Septimius Severus was old and infirm, but his spirit was still unsubdued. When he entered into Caledonia with his son Caracalla, he brought in his train enormous armaments. His enemies were badly armed; they carried only the short sword and the target, which their descendants in the highlands still employed during the wars of the last century. But they were skilled to take advantage of the natural defences of their country, and without being able to meet the Caledonians in a fixed battle the emperor had lost, it is said, 50,000 men before abandoning his expedition. He had carried the name and arms of the Romans so far that he had no intention of retaining the territory which he had traversed. He left there neither fortress nor garrison, but when he had returned into the subjected territory he separated it from Caledonia by a new rampart, more imposing than all those of his predecessors. For two years the legions were employed in constructing it in stone, fortifying it with towers, and surrounding it with roads. The remains of this gigantic work attest to this day the power of those who raised it. The Caledonians, however, had just attempted another invasion when the emperor, who was marching against them, died at York (211 A.D.), and his son Caracalla, compelled to hasten back to Rome to protect the safety of the empire, hurriedly concluded with the rude tribes a peace which lasted for some years.

It was not until the year 228, under the reign of Diocletian and Maximilian, that the dangers which threatened Britain again disturbed the repose of the Emperors. Her shores were threatened by Saxon and Scandinavian pirates. A commander of Belgian origin named Carausius was sent against them, who crowned his success by causing himself to be proclaimed emperor by his legions. Diocletian conferred on him the title of Cæsar. This new sovereign was assassinated at York, and succeeded in the year 297 by his minister Allectus, who himself fell soon after before the power of Constantius Chlorus. When this prince died at York, his son Constantine, proclaimed emperor by his troops, carried with him on leaving Britain a great number of the young men of the country eager to serve in his armies.

The Roman empire no longer existed. The distant seat of power had been transferred to Constantinople. The province of Britain escaped from the imperial watchfulness. It was at the same time ill defended. The Caledonians at this period had yielded their place, either in fact or in name, to the Picts, so called perhaps by the Romans on account of the colors with which they painted their bodies. Side by side with them, and often driving them back upon their own territory were the Scots, originally from Ireland, from which country they crossed over in so great a number in their little flat-bottomed boats that they finally gave their own name to the country they invaded. Under the Emperor Valentinian we find them pursuing their depredations as far as London, and driven back to their own country with great difficulty by Theodosius, father of Theodosius the Great. Before him and after his death, in the year 393, Britain presented a similar spectacle to that of the other Roman provinces. The generals who were in command there, were proclaimed emperors by their legions, assassinated by their rivals, or decapitated by order of the sovereign rulers of Rome or Constantinople, from the moment that they attempted to leave the island to extend their conquests. Every one of these attempts cost Britain a number of soldiers and contributed to weaken a race already deteriorated by foreign domination. In 420, under the Emperor Honorius, when the Empire was expiring under the attacks of the barbarians, the Britons deposing the Roman magistrates, proclaimed their independence, which was immediately recognized by the emperor. But the Britons were not in a condition to struggle against the invaders who were pressing them on all sides. Like the Roman Empire, their country was fated to fall into the hands of the barbarians.

Like the Roman Empire, however, Britain had already received the principle which was destined to save her from complete desolation. In the midst of political disorganization, and of power distributed among a hundred petty chiefs, all enemies and rivals, she had already heard the only name which has been given to men for their salvation. The gospel of Jesus Christ had been proclaimed upon her shores. At what epoch or by whom is not known. Probably Rome brought with her arms the Christian faith to the British people; the Christians were numerous in the imperial armies, and their zeal often won to Jesus Christ the souls of the vanquished. Up to the reign of Diocletian the progress of Christianity in Britain was not impeded by any severity. At that epoch (303—305) the great persecution which was raging throughout the empire extended itself to Britain. Constantius Chlorus, who was then governor, favorable though he was to the Gospel, was nevertheless unable to avoid calling around him the officers of his household and announcing to them the necessity of either relinquishing their trusts or abjuring the name of Christ. Those who were cowardly enough to prefer earthly greatness to Christian fidelity found themselves disappointed in their ambitious hopes. The general immediately deprived them of office, remarking that men faithless to their God would be equally wanting in fidelity to their emperor. But the moderation of Constantius Chlorus was insufficient to extinguish the persecuting zeal of the inferior magistrates; and the British Church soon counted its martyrs. The Christians took refuge in the forests and the hills. They were able to find brethren among the rude tribes of the north; for Tertullian tells us that, in the portion of Britain where the arms of the Romans had failed to penetrate, Jesus Christ had conquered souls. With the power of Constantine Christianity ascended the throne; the British Church was organized; she had sent three Bishops to the Council of Arles in 314; but Britain was about to undergo a new yoke: and her dawning Christianity was destined to encounter other enemies.

Chapter II.
The Rule Of The Saxons
To The Invasion Of The Danes (449—832).

Discord prevailed in Britain. The petty rival chiefs, sometimes triumphant, sometimes defeated, united in vain against the Picts and Scots, whom the Roman walls no longer impeded now that the Roman power had disappeared. In this disorder, the Britons were dwindling in numbers day by day, when Vortigern, chief of Kent, conceived the project of calling to his assistance the Saxons, a famous people who inhabited the northern coasts of Germany and Denmark and extended their power even to a portion of the territory now known as Holland. Several tribes were descended from a common origin. The Jutes, the Angles, the Saxons (properly so called) all led the life of pirates, and many a time had they suddenly appeared upon the coasts of Britain or of Gaul, scattering terror among the inhabitants, whose houses they pillaged and burnt, killing all who resisted them. For a long time they risked their lives and sported with the dangers of the sea in mere skiffs; but in 449, when Vortigern called to his aid two celebrated pirates among the Jutes, named Hengist and Horsa, the Saxon vessels were long, strongly built, and capable of carrying a considerable number of men and of wrestling with the fury of the waves. The pirates responded promptly to the appeal, and for some time they faithfully observed their engagements, driving the Picts and Scots back into their territory and fighting for Vortigern against his British enemies. It is related that the Saxon Hengist, having fortified himself at Thong-Caster, situated in the county of Lincoln, gave there a feast to King Vortigern. Hengist had sent for his daughter, the beautiful Rowena, who, bending the knee before the British sovereign, offered him the cup of welcome. Her beauty enchanted Vortigern, and he could not rest until he had obtained her hand.

Whether from a weakness for the father of his wife, or from gratitude for services, or from the impossibility of ridding himself of the allies whom he had sent for, Vortigern permitted Hengist to establish himself in the isle of Thanet; and gradually fresh vessels arrived bringing reinforcements for the foreign colony. Angles followed Jutes; and the Britons began to be anxious about these powerful neighbors. At the first quarrel swords were drawn from their scabbards. Their blades were equally good and keen; for the Britons had derived their military equipments from the Romans, and the Saxons, passionately fond of iron, attached more importance to their arms than to any other possession. But the Britons had been weakened by their old dissensions; the Saxons allied themselves with the Picts and Scots, against whom they had been originally called to fight, and several indecisive battles ended in a truce. It is even related that the two parties being assembled at a banquet at Stonehenge, on the 1st of May, Hengist cried out to the Saxons, in their language, "Draw your swords!" and, at the same moment, the long knives concealed under the garments of the Saxons were plunged into the hearts of their entertainers. Vortigern alone was spared, no doubt at the intercession of Rowena. The war began; the Britons were defeated, and Eric, son of Hengist, became in 457 the first Saxon king of the county of Kent, the Isle of Wight, and that part of the coast of Hampshire which faces that island.

The success of Hengist and Horsa naturally attracted new hordes. In the year 477 the Saxons, under the command of Ella, founded the kingdom of Sussex (South Sax), which comprised only the present county of Sussex. In the year 519 other Saxons, under the orders of Cerdic, completed the invasion of South Britain, and extended themselves from the county of Surrey, bordering upon Sussex and Kent, to the eastern extremity of England; they occupied also Surrey and all that portion of Hampshire not in the possession of the Jutes, together with Hampshire, Wiltshire, Somersetshire, and Devonshire, not even leaving to the Britons the whole of the county of Cornwall. This new kingdom took the name of Wessex (West Sax).

The invaders grew bolder. In 530 a new body of Saxons, the name of whose leader is not recorded in history, arrived, and established themselves upon the northern border of the kingdoms of Kent and Wessex, founding there the kingdom of Essex (East Sax), the importance of which was due to the Thames and London, since it comprised only the county of Essex, the small territory of Middlesex, and the southern part of the county of Herts.
