Geoffrey of Monmouth's Historia Regum Britanniae (History of the Kings of Britain) is a seminal work that has profoundly shaped the understanding and mythos of early British history. Written in Latin around 1136, this text presented a comprehensive, albeit legendary, chronicle of British monarchs, from the Trojan exile Brute to the death of Cadwallader in the 7th century. It filled a perceived void in historical records, particularly regarding figures like King Arthur, whose deeds were widely celebrated orally but lacked detailed written accounts.

Unveiling Legendary British History: Geoffrey's Monumental Work

Geoffrey of Monmouth, an esteemed chronicler and educator, felt a profound lack of historical documentation for the kings of Britain before the Incarnation of Christ and even for later figures like King Arthur, despite their enduring fame in oral traditions. He sought to rectify this gap, a quest that led to the creation of his Histories of the Kings of Britain.

His primary source, as he claimed in the dedicatory epistle, was an ancient book in the "British language" provided by Walter, Archdeacon of Oxford. This mysterious text reportedly detailed the succession of kings from Brute, the first King of the Britons, to Cadwallader. Geoffrey undertook the laborious task of translating this volume into Latin, intentionally using a "rustic manner of speech" to ensure clarity and avoid burdening readers with overly ornate language.

The work was dedicated to Robert, Earl of Gloucester, a man praised for his learning and military prowess, described as the son of Henry, King of the English, and seen as a "second Henry" by Britain. Geoffrey humbly asked Robert to lend his "deep sea of knowledge" to correct and refine the text, implying that the work's ultimate merit should reflect Robert's guidance rather than Geoffrey's own modest abilities.

Britain: An Island of Wonders and Peoples

Geoffrey begins his chronicle with a vivid description of Britain, portraying it as an island of immense natural wealth and strategic importance.

Location: Situated in the Western Ocean, between Gaul and Ireland.
Dimensions: Approximately 800 miles in length and 200 miles in breadth.
Natural Bounty: Abundant in metals, fertile fields for diverse crops, forests teeming with wild deer, lush meadows, clear well-springs, and rivers rich with fish.
Key Rivers: Thames, Severn, and Humber, acting as "three arms" facilitating overseas trade and traffic.
Cities: In ancient times, Britain was graced by "twice ten cities, moreover, and twice four" (28 cities). Some were then ruined, while others stood whole with "churches of the saints with towers builded wondrous fair on high."
Inhabitants: Comprised five peoples: Romans, Britons, Saxons, Picts, and Scots. The Britons were the original settlers, but their pride led to divine vengeance, causing them to yield to the Picts and Saxons.

The Trojan Origin: Brute's Journey to Britain

Geoffrey's narrative firmly establishes a Trojan lineage for the Britons, tracing their origins back to the aftermath of the Trojan War.

Aeneas's Legacy: After the fall of Troy, Aeneas fled to Italy, married Lavinia, and founded the kingdom of Italy. His son, Ascanius, later founded Alba on Tiber.
The Birth of Brute: Ascanius's son, Silvius, secretly married Lavinia's niece. Wizards prophesied their child would be a boy who would slay both parents and, after much travel, achieve high honors as an exile. The prophecy came true: the mother died in childbirth, and the boy was named Brute. At 15, Brute accidentally killed his father, Silvius, with an arrow during a hunt, leading to his exile from Italy.

Brute's Exile and the Trojan Uprising in Greece

Brute fled to Greece, where he encountered the descendants of Helenus (son of Priam), who were enslaved under King Pandrasus. These Trojans had been brought to Greece by Pyrrhus, son of Achilles, after the overthrow of Troy. Brute, recognizing their shared lineage, joined them and quickly gained renown for his "knighthood and prowess." His fame attracted more Trojans, who, having multiplied to 7,000 without counting women and children, implored him to be their king and liberate them from Greek bondage.

Assaracus, a high-ranking Greek youth of Trojan descent, also sought Brute's aid against his brother's claims to three castles. Brute, seeing the numerical strength and the strategic advantage of Assaracus's strongholds, agreed to lead the Trojans.

The Confrontation with Pandrasus

Brute, now Duke of the Trojans, sent a letter to King Pandrasus, asserting the Trojans' right to liberty and offering to either inhabit the forests they had occupied or depart peacefully. Pandrasus, enraged by their audacity, levied an army to hunt them down. Brute, however, launched a surprise attack with 3,000 men on Pandrasus's unsuspecting forces near the stronghold of Sparatinum, inflicting a "grievous slaughter" and defeating the Greeks.

Capture of Antigonus and Anacletus: During the battle, Pandrasus's brother, Antigonus, attempted to rally the Greeks but was captured along with his comrade Anacletus.
Siege of the Stronghold: Pandrasus regrouped and besieged the stronghold where Brute had garrisoned his men, believing Brute and his prisoners were inside. He employed battering rams and diverted rivers to hasten their surrender.

Brute's Cunning Stratagem

Fearing that his besieged men, suffering from scarcity, might be forced to surrender, Brute devised a daring night attack. He coerced Anacletus, under threat of death, to feign an escape with Antigonus and lead the Greek sentinels into a forest ambush. Anacletus successfully lured the guards, who were then slaughtered by Brute's concealed forces. Brute's men then infiltrated the Greek camp, awaiting his signal (a horn blow after securing the King's pavilion). The subsequent onslaught resulted in a "most terrible slaughter" of the sleeping Greeks.

The Treaty and Brute's Marriage

With Pandrasus captured, the Trojans debated their demands. Mempricius, a wise elder, advised against settling in Greece, foreseeing eternal hatred from the Greeks. Instead, he proposed:

Ignoge: Pandrasus's eldest daughter, as a wife for Brute.
Resources: Gold, silver, ships, and provisions for a voyage to other lands.

Pandrasus, recognizing the gods were against him and valuing his life above all, agreed to these terms. He provided 324 ships, laden with supplies, and married his daughter Ignoge to Brute. The Trojans, now free, set sail from Greece.

The Prophecy of Diana and the Voyage to Britain

After two days, the Trojans landed on the deserted island of Leogecia. Brute sent men inland, who discovered a deserted city with a temple of Diana. Brute, along with Gerion the augur and twelve elders, performed a sacrifice to Diana, Jove, and Mercury, seeking divine guidance for a permanent home. Brute addressed Diana: "Goddess and forest Queen... Tell me what lands thy will it is we dwell in? What sure abode?"

Diana's response came in a vision to Brute:

"Brute, - past the realms of Gaul, beneath the sunset Lieth an Island, girt about by ocean, Guarded by ocean - erst the haunt of giants, Desert of late, and meet for this thy people. Seek it! For there is thine abode for ever. There by thy sons again shall Troy be builded; There of thy blood shall Kings be born, hereafter Sovran in every land the wide world over."

Filled with joy and conviction, Brute's company resumed their westward voyage. Their journey took them past the Altars of the Phileni, the Salt-pans, and through the Tyrrhene Sea, where they encountered and defeated pirates. They then reached Mauritania, where a lack of supplies forced them to pillage the region before sailing to the Columns of Hercules, encountering Sirens along the way.

Corineus and the Aquitaine Campaign

In the Tyrrhene Sea, Brute's fleet met four generations of Trojans, exiles from Antenor's flight, led by the formidable Duke Corineus. Known for his "mighty in body, valiance and hardiness," Corineus was a giant-wrestler. He and his people, later called Cornishmen, joined Brute.

They landed in Aquitaine, then ruled by King Goffarius Pictus. Corineus, hunting deer in the king's forest without leave, killed an envoy named Imbert. This provoked Goffarius to assemble a large army. Brute and Corineus met the enemy, engaging in a fierce battle. Corineus, demonstrating incredible valor, broke through the enemy ranks, slaying hundreds with his battle-axe and rallying his men. The Gauls, believing the Cornishmen were more numerous, fled. Brute, though victorious, was concerned by his dwindling numbers and the Gauls' constant replenishment. He decided to continue his quest for the prophesied island.

Brute's Landing in Albion and the Founding of Britain

Brute returned to his fleet, loaded with spoils, and sailed to the promised island, landing safely at Totnes. The island, then named Albion, was inhabited only by a few giants. Attracted by the "pleasant aspect of the land" and its abundance of fish and deer, Brute and his companions resolved to settle there. They drove the giants into mountain caverns and divided the land.

Naming Britain: Brute renamed the island Britain and his companions Britons, after himself, to perpetuate his memory. The language, formerly Trojan or "crooked Greek," became British.
Corineus and Cornwall: Corineus received the westernmost part of the island, which he named Cornwall (from cornu, meaning 'horn' of Britain, or a corruption of his name) and its people Cornishmen. He particularly enjoyed wrestling with the local giants.
Goemagot's Leap: A notable giant, Goemagot (12 cubits tall), attacked Brute's festival. Brute's men slew all the giants but Goemagot, whom Brute reserved for a wrestling match with Corineus. Corineus, despite having three ribs broken, lifted Goemagot and hurled him from a high cliff into the sea, where he was mangled on the rocks below. This spot became known as "Lamgoemagot," or "Goemagot's Leap."

Founding New Troy (London)

Brute sought a suitable site for a chief city and found it by the River Thames. He founded New Troy (Trinovantum), which was later corrupted to London. King Lud, brother of Cassibelaunus, later fortified it and renamed it Kaerlud (City of Lud), sparking a contention with his brother Nennius over the name, as mentioned by Gildas. Brute granted laws to the citizens and buried in Trinovantum near the Temple of Concord.

The Succession of Kings: Brute to Lear

Geoffrey's chronicle details a long line of kings, starting with Brute's sons:

Locrine, Albanact, and Camber: Brute's three sons divided Britain after his death. Locrine, the eldest, received Loegria (middle Britain), Camber received Cambria (Wales), and Albanact, the youngest, received Albany (Scotland). Albanact was later killed by Humber, King of the Huns, who was subsequently drowned by Locrine in the river now bearing his name.
Locrine's Treachery: Locrine fell in love with Estrildis, a German princess captured from Humber, despite being pledged to Corineus's daughter, Gwendolen. He married Gwendolen but secretly kept Estrildis for seven years in an underground chamber in Trinovant, fathering a daughter, Sabrina. Gwendolen bore him a son, Maddan.
Gwendolen's Revenge: After Corineus died, Locrine abandoned Gwendolen and made Estrildis his queen. Gwendolen raised an army from Cornwall, fought Locrine at the River Stour, and killed him. She then drowned Estrildis and Sabrina in the river, which she named Sabrina (Severn) after her stepdaughter. Gwendolen ruled for 15 years before ceding the throne to her son Maddan.
Maddan and Mempricius: Maddan ruled peacefully for 40 years. His sons, Mempricius and Malim, fought over the kingdom. Mempricius treacherously slew Malim, becoming a tyrant. He later abandoned his wife and son Ebraucus for a life of "unclean living" and was devoured by wolves while hunting.
Ebraucus: Reigned for 40 years, conducted expeditions into Gaul, founding Kaerebrauc (York) and Alclud, and Mount Agned (Castle of Damsels). He had 20 sons and 30 daughters, whom he sent to Italy to marry Trojans or to Germany to conquer new lands.
Brute Greenshield, Leil, Hudibras: Brute Greenshield succeeded Ebraucus, followed by Leil (founder of Kaerleil/Carlisle) and Hudibras (founder of Kaerlem/Canterbury, Kaerguen/Winchester, and Mount Paladur/Shaftesbury, where an eagle supposedly prophesied).

The Tragic Tale of King Lear

Bladud's Demise: Hudibras was succeeded by his son Bladud, who built Kaerbadon (Bath) with its perpetual hot springs dedicated to Minerva. A skilled necromancer, Bladud tragically died attempting flight with self-made wings, falling onto Apollo's temple in Trinovantum.
King Lear and His Daughters: Bladud's son, Lear, ruled for 60 years, founding Kaerleir (Leicester). Having no male heir, he decided to divide his kingdom among his three beloved daughters: Goneril, Regan, and Cordelia. To determine the largest share, he asked each how much she loved him.
Goneril: Declared she loved him "dearer... than the very soul that dwelt within her body." Lear promised her a third of Britain and a husband of her choice.
Regan: Claimed she loved him "better than all the world beside." Lear promised her the same dignity and another third of the kingdom.
Cordelia: Observing her sisters' flattery, she chose a different approach, saying, "Father mine, is there a daughter anywhere that presumeth to love her father more than a father?...So much as thou hast, so much art thou worth, and so much do I love thee." Lear, indignant, disinherited her, promising only a marriage to a foreigner without land or fee.
Cordelia's Marriage: King Aganippus of the Franks, hearing of Cordelia's beauty, married her without dowry, stating he had enough wealth and sought only sons from her to inherit his lands. Cordelia was sent to Gaul.
Lear's Decline and Exile: As Lear aged, his sons-in-law (Dukes of Cornwall and Albany, Goneril's and Regan's husbands) rebelled and stripped him of his power. Goneril limited his retinue from 60 to 30 knights, then Regan reduced it to 5. When he returned to Goneril, she would only allow him one knight. Distraught and reflecting on his "lost happiness," Lear decided to seek help from Cordelia in Gaul. He traveled across the Channel, weeping over his diminished status.
Cordelia's Compassion and Lear's Restoration: Cordelia, upon hearing of her father's plight, sent him gold and silver, instructing him to go to another city, be bathed, clothed, and given a retinue of 40 knights. Only then was his arrival to be announced to Aganippus and herself. Lear was honorably received and given control over Gaul. Aganippus gathered an army from Gaul, and Lear, with Aganippus and Cordelia, returned to Britain, defeated his sons-in-law, and regained his kingdom. Lear died three years later and was buried by Cordelia in a chamber under the River Soar at Leicester, dedicated to Janus.

Cordelia, Margan, and Cunedag

Cordelia's Reign: Cordelia ruled Britain peacefully for five years. However, her nephews, Margan (son of Maglaunus, Duke of Albany) and Cunedag (son of Henvin, Duke of Cornwall), both powerful youths, resented being ruled by a woman. They rebelled, defeated Cordelia in battles, and imprisoned her. Overwhelmed by grief, Cordelia took her own life.
Division and Conflict: Margan and Cunedag divided the island, with Margan taking the north (Humber to Caithness) and Cunedag the west (other side of the Humber). Two years later, Margan, incited by discontented nobles, marched against Cunedag, claiming the entire island as the elder. Cunedag defeated and pursued Margan, eventually slaying him in a Welsh village, which was renamed Margan. Cunedag then became sole ruler, reigning gloriously for 33 years.

Subsequent Rulers and the Molmutine Laws

Ferrex and Porrex: After Cunedag, a line of kings followed, including Rivallo, Gurgustius, Sisillius, Lago, Kinmarch, and Gorbodug. Gorbodug's sons, Ferrex and Porrex, disputed the succession. Porrex attempted to kill Ferrex, who fled to Gaul for help from King Suard of the Franks. Ferrex returned, but was slain by Porrex. Their mother, Widen, avenged Ferrex by hacking Porrex to pieces in his sleep. This led to a long period of civil war and rule by five warring kings.
Dunwallo Molmutius: Eventually, Dunwallo Molmutius, son of King Cloten of Cornwall, emerged. Renowned for his prowess, he defeated and slew Ymner, King of Loegria. He then faced a coalition of Rudauc (King of Cambria) and Stater (King of Albany). In battle, Dunwallo strategically donned the armor of slain enemies, infiltrated the enemy ranks with 600 men, and killed Rudauc and Stater. He then united the island, crowned himself king, and established the Molmutine Laws, which were celebrated even by the English. These laws decreed inviolability for temples, cities (providing sanctuary for runaways and the guilty), and even the "ploughs of the husbandmen." Under his rule, violence and robbery ceased. Dunwallo ruled for 40 years and was buried in Trinovantum.

Belinus and Brennius: Fraternal Strife and Roman Intervention

Succession Dispute: After Dunwallo's death, his sons, Belinus and Brennius, fought over the kingdom. Their friends intervened, agreeing that Belinus, as the elder, would have the crown of the island, Loegria, Cambria, and Cornwall, while Brennius would be subject to him, ruling Northumbria. They ruled peacefully for five years.
Brennius's Rebellion: False advisors corrupted Brennius, urging him to marry the King of Norway's daughter and reclaim his lost dignity. Brennius sailed to Norway, married the princess, and returned with a Norwegian force. Belinus, angered by his brother's actions, marched to meet him.
Naval Battle and Danish King: Before reaching Britain, Brennius was attacked at sea by Guichtlac, King of the Danes, who was enamored with Brennius's bride. A storm scattered their ships, driving Guichtlac and the princess to the coast of Northumbria, where they were captured by Belinus. Belinus, seizing the opportunity, imprisoned Guichtlac but released him in exchange for Denmark's submission and annual tribute.
Battle of Calaterium: Belinus and Brennius met in battle in the forest of Calaterium. The Britons prevailed, inflicting 15,000 casualties on the Norwegians. Brennius escaped to Gaul.

Roman Period and the Fall of Britain

Octavius and Maximian: The narrative later introduces King Octavius, an aging British king who, having no male heir, sought a successor and husband for his daughter. His barons proposed Maximian, a powerful Roman figure, as a suitable candidate. Maurice, son of the Duke of Cornwall, was sent to Rome to invite Maximian to Britain, offering him the crown and Octavius's daughter. Maximian, who was feuding with Emperors Gratian and Valentinian, saw this as an opportunity to gain strength and eventually seize the Roman Empire. He sacked Frankish cities for wealth and sailed to Hamo's Port with a large army.
Conan Meriadoc's Resistance: Conan, Octavius's nephew, was sent to repel Maximian, viewing his arrival as an invasion. Maurice, however, tricked Conan into believing Maximian was an envoy seeking peace, allowing Maximian to establish a foothold.
Maximian's Reign and Departure: Maximian eventually became king and, according to Geoffrey, took many of Britain's fighting men to Gaul, leaving the island vulnerable. He was later slain in Rome.
Vulnerability and Roman Abandonment: The removal of British warriors by Maximian left Britain defenseless against renewed incursions from Scots, Norwegians, and Danes. The Britons appealed to Rome for aid, receiving a legion that temporarily drove back their enemies. The Romans then advised the Britons to build a turf wall between Albany and Deira for protection and to fight their own battles, as Rome could no longer commit resources. The Romans eventually departed, leaving Britain to its fate.

The Arrival of the Saxons

Gratian Municeps: After Maximian's death, Gratian Municeps, a Roman, seized the British crown but was slain by the populace for his tyranny. This opened the door for more barbarian invasions.
Vortigern and Hengist: Vortigern, a British king, faced relentless barbarian attacks. He unwisely invited two Saxon chieftains, Hengist and Horsus, to help defend Britain. Hengist's daughter, Rowena, captivated Vortigern, who, despite being a Christian, married her, granting Hengist the province of Kent in return. This marriage and the granting of land to heathens deeply angered British barons and Vortigern's own sons (Vortimer, Katigern, Pascentius). Vortigern was also criticized for the spread of the Pelagian heresy, which St. Germanus and Lupus came to combat.
Saxon Expansion: Hengist, now Vortigern's father-in-law and counselor, advised him to invite more Saxons, including his son Octa and nephew Ebissa. This marked the beginning of significant Saxon settlement, eventually leading to their dominance.

Key Figures and Their Significance

Brute: The legendary founder of Britain, establishing a Trojan lineage for the Britons. His journey and struggles lay the foundation for the entire historical narrative.
Corineus: A mighty warrior, Brute's loyal companion, and the namesake of Cornwall. His strength and ferocity are emphasized through feats like wrestling Goemagot.
King Lear: A tragic figure whose story highlights themes of filial ingratitude and the consequences of unwise decisions, ultimately finding redemption through Cordelia's loyalty.
Cordelia: Lear's loyal and compassionate daughter, representing true affection over flattery. Her story is a poignant counterpoint to her greedy sisters.
Dunwallo Molmutius: A powerful and just king who unified Britain after civil strife and established the foundational "Molmutine Laws," known for ensuring peace and sanctuary.
Belinus and Brennius: Brother kings whose initial conflict and eventual reconciliation (or continued struggle) reflect the internal divisions within early Britain.
Maximian: A Roman figure invited to rule Britain, whose actions (taking British warriors to the continent) inadvertently weaken the island, leading to its vulnerability.
Vortigern: The British king who, in a desperate move, invited the Saxons, ultimately paving the way for their conquest of Britain. His marriage to Rowena symbolizes the intertwining, and eventual subjugation, of British and Saxon fates.
Hengist: The cunning Saxon chieftain who strategically exploits Vortigern's weakness to establish a Saxon presence in Britain, setting the stage for future conflicts.

The Lasting Legacy of Geoffrey of Monmouth's Histories

Geoffrey of Monmouth's Histories had an immense impact, becoming a primary source for writers for centuries, even though later historians questioned its factual accuracy. It provided a grand, epic narrative for Britain, connecting its origins to the prestigious Trojan lineage and offering a continuous line of kings. It popularized the legends of King Lear and, most significantly, cemented the figure of King Arthur in the Western imagination, providing many details that would become central to Arthurian romance.

Critical Context: Legendary vs. Historical Accuracy

While Geoffrey presented his work as a historical account, modern scholarship classifies it as pseudo-history or legend. His primary "ancient British book" has never been found, and many of his characters and events lack corroboration from other contemporary sources. Nevertheless, its cultural impact was profound. It gave medieval Britons a sense of glorious national past, influencing literature, folklore, and even political claims for centuries.
