Vortigern
Vortigern was a legendary 5th-century King of the Britons featured in the work of early British writers such as Gildas, Nennius, Bede, Geoffrey of Monmouth and others. There is a debate over whether Vortigern was a term for a High King chosen by a consensus to rule or whether it was the name of a person such as a warlord, lesser King, or political leader.
This work takes it as the name of a person of high status who, through his ruthless cunning and experience, took over the rule of the Britons during dangerous times. He is usually presented in a bad light as a man of immoral and selfish character who used duplicity and deception to rise to the top of the British establishment of his day. Vortigern is usually blamed for encouraging the arrival of the Saxon and Germanic invaders to Britain. At first, he employed them as mercenaries to support him and to fight against the Picts and Scots, but later, he found he could not control them. Some scholars say the ruling elite of the Britons may deserve at least an equal share of the blame through their weakness and disarray in facing their enemies. Moreover, as far as the realm’s defence was concerned, he did the best he could with the resources available to him, which had been seriously depleted by the actions of earlier rulers.
Yet, some early writers pose questions about his morality and behaviour. Indeed, acts of lust, intrigue, murder, duplicity, and betrayal are the hallmarks of his reign. This work presents a brief overview of Vortigern’s rule, looking at some of these alleged acts and incidents, some of which resonate through the ages and are the very stuff of legends.
Vortigern Takes the Crown
According to Geoffrey of Monmouth, Vortigern set up Constans, the eldest of the sons of King Constantine II, who had been assassinated, to rule the Britons because he knew he could control him and eventually replace him. After arranging for his murder, he usurped the crown to find that one day, a cleverer and more ruthless man would appear on the scene. That man was Hengist, the leader of the Saxons, Angles, and Jutes in Britain.
After the assassination of Constans by Pict mercenaries controlled by Vortigern, no one else was available of suitable status, experience, or age to take his place. The rightful heirs to the throne of the Briton were Aurelius Ambrosius and his younger brother Uther, who were the sons of King Constantine II and the younger brothers of Constans. Unfortunately, they were just children and deemed too young to take the throne. Vortigern was the most experienced political figure of the Britons at the time and very ambitious. Insidiously, he had wormed his way into becoming the chief advisor of Constans while all the time working secretly to promote personal ambitions and quietly gaining power, authority and the King’s trust.
With the murder of Constans that he carefully and covertly set up, he stepped forward and seized the crown for himself. Not all the British nobles were friends of Vortigern, and some of these, fearing for the safety of the two young heirs, sent them into exile to Armorica for their safekeeping. There, they grew up safely and were taught the arts of royalty and leadership while preparing to return one day and reclaim the crown of the Britons.
Having seized the throne, Vortigern would find ruling the kingdom far from easy. In the north, Picts and Scots made frequent raids into his realm, and he also feared another impending and growing threat.
As the years passed, he was aware of the exiled royal brothers’ maturing and coming of age. He received reports of the building of a vast fleet and the mustering of a great army, and his spies confirmed his fears that they were intent on taking back their rightful inheritance. Taking stock of the situation, he found he was desperately short of men at arms to defend the kingdom.
Hengist and Horsa
While Aurelius and Uther had been growing up in Armorica, the kingdom of the Britons had faced many threats from the neighbouring Picts and Scots, who frequently raided the borders and made encroachments further into his kingdom. To deal with these invasions, he employed Saxon and other Germanic mercenaries to fight for him, and to begin with, this worked well. The Saxons, led by two brothers named Hengist and Horsa, were fierce warriors who defeated the Picts and Scots whenever they encountered them.
Hengist asked Vortigern for permission to bring more of his countrymen from Germany to help fight Britain’s enemies. Vortigern was pleased with the success of the Saxons and readily agreed. Therefore, Hengist brought in more warriors from Germany. Next, Hengist asked for a small portion of land to build a stronghold for him and his people. He only asked for a site that a leather thong made from a bull’s hide could encircle. Again, Vortigern granted his request. Taking a bull’s hide, he made a thin thong of sufficient length from the whole to completely encircle a site of his choosing. On this site, he built his stronghold known as Kaercorrei to the Britons and Thancastre, or Thong Castle to the Saxons. Hengist was quietly pleased with what had been granted and asked Vortigern for permission to bring in even more Saxon warriors, which Vortigern granted.
The Arrival of Rowena
More ships from Germany arrived, and with them came someone whom Hengist had said nothing to Vortigern about. As well as men at arms, they brought the Saxon princess named Rowena, who was the daughter of Hengist. She was one of the most beautiful and desirable German princesses of the time, and her arrival would enthral and captivate Vortigern. She would become an important, though covert player, in Hengist’s creeping influence over the King of the Britons.
With the arrival of Rowena and the new contingent of German fighters, Hengist invited Vortigern to a lavish banquet at his newly constructed stronghold of Thong Castle. Vortigern was pleased to accept the invitation, and after being shown around the castle and welcoming the warriors into his service, he was given a banquet in his honour. The wine flowed freely, and towards the end of the evening, Rowena appeared from her bedchamber carrying a golden cup of wine. Curtseying to Vortigern, she said, “Lauerd king wacht heil!”
Vortigern was surprised, delighted, and captivated by the grace and beauty of the girl, and he became enamoured with her. Turning to his interpreter, he asked what she had said and what his response should be. His interpreter told him she had called him “Lord King” and offered to drink to his health. He must answer by saying, “Drinc heil!” Taking the cup from her, he kissed her and drained it.
According to Geoffrey, this was how the tradition of toasting became popular in Britain. A person drinks to the health of someone saying, “Wacht heil!” who answers, “Drinc heil!”
The arrival of Rowena was a critical moment in the destiny of the Britons. Aided by vast quantities of beer and wine and the charm and beauty of this young Saxon princess, Vortigern was well and truly captivated. It was said at that moment the devil entered him, and he wanted her for his wife. For Vortigern, as a Christian, marriage to a pagan would have been a severe taboo. The wily Hengist was aware of this and consulted with his brother Horsa and others of his wise men present. Unanimously, they advised that he marry Rowena to Vortigern and demand the British province of Kent because of her royal lineage. Vortigern agreed to this without consulting his wise men or nobles. Furthermore, he gave Kent to Hengist without the knowledge or consent of Gorangan, the British noble who had ruled there. Although it may be said that Rowena was given to Vortigern, it became apparent that she possessed him.
As Hengist had calculated, his marriage to a pagan princess and the giving away of Kent fuelled discontent in the British nobles, for he already had a wife, three sons named Vortimer, Catigern, and Pascentius, and a daughter. Nevertheless, Vortigern and Rowena were married that night. Although Vortigern was pleased with his new wife, his nobles and sons were shocked and angry at his behaviour and threatened rebellion. Ominously, over the sea in Armorica, a more significant threat was steadily manifesting as Aurelius and Uther continued preparing their invasion plans.
To make matters worse, despite his love for Rowena and marriage to her, Vortigern further alienated his sons and nobles and set the church against him by fathering a child with his daughter.
Vortimer
With the ever-increasing number of Saxons arriving, the Britons became uneasy and openly resented Vortigern’s favouritism towards them. Vortimer, the son of Vortigern, rebelled against his father, took the crown and led the Britons against the Saxons. His brother Catigurn duelled with Horsa in battle, killing each other. After being deposed, Vortigern had remained with Rowena and her father among the Saxons while Vortimer had fought against them. In a series of battles, Vortimer drove Hengist and the Saxons from mainland Britain to the Isle of Thanet, where he besieged them with his ships, regularly attacking them.
Hengist could not match Vortimer and, knowing he was defeated, sent Vortigern to his son to plead for peaceful passage out of Britain with him and his Saxons. While a conference was being held on this proposal, with the Britons distracted, the Saxons escaped in their ships, sailing back to their homeland while leaving their women and children behind.
Rowena’s Poison
Even though Hengist was gone, Rowena secretly kept in touch with her father in their homeland. She allegedly poisoned Vortimer, who fell ill and died, leaving a power vacuum, and once again, Vortigern claimed the crown. With Vortimer dead, Rowena persuaded her husband to send a message to her father, inviting him back in a private capacity, which would allow him to bring a small entourage with him.
Hearing that Vortimer was dead, Hengist saw his chance, raised an army of three hundred thousand warriors, and built a fleet of ships to transport his men to the shores of Britain. When the news of such a vast army reached Vortigern, the British nobles were furious at the betrayal of goodwill and resolved to fight.
After receiving information from Rowena about the British resolve, Hengist devised a different plan. He sent messengers to Vortigern saying that he had only brought such a large army for fear of being attacked by Vortimer, claiming he had not known of his death. He suggested that when he arrived, Vortigern should pick and choose those of his army who should stay and those to be sent home. If Vortigern agreed, he should propose a time and place to meet unarmed and make a peace treaty.
The Treachery of the Long Knives
Vortigern was pleased to accept this as he was reluctant to let Hengist leave, both for the sake of Rowena and because of his usefulness in battle. He set a date for the Kalends of May, which was drawing near, and the meeting place would be the monastery of Ambrius on the mount of that name. Hengist readily agreed but had formulated a secret plan. He ordered all his Saxon soldiers accompanying him to conceal a long knife in their clothing. They were to act friendly and peacefully towards the Britons, encouraging them to drink heavily. When he deemed the time was right, he would cry out “Nemet oure Saxas”, meaning “get your knives,” and they were to seize their knives and slay the Briton nearest to them who would not have understood their language. The only Briton to be spared was Vortigern, who Hengist wanted alive.
The plan worked, and four hundred and sixty of Britain’s barons and nobles were assassinated, according to Geoffrey of Monmouth, and Vortigern was taken hostage. This murderous event became known as the Night of the Long Knives or Treachery of the Long Knives. It became synonymous with Saxon treachery and looked upon by the Britons after that with great anger. Only one of the intended victims escaped that night. His name was Eldol, the Earl of Gloucester. He would help Aurelius defeat Vortigern, capture Hengist in battle, and execute him.
Hengist Takes Control
Meanwhile, Hengist now had Vortigern firmly in his power and, with him, the kingdom of the Britons. Nevertheless, he would not kill him until he had wrung from him everything he needed. He demanded Vortigern give him all his fortified cities and fortresses in return for his life. With no other choice, Vortigern agreed. He was set free to watch as Hengist and his Saxons took London and then York, Lincoln and Winchester leaving a trail of devastation in their wake. Not knowing what else to do, Vortigern took what few followers remained and went to Cambria, where he was to seek counsel from his wise men.
Dinas Emrys: Merlin and the Two Dragons
Vortigern finally realised Hengist had dangerously outmanoeuvred him and consulted with his wise men. They advised him to find a strategically defensible site to build a new fortress to keep him and his followers safe, as Hengist had been given command of all the fortified places. After searching what remained of his kingdom, he finally settled on a place now named Dinas Emrys. His builders set to work, making good progress on the first day. When evening came, they went home expecting to continue building on that progress the following day. But in the morning, when they returned, they found all the walls they had built the previous day in a heap on the ground.
Bemused, they rebuilt what had fallen and again broke off from work in the evening, thinking they had set things right. In the morning, when they arrived expecting to make further progress with their work, they discovered once more that it had become a heap of rubble on the ground. This pattern repeated daily, and the building work did not progress. The exasperated Vortigern asked his wise men for guidance. They advised that he must seek out someone not born from a man who must then be sacrificed and his blood sprinkled on the foundations. He sent out his servants to find such a person. After a long search, they returned with a boy named Merlin Emrys, who would one day become the prophet and counsellor of the Kings of Britain.
Vortigern told Merlin he would be sacrificed, but Merlin demanded Vortigern bring him his wise men for questioning first. Vortigern agreed, and after Merlin questioned Vortigern, it became clear that they had no idea why the walls kept falling. Merlin explained to Vortigern that beneath the hill was an underground pool with two stone vessels, each containing a sleeping dragon. One dragon was red, and the other was white. It was the pool of water making the foundations unstable.
Merlin instructed Vortigern to dig below the foundations, and a pool was revealed. He then instructed Vortigern to drain the pool. As he had predicted, two stone containers, each holding a sleeping dragon, were found. One held a red dragon, the other a white, much to the amazement of all. When the dragons awoke, they immediately set about fighting each other. After a long and vicious struggle, the red dragon drove away the white dragon.
The Prophecies of Merlin
Merlin tested the wise men by asking what this meant, but none had any idea. He then interpreted the scene for Vortigern, explaining that the red dragon represented the Britons and the white dragon the Saxons. After a hard struggle, the red dragon would drive out the white dragon but warned it would return centuries later to rule Britain. Then, he made a long series of prophecies that impressed and awed Vortigern, who asked him how he would die.
Merlin told him he saw two possible deaths for him. He told him that as he spoke, Aurelius Ambrosius and his brother Uther had set sail for Britain at the head of a vast fleet carrying an invasion force and were disembarking at Totnes. The remaining Britons would flock to their banner, and they would seek him out and burn him in his tower in revenge for the death of their brother Constans and because he brought the Saxons to the shores of Britain. After finishing with him, they would attack Hengist and drive the Saxons from Britain. The next day, in proof of Merlin’s words, messages arrived in the morning telling of the arrival of Aurelius Ambrosius and Uther and an invasion army that had landed at Totnes. This would be the first possibility.
Then Merlin told Vortigern the second possibility would be at the hands of the Saxons, who were now, thanks to him, at work laying waste to the country. However, Merlin emphasised that he did not know who would get to him first. He predicted that Hengist would be killed and Aurelius Ambrosius would be crowned King of the Britons. He would right the wrongs done by the Saxons and bring peace to the country.
Unfortunately, his days would be cut short by poison. After him, Uther would be King, but he, too, would die of poisoning. He then foretold of the arrival of a king, believed to be Arthur, who would bring peace, unify Britain, and build a great empire. Merlin then advised him to seek out another site for his stronghold quickly.
Aurelius Ambrosius
News of the arrival of the two brothers and rightful heirs had spread like wildfire across Britain. The few war leaders and nobles left after the Treachery of the Long Knives had been scattered and leaderless. Eldol, the Earl of Gloucester, who had survived the treachery of Hengist, joined up with the brothers, as did the remaining warlords and nobles who had not attended the terrible event. They brought together the clergy and crowned Aurelius Ambrosius, the elder of the two brothers, the King of the Britons.
Although there was a clamour from these lords and clergy for the King to battle the Saxons immediately, Aurelius refused. He told them Vortigern would be brought to justice for the murder of Constans and for bringing in the Saxons to Britain. With this vengeance in mind, he marched his army to Caer Guorthegirn or the city or fortress of Vortigern, now known as Little Doward, where Vortigern had sought refuge from the Saxons.
The Burning of Vortigern
There are conflicting accounts of the death of Vortigern, but according to Geoffrey of Monmouth, Aurelius and Uther, with Eldol in assistance, attacked Vortigern’s last stronghold but could not breach the walls after several attempts. Aurelius then ordered that his archers rain burning arrows upon the fortress, turning it into a fiery inferno, killing all inside, including Vortigern and Rowena.
So it was that a man who had become the King of the Britons through treachery and murder was undone by Hengist, the Saxon leader who proved more treacherous, ruthless and cunning than he. Additionally, and importantly, it was Aurelius Ambrosius, in revenge for Vortigern murdering his father and brother and for bringing the Saxons to Britain’s shores, that finally brought about his downfall.
With the legendary Vortigern dead, King Aurelius Ambrosius turned his attention to Hengist and the Saxons, writing a new chapter in the legends and folklore of the Britons of the island of Britain.
