Fall of Æthelbald
First among English scholars, first among English theologians, first among English historians, it is in the monk of Jarrow that English literature strikes its roots. In the six hundred scholars who gathered round him for instruction he is the father of our national education. In his physical treatises he is the first figure to which our science looks back. But the quiet tenor of his scholar's life was broken by the growing anarchy of Northumbria, and by threats of war from its Mercian rival. At last Æthelbald marched on a state which seemed exhausted by civil discord and ready for submission to his arms. But its king Eadberht showed himself worthy of the kings that had gone before him, and in 740 he threw back Æthelbald's attack in a repulse which not only ruined the Mercian ruler's hopes of northern conquest but loosened his hold on the south. Already goaded to revolt by exactions, the West-Saxons were roused to a fresh struggle for independence, and after twelve years of continued outbreaks the whole people mustered at Burford under the golden dragon of their race. The fight was a desperate one, but a sudden panic seized the Mercian King. He fled from the field, and a decisive victory freed Wessex from the Mercian yoke. Æthelbald's own throne seems to have been shaken; for three years later, in 757, the Mercian king was surprised and slain in a night attack by his ealdormen, and a year of confusion passed ere his kinsman Offa could avenge him on his murderers and succeed to the realm.
But though Eadberht might beat back the inroads of the Mercians and even conquer Strathclyde, before the anarchy of his own kingdom he could only fling down his sceptre and seek a refuge in the cloister of Lindisfarne. From the death of Bæda the history of Northumbria became in fact little more than a wild story of lawlessness and bloodshed. King after king was swept away by treason and revolt, the country fell into the hands of its turbulent nobles, its very fields lay waste, and the land was scourged by famine and plague. An anarchy almost as complete fell on Wessex after the recovery of its freedom. Only in Mid-England was there any sign of order and settled rule. The crushing defeat at Burford, though it had brought about revolts which stripped Mercia of all the conquests it had made, was far from having broken the Mercian power. Under the long reign of Offa, which went on from 758 to 796, it rose again to all but its old dominion. Since the dissolution of the temporary alliance which Penda formed with the Welsh King Cadwallon the war with the Britons in the west had been the one great hindrance to the progress of Mercia. But under Offa Mercia braced herself to the completion of her British conquests. Pushing after 779 over the Severn, and carrying his ravages into the heart of Wales, Offa drove the King of Powys from his capital, which changed its old name of Pengwern for the significant English title of the Town in the Scrub or Bush, Scrobbesbyryg, Shrewsbury. Experience however had taught the Mercians the worthlessness of raids like these and Offa resolved to create a military border by planting a settlement of Englishmen between the Severn, which had till then served as the western boundary of the English race, and the huge "Offa's Dyke" which he drew from the mouth of Wye to that of Dee. Here, as in the later conquests of the West-Saxons, the old plan of extermination was definitely abandoned and the Welsh who chose to remain dwelled undisturbed among their English conquerors. From these conquests over the Britons Offa turned to build up again the realm which had been shattered at Burford. But his progress was slow. A reconquest of Kent in 775 woke anew the jealousy of the West-Saxons; and though Offa defeated their army at Bensington in 779 the victory was followed by several years of inaction. It was not till Wessex was again weakened by fresh anarchy that he was able in 794 to seize East-Anglia and restore his realm to its old bounds under Wulfhere. Further he could not go. A Kentish revolt occupied him till his death in 796, and his successor Cenwulf did little but preserve the realm he bequeathed him. At the close of the eighth century the drift of the English peoples towards a national unity was in fact utterly arrested. The work of Northumbria had been foiled by the resistance of Mercia; the effort of Mercia had broken down before the resistance of Wessex. A threefold division seemed to have stamped itself upon the land; and so complete was the balance of power between the three realms which parted it that no subjection of one to the other seemed likely to fuse the English tribes into an English people.
The Northmen
The union which each English kingdom in turn had failed to bring about was brought about by the pressure of the Northmen. The dwellers in the isles of the Baltic or on either side of the Scandinavian peninsula had lain hidden till now from Western Christendom, waging their battle for existence with a stern climate, a barren soil, and stormy seas. It was this hard fight for life that left its stamp on the temper of Dane, Swede, or Norwegian alike, that gave them their defiant energy, their ruthless daring, their passion for freedom and hatred of settled rule. Forays and plunder raids over sea eked out their scanty livelihood, and at the close of the eighth century these raids found a wider sphere than the waters of the northern seas. Tidings of the wealth garnered in the abbeys and towns of the new Christendom which had risen from the wreck of Rome drew the pirates slowly southwards to the coasts of Northern Gaul; and just before Offa's death their boats touched the shores of Britain. To men of that day it must have seemed as though the world had gone back three hundred years. The same northern fiords poured forth their pirate-fleets as in the days of Hengest or Cerdic. There was the same wild panic as the black boats of the invaders struck inland along the river-reaches or moored round the river isles, the same sights of horror, firing of homesteads, slaughter of men, women driven off to slavery or shame, children tossed on pikes or sold in the market-place, as when the English themselves had attacked Britain. Christian priests were again slain at the altar by worshippers of Woden; letters, arts, religion, government disappeared before these northmen as before the northmen of three centuries before.
Ecgberht
In 794 a pirate band plundered the monasteries of Wearmouth and Jarrow, and the presence of the freebooters soon told on the political balance of the English realms. A great revolution was going on in the south, where Mercia was torn by civil wars which followed on Cenwulf's death, while the civil strife of the West-Saxons was hushed by a new king, Ecgberht. In Offa's days Ecgberht had failed in his claim of the crown of Wessex and had been driven to fly for refuge to the court of the Franks. He remained there through the memorable year during which Charles the Great restored the Empire of the West, and returned in 802 to be quietly welcomed as King by the West-Saxon people. A march into the heart of Cornwall and the conquest of this last fragment of the British kingdom in the south-west freed his hands for a strife with Mercia, which broke out in 825 when the Mercian King Beornwulf marched into the heart of Wiltshire. A victory of Ecgberht at Ellandun gave all England south of Thames to the West-Saxons, and the defeat of Beornwulf spurred the men of East-Anglia to rise in a desperate revolt against Mercia. Two great overthrows at their hands had already spent its strength when Ecgberht crossed the Thames in 828, and the realm of Penda and Offa bowed without a struggle to its conqueror. But Ecgberht had wider aims than those of supremacy over Mercia alone. The dream of a union of all England drew him to the north. Northumbria was still strong; in learning and arts it stood at the head of the English race; and under a king like Eadberht it would have withstood Ecgberht as resolutely as it had withstood Æthelbald. But the ruin of Jarrow and Wearmouth had cast on it a spell of terror. Torn by civil strife, and desperate of finding in itself the union needed to meet the northmen, Northumbria sought union and deliverance in subjection to a foreign master. Its thegns met Ecgberht in Derbyshire, and owned the supremacy of Wessex.
