These natives, full of restlessness and fond of war - full of the spirit of the Cid and of Don Quixote - were now to be tamed and, if possible, civilized by the Romans. In a military point of view the task was not difficult. It is true that the Spaniards showed themselves, not only when behind the walls of their cities or under the leadership of Hannibal, but even when left to themselves and in the open field of battle, no contemptible opponents; with their short two-edged sword which the Romans subsequently adopted from them, and their formidable assaulting columns, they not unfrequently made even the Roman legions waver. Had they been able to submit to military discipline and to political combination, they might perhaps have shaken off the foreign yoke imposed on them. But their valour was rather that of the guerilla than of the soldier, and they were utterly void of political judgment. Thus in Spain there was no serious war, but as little was there any real peace; the Spaniards, as Caesar afterwards very justly pointed out to them, never showed themselves quiet in peace or strenuous in war. Easy as it was for a Roman general to scatter a host of insurgents, it was difficult for the Roman statesman to devise any suitable means of really pacifying and civilizing Spain. In fact, he could only deal with it by palliative measures; because the only really adequate expedient, a comprehensive Latin colonization, was not accordant with the general aim of Roman policy at this period.

The territory which the Romans acquired in Spain in the course of the second Punic war was from the beginning divided into two masses - the province formerly Carthaginian, which embraced in the first instance the present districts of Andalusia, Granada, Murcia, and Valencia, and the province of the Ebro, or the modern Arragon and Catalonia, the fixed quarters of the Roman army during the last war. Out of these territories were formed the two Roman provinces of Further and Hither Spain. The Romans sought gradually to reduce to subjection the interior corresponding nearly to the two Castiles, which they comprehended under the general name of Celtiberia, while they were content with checking the incursions of the inhabitants of the western provinces, more especially those of the Lusitanians in the modern Portugal and the Spanish Estremadura, into the Roman territory; with the tribes on the north coast, the Callaecians, Asturians, and Cantabrians, they did not as yet come into contact at all.

The territories thus won, however, could not be maintained and secured without a standing garrison, for the governor of Hither Spain had no small trouble every year with the chastisement of the Celtiberians, and the governor of the more remote province found similar employment in repelling the Lusitanians. It was needful accordingly to maintain in Spain a Roman army of four strong legions, or about 40,000 men, year after year; besides which the general levy had often to be called out in the districts occupied by Rome, to reinforce the legions. This was of great importance for two reasons: it was in Spain first, at least first on any larger scale, that the military occupation of the land became continuous; and it was there consequently that the service acquired a permanent character. The old Roman custom of sending troops only where the exigencies of war at the moment required them, and of not keeping the men called to serve, except in very serious and important wars, under arms for more than a year, was found incompatible with the retention of the turbulent and remote Spanish provinces beyond the sea; it was absolutely impossible to withdraw the troops from these, and very dangerous even to relieve them extensively. The Roman burgesses began to perceive that dominion over a foreign people is an annoyance not only to the slave, but to the master, and murmured loudly regarding the odious war-service of Spain. While the new generals with good reason refused to allow the relief of the existing corps as a whole, the men mutinied and threatened that, if they were not allowed their discharge, they would take it of their own accord.

The wars themselves, which the Romans waged in Spain, were but of a subordinate importance. They began with the very departure of Scipio[3], and continued as long as the war under Hannibal lasted. After the peace with Carthage (in 553) there was a cessation of arms in the peninsula; but only for a short time. In 557 a general insurrection broke out in both provinces; the commander of the Further province was hard pressed; the commander of Hither Spain was completely defeated, and was himself slain. It was necessary to take up the war in earnest, and although in the meantime the able praetor Quintus Minucius had mastered the first danger, the senate resolved in 559 to send the consul Marcus Cato in person to Spain. On landing at Emporiae he actually found the whole of Hither Spain overrun by the insurgents; with difficulty that seaport and one or two strongholds in the interior were still held for Rome. A pitched battle took place between the insurgents and the consular army, in which, after an obstinate conflict man against man, the Roman military skill at length decided the day with its last reserve. The whole of Hither Spain thereupon sent in its submission: so little, however, was this submission meant in earnest, that on a rumour of the consul having returned to Rome the insurrection immediately recommenced. But the rumour was false; and after Cato had rapidly reduced the communities which had revolted for the second time and sold them en masse into slavery, he decreed a general disarming of the Spaniards in the Hither province, and issued orders to all the towns of the natives from the Pyrenees to the Guadalquivir to pull down their walls on one and the same day. No one knew how far the command extended, and there was no time to come to any understanding; most of the communities complied; and of the few that were refractory not many ventured, when the Roman army soon appeared before their walls, to await its assault.

These energetic measures were certainly not without permanent effect. Nevertheless the Romans had almost every year to reduce to subjection some mountain valley or mountain stronghold in the "peaceful province", and the constant incursions of the Lusitanians into the Further province led occasionally to severe defeats of the Romans. In 563, for instance, a Roman army was obliged after heavy loss to abandon its camp, and to return by forced inarches into the more tranquil districts. It was not till after a victory gained by the praetor Lucius Aemilius Paullus in 565[4], and a second still more considerable gained by the brave praetor Gaius Calpurnius beyond the Tagus over the Lusitanians in 569, that quiet for some time prevailed. In Hither Spain the hitherto almost nominal rule of the Romans over the Celtiberian tribes was placed on a firmer basis by Quintus Fulvius Flaccus, who after a great victory over them in 573 compelled at least the adjacent cantons to submission; and especially by his successor Tiberius Gracchus (575, 576), who achieved results of a permanent character not only by his arms, by which he reduced three hundred Spanish townships, but still more by his adroitness in adapting himself to the views and habits of the simple and haughty nation. He induced Celtiberians of note to take service in the Roman army, and so created a class of dependents; he assigned land to the roving tribes, and collected them in towns - the Spanish town Graccurris preserved the Roman's name - and so imposed a serious check on their freebooter habits; he regulated the relations of the several tribes to the Romans by just and wise treaties, and so stopped, as far as possible, the springs of future rebellion. His name was held in grateful remembrance by the Spaniards, and comparative peace henceforth reigned in the land, although the Celtiberians still from time to time winced under the yoke.
