By help of this, by Etruscan influence, for the Etruscans were near neighbours of Rome, their great city of Veii being but ten miles distant, and by his own daring, the grandson of the first Tarquin became the seventh King of Rome—and the last. It is needless to tell the story of how and why he was expelled.

Though his rule was oppressive, he was able and successful. Rome became the acknowledged chief of the Latin cities; her territory was enlarged at the expense of her neighbours, the Volsci; she had the advantage of being on friendly terms with the Etrurians.

It was the bad conduct of one of his sons that caused the king's overthrow and exile. The Romans' latest experience of monarchy made them resolve to change their form of government.

Theirs was to be a free State, though much was to be done and suffered, as we shall see, before freedom was reached. There were to be two heads of the State, who should hold office for a year; they were to be called Prætors  (foremost men), a title which was changed before long into Consuls  (colleagues).

The expelled monarch was not disposed to accept the new order of things, and he lost no time in attempting to recover his throne. He had not, as had his fellow-sufferer in Greece, the son of Pisistratus, to wait for the slow movements of an Eastern king, who was hundreds of miles away. His friends were at hand, for it was, of course, to the Etrurians that he appealed for help.

His first effort, however, was made in another direction. He had friends and helpers at Rome, some who really believed that the old order of things was better than the new, and others who had profited by the royal favour in the past, and looked to profit by it in the future. Tarquin sent envoys to Rome; they were nominally to ask that his private property should be restored to him, really to communicate with a royalist party which had conspired to restore the king to his throne. The conspiracy was discovered, however, and it was punished in a way which showed how sternly resolved the chiefs of the new Republic could be to do their duty without fear or favour.

Among the guilty were the two sons of Lucius Junius Brutus, who was one of the recently appointed prætors or consuls. Brutus made no attempt to save his sons from the penalty of their crime. On the contrary, he presided at their trial, pronounced on them the sentence of death, and sat with unmoved countenance while they were scourged and beheaded.

As for the property of the banished family, it was divided among the people, who were thus bound more strongly to support the new order of things.

Not long after, the Roman army met the allies of Tarquin in the field. Before the battle began, Brutus and one of the sons of Tarquin met in single combat. Both were slain. The battle itself had no decisive result, but Tarquin certainly was no nearer than before to recovering his throne.

In the course of the following year, however, he found a more powerful friend. This was Lars Porsena, King of Clusium, and head of the great league of Etrurian cities. The Romans did not venture to meet their new enemy in the field, and they failed to hold their first line of defence. This was the Janiculum Hill on the right or Etrurian bank of the Tiber—Lars Porsena took it by storm.

Rome itself now seemed to be at his mercy, for he had only to cross the bridge which joined the Janiculum to the city. But here he was baffled by the boldness of three heroic Romans. The three, representing the three great elements in the Roman people, Latin, Sabine, and Etrurian, held the bridge till its supports were cut away, and the river thus rendered impassable. The names of all, Spurius Lartius, Titus Herminius, and Horatius Cocles (Cocles means the One-Eyed), lived for ever in the memories of their countrymen, but the third was held in especial honour. His two comrades retreated to the Roman side while the last supports of the bridge were still standing; Horatius held his place till the structure had actually fallen. Then, weakened as he was by wounds, and burdened with the weight of his armour, he leapt into the river and just succeeded in reaching the Roman bank.

Rome was safe for the time, but the prospect of the future was dark. Lars Porsena had practically command of the whole country; the food supplies were cut off, and the city, which was crowded with fugitives from the rural districts, was in danger of starvation.

A young Roman noble, Caius Mucius by name, thought of a plan, which he told to a number of his friends, of delivering his country by getting rid of its powerful enemy. He made his way into the Etrurian camp, to all appearance unarmed, but carrying a dagger concealed about his person.

The King's secretary was seated in a conspicuous place, busy in receiving applications and petitions. He was clad in a splendid robe of purple, and Mucius, thinking him to be the King, stabbed him to the heart. He was at once seized and taken before Porsena. The King threatened him with torture. Mucius replied by thrusting his right hand into the fire, which was burning hard by, and holding it there till it was consumed.

"I am not afraid of your tortures," he said, "still I will tell you the secret which you wish to extort from me. Know, then, that there are three hundred men who are as determined as I am to rid the country of its most dangerous enemy. One by one they will make the attempt, and you may feel sure that sooner or later they will succeed."

The King was so impressed with this threat that he resolved to come to terms with so determined an enemy. So he made a proposal for a treaty, and as he was willing to give up his demand that King Tarquin should be restored to his throne, the Romans gladly accepted his terms.

He was to have yet another proof of how bold a race he had to deal with. Hostages, ten boys and as many girls, were handed over to him, to be held in custody till the conditions should be fulfilled; but Clœlia, one of the girl-hostages, contrived to elude the soldiers who were guarding her, and plunged into the river. Her companions followed her example, and all reached the Roman bank in safety. The Romans, however, sent them back, and Porsena, greatly impressed by this display of courage and good faith, set the hostages at liberty, restored without ransom all the prisoners whom he had captured, and even handed over to the besieged for the relief of their distress all the stores in his camp.

These picturesque stories must not, however, hide from us the truth that Rome had, in fact, to undergo a great humiliation. One Roman writer tells us that the city was surrendered to Porsena; another informs us that among the terms of the treaty was one frequently imposed upon a conquered people—as by Sisera on the Hebrews in the days of Deborah and Barak, and by the Philistines in the time of Saul—that no iron should be used except for agricultural tools.

One more great struggle Rome had to make before her freedom was assured, and this was with her Latin kinsfolk. One of the most powerful of the Latin chiefs was Octavius Mamilius, of Tusculum, who had married a daughter of King Tarquin. The decisive battle took place at the Lake Regillus.

There we hear, for the first time, of a personage who often appears in Roman history. The consuls were superseded for a time, and a dictator whose power was absolute took their place.

One of the old champions of the bridge reappeared and slew the Latin chief. Other deeds of valour were performed; Rome was helped, so the story ran, by the presence of the twin brethren, Castor and Pollux, just as in Spanish history we hear of St. James of Compostella leading on the Christian army against the Moors. In the end the Latin army was routed. This was in 495, and two years later Tarquin died.

The city of Veii, one of the most ancient and most formidable of the enemies of Rome, seems to have taken no part in the campaigns of Porsena. This king represented an adverse party in the Etruscan League. We even find him, when he had become friendly to the Romans, gratifying them by a gift of Veientine territory. When we remember that Veii was only twelve miles distant from Rome—less than the distance that Kingston-upon-Thames is from London—we perceive what a fortunate circumstance this was. After the death of Porsena the two cities were constantly at war. It is impossible to do more than note one or two of the principal events. In 476 happened the great disaster of Cremera. It is a strange story. The Veientines, unable to withstand the Roman army in the field, took shelter within their walls, issuing forth when occasion offered to plunder and destroy.

One of the great Roman families, the Fabii, undertook to deal with the trouble. It should be their business to protect their country against these robbers. The whole clan—three hundred and six men, not one of whom, says Livy, the Senate would have deemed unfit for high command—marched out of Rome, and took up a position which commanded the hostile territory. This they held for two years with success; in the third they were lured into an ambush, and perished to a man.

Only one young lad of the Fabian race remained. Happily, he had been left in Rome, for he was to be the ancestor of a race which was to serve the country in after times. Twenty years after this the Romans determined to put an end to the perpetual annoyance of an enemy almost at their gates. They found it no easy task, even though Veii received no help from the other Etruscan cities. The siege lasted for ten years, a period of supreme importance in the history of Rome, because she then had for the first time a standing army. In the tenth year a strange phenomenon was observed. The Alban Lake rose so high as to threaten the surrounding country.

The oracle of Delphi being consulted directed that the waters should be drained off, not by the usual channel, but by distributing them over the country, and that this would bring about the capture of the city. This may mean that by making a new outlet the means of driving a mine under Veii was discovered. This seems to have been the way in which the city was taken. A band of Roman soldiers suddenly emerged in the temple of Juno, which stood on the citadel. The inhabitants made a fierce resistance, but after a while, under a promise of their lives, laid down their arms. They were sold into slavery. In such matters the age had no scruples, but the gods of the place could not be disposed of so easily. A pius excuse was therefore invented. Juno was the patron deity of the city, and one of those who had been commissioned to deal with the matter asked her "either," says Livy, "by inspiration or in jest," whether she was willing to go to Rome. Her associates declared that the image nodded assent; some went so far as to say that they heard the words, "I am willing." For some years Veii stood empty; more than once Roman citizens, discontented with their lot at home, took up their abode in it. Once at least a general migration was proposed. But there was no permanent settlement. The place fell into decay. Three centuries and a half later Propertius sang:—
