings of unequaled magnificence.

In A.D. 65 a plot was discovered in which many eminent Romans were engaged. The poet Lucan, Seneca, the philosopher and defender of matricide, together with many others, were put to death. In A.D. 67 Nero traveled to Greece, and performed on the cithara at the Olympian and Isthmian games. He also contended for the prize in singing, and put to death a singer whose voice was louder than his own. Stained with every crime of which human nature is capable, haunted by the shade of the mother he had murdered, and filled with remorse, Nero was finally dethroned by the Prætorian Guards, and died by his own hand, June 9, A.D. 68. He was the last of the Claudian family. No one remained who had an hereditary claim to the empire of Augustus, and the future emperors were selected by the Prætorian Guards or the provincial legions.

During this reign, Boadicea, the British queen, A.D. 61, revolted against the Romans and defeated several armies; but the governor, Suetonius Paulinus, conquered the insurgents in a battle in which eighty thousand Britons are said to have fallen. Boadicea, unwilling to survive her liberty, put an end to her life.

On the death of Nero, Servius Sulpicius Galba, already chosen emperor by the Prætorians and the Senate, was murdered in the Forum, January, A.D. 69. He was succeeded by Salvius Otho, the infamous friend of Nero, and the husband of Poppæa Sabina. The legions on the Rhine, however, proclaimed their own commander, A. Vitellius, emperor, and Otho's forces being defeated in a battle near Bedriacum, between Verona and Cremona, he destroyed himself.

Vitellius, the new emperor, was remarkable for his gluttony and his coarse vices. He neglected every duty of his office, and soon became universally contemptible. Vespasian, the distinguished general, who had been fighting successfully against the Jews in Palestine, was proclaimed emperor by the governor of Egypt. Leaving his son Titus to continue the war, Vespasian prepared to advance upon Rome. His brave adherent, Antonius Primus, at the head of the legions of the Danube, without any orders from Vespasian, marched into Italy and defeated the army of Vitellius. The Prætorians and the Roman populace still supported Vitellius; a fearful massacre took place in the city, and the Capitoline Temple was burned; but Antonius Primus took the Prætorian camp, and Vitellius was dragged from his palace and put to death, December 20, A.D. 69.
