The position of the Romans was becoming critical, for Sertorius now formed a league with the pirates of the Mediterranean. He also entered into negotiations with Mithradates, and opened correspondence with the slaves in Italy, who were rebelling. But intrigues and jealousies arose in his camp. The outcome of these was that he was treacherously murdered by Perperna at a banquet in 72, and with his death fell the Marian party in Spain. Meanwhile a dangerous enemy was threatening Italy within her own borders. In 73 a band of gladiators, under the leadership of one of their number, named SPARTACUS escaped from the training school at Capua and took up a strong position on Mount Vesuvius. They were joined by large numbers of slaves and outcasts of every description, and were soon in a position to defeat two Praetors who were sent against them. The next year they assumed the offensive; and Spartacus found himself at the head of 100,000 men. Four generals sent against him were defeated; and for two years he ravaged Italy at will, and even threatened Rome. But intestine division showed itself in his ranks; his lieutenants grew jealous of him, and his strength began to wane. In 71 the command of the war was given to CRASSUS, who finished it in six months. Spartacus fell, fighting bravely, near Brundisium. Pompey, returning from the Sertorian war in Spain, met five thousand of those who had escaped from the array of Spartacus. These he slew to a man. Crassus pointed the moral of his victory by hanging, along the road from Rome to Capua, six thousand captives whom he had taken. Mithradates meanwhile, taking advantage of the troubles at Rome, was again in arms, and in 74 LUCIUS LICINIUS LUCULLUS was sent against him. Lucullus, of plebeian birth, first distinguished himself in the Social War, where he gained the favor of Sulla, and accompanied him, as Quaestor, in his campaign against Mithradates in 88. With Cotta he was chosen to the consulship in 74. The province of Cilicia was assigned to him, Bithynia to Cotta. Mithradates invaded Bithynia, defeated Cotta, and besieged him at Chalcedon. Lucullus, after reorganizing and disciplining his army, went to the aid of his colleague, drove the king into Pontus, and defeated him at Cabira in 72, and his fleet at Tenedos in 71, compelling him to take refuge with his son-in-law, TIGRANES, King of Armenia. Lucullus endeavored to work reforms in the administration of provincial governments in the East. The revenues of the provinces were farmed out, and the measures of Lucullus were intended to protect the tax-payers against the tax-gatherers (_publicani_). His reforms met with bitter opposition at Rome, especially from the Equites, whose chief source of income was often this same tax-farming. Intrigues against him by persons sent from Rome began to create dissatisfaction among his troops. He had been a severe disciplinarian, and so it was all the easier to turn the soldiers against him.
