Empress Matilda and the Anarchy: A Comprehensive Briefing

Empress Matilda’s defiance during "The Anarchy" redefined medieval power. As the first woman to claim the English throne, she survived harrowing sieges and political betrayal to secure the Plantagenet dynasty. Though never crowned Queen, her tenacity as a military leader and advisor ensured her son, Henry II, inherited a kingdom.

At a Glance: Empress Matilda & The Anarchy

The era of Empress Matilda was a turbulent period of civil unrest that fundamentally reshaped the English monarchy. Here is the essential breakdown of the conflict and its key player.

Who: Empress Matilda, daughter of Henry I, and her cousin Stephen of Blois.
What: The Anarchy, a nineteen-year civil war (1135–1154) fought over the succession of the English throne.
Why: Despite barons swearing an oath to Matilda, Stephen seized the crown upon Henry I's death, claiming a woman could not rule and that the late King had changed his mind.
Outcome: A military stalemate resolved by the Treaty of Wallingford, which allowed Stephen to keep the throne but named Matilda’s son, Henry II, as his legal heir.
The "First": Matilda was the first woman to be designated heir to the English throne and the first to rule (as "Lady of the English") in her own right, even without a formal coronation.

Written by Simon Williams

The career of Empress Matilda (1102–1167) represents a seminal moment in English history, marking the first time a woman sought to claim the throne of England in her own right. Following the death of her father, King Henry I, in 1135, England descended into a nineteen-year civil war known as 'The Anarchy' after Matilda’s cousin, Stephen of Blois, seized the crown.

Matilda’s life was defined by extreme adaptability and the exercise of power across three distinct phases: her tenure as Empress of the Holy Roman Empire, her military and political campaign for the English throne, and her final years as a powerful advisor to her son, King Henry II. Despite failing to secure an official coronation, Matilda’s tenacity ultimately preserved her father’s lineage and established the Plantagenet dynasty. Her legacy has shifted from medieval critiques of her 'unfeminine' boldness to modern recognition of her as a formidable political architect.

I. Foundations of Power: Early Life and the Imperial Education

Matilda’s early life provided the requisite education and status to function as a significant political force.

A. The Imperial Marriage

Marriage to Henry V: Born in 1102 to Henry I and Edith Matilda of Scotland, Matilda was betrothed at age seven to the Holy Roman Emperor, Henry V.
Imperial Education: Sent to Germany in 1110, she was educated under Archbishop Bruno of Trier. She became fluent in Latin and Middle High German and was trained in grammar and imperial politics.
Wielding Authority: By age 16, Matilda acted as regent for her husband over his Italian holdings. She also served as a recognised intercessor, negotiating on behalf of figures such as Godfrey, Count of Leuven.

B. The Succession Crisis

The White Ship Disaster: In 1120, Matilda’s brother and the sole legitimate male heir, William Adelin, died in a shipwreck.
Oaths of Allegiance: Henry I forced his barons in 1127 to swear an oath accepting Matilda as his heir if he died without male issue.
Second Marriage: Following the death of the Emperor in 1125, Matilda was married to Geoffrey Plantagenet, Count of Anjou, in 1128. This marriage was intended to secure alliances and produce male heirs, resulting in the birth of the future Henry II in 1133.

II. The Anarchy: The Struggle for the English Throne (1135–1154)

The civil war between Matilda and Stephen was characterised by shifting loyalties, sieges, and the strategic use of fortified bases.

A. The Outbreak of War

When Henry I died in 1135, Stephen of Blois executed a coup, supported by the people of London and the Archbishop of Canterbury. Matilda launched a military invasion in 1139, supported by several key figures:

Robert, Earl of Gloucester: Matilda’s half-brother and her primary military commander.
King David I of Scotland: Her uncle, who invaded Northern England.
Strategic Bases: Matilda operated out of Arundel Castle in Sussex and Oxford Castle.

B. The Peak and Pivot (1141)

The Battle of Lincoln: In February 1141, Matilda’s forces defeated Stephen, capturing him and imprisoning him at Bristol Castle.
Lady of the English: Matilda assumed the title Domina Anglorum (Lady of the English) and prepared for her coronation in London.
The London Failure: Matilda’s refusal to grant traditional tax concessions and favours enraged the Londoners. An armed mob forced her to flee the city just prior to her coronation.
Prisoner Exchange: Following the capture of her supporter, Robert of Gloucester, by the forces of Stephen’s wife (also named Matilda), a prisoner exchange was forced. Stephen was released in exchange for Robert, prolonging the conflict.

C. The Escape from Oxford (1142)

While besieged at Oxford Castle in the winter of 1142, Matilda famously escaped capture by being lowered from St George’s Tower by ropes. Dressed in white to camouflage herself against the snow, she crossed the frozen River Isis and walked six miles to safety in Abingdon.

III. Political Instruments and Governance Strategies

Matilda did not rely solely on military force; she utilised established medieval methods of female power to gain and maintain influence.

A. Charters and Donations

Matilda used the issuance and confirmation of charters to solidify alliances.

Confirmation of Stephen’s Gifts: In acts such as the 'Act for Andwell', she confirmed gifts previously made by King Stephen. This reassured religious houses that their lands would remain secure under her rule, regardless of the war’s outcome.
Religious Patronage: She made significant donations to monasteries and churches (e.g., Godstow), which served both spiritual purposes and as displays of sovereign authority.

B. Peaceful Brokering

Despite chroniclers' claims of her arrogance, Matilda demonstrated a capacity for diplomacy, notably during the negotiations for the prisoner exchange in 1141 and later as a mediator between her son and various church and political figures.

IV. Resolution and Later Governance

Matilda eventually withdrew from the direct conflict in England in 1147 following the death of Robert of Gloucester, shifting her focus to her son’s succession.

A. The Treaty of Westminster (1153)

A compromise was reached in 1153 after Henry Plantagenet invaded England. The Treaty (also known as the Treaty of Wallingford) established that Stephen would remain king until his death, after which he would be succeeded by Henry.

B. Advisor to the King

When Henry II ascended the throne in 1154, Matilda remained an influential figure:

Governance of Normandy: She governed the Duchy of Normandy on behalf of her son.
Thomas Becket Dispute: Matilda was a vocal advisor on church-state relations. She famously opposed the appointment of Thomas Becket as Archbishop of Canterbury, predicting he would cause strife between the crown and the church.
International Intercessor: Figures such as Pope Anastasius IV and King Louis VII of France wrote directly to Matilda, recognising her influence over Henry II and seeking her aid in diplomatic matters.

V. Historiographical Perspectives

The perception of Matilda has evolved significantly across centuries of historical scholarship.

Era	Source/Historian	Perspective on Matilda
Medieval	Gesta Stephani	Criticised her for 'unfeminine' arrogance and boldness; contrasted her negatively with Stephen's wife.
Medieval	William of Malmesbury	Generally more favourable, portraying her as the rightful heir to Henry I.
Victorian	William Stubbs	Described her as possessing the 'pride and tyrannical intolerance' of her father without his self-control.
20th Century	Marjorie Chibnall	Shifted focus to her agency, religious patronage, and governance in Normandy.
21st Century	Catherine Hanley	Redefined her as a trailblazer and a political architect who adapted to shifting circumstances.

VI. Legacy and Summary of Accomplishments

Empress Matilda’s career is encapsulated by her epitaph: 'Great by birth, greater by marriage, greatest in her offspring.' However, the historical record suggests her own actions were the true driver of her legacy:

First Female Heir: She was the first woman named as successor to the English throne.
Dynastic Architect: Her dogged determination during the Anarchy ensured the throne passed to the Plantagenet line, which ruled England for 331 years.
Political Survivor: She successfully navigated the politics of two major medieval powers—the Holy Roman Empire and England—and transitioned into a respected elder statesman and advisor.
Cultural Symbol: Her miraculous escapes and military tenacity broke the contemporary mould of the 'passive' medieval noblewoman.

Frequently Asked Questions

Why is Empress Matilda called 'Empress' if she was never crowned Queen of England?

The title 'Empress' refers to her first marriage to Henry V, the Holy Roman Emperor. She was crowned Empress in Rome and used the title for the rest of her life, as it held significantly higher prestige than 'Countess' or even 'Queen'. In England, she officially styled herself as Domina Anglorum (Lady of the English) while campaigning for the throne.

Did Empress Matilda ever actually rule England?

Briefly, yes, but not formally as Queen. In 1141, after capturing King Stephen at the Battle of Lincoln, she controlled much of the country and moved to London for her coronation. However, her unpopularity with the Londoners—driven by her refusal to lower taxes—caused a riot that forced her to flee the city just days before the ceremony.

How did Empress Matilda escape the Siege of Oxford?

This is one of the most famous tales of the Middle Ages. In the winter of 1142, Matilda was trapped in Oxford Castle by Stephen’s forces. Under the cover of night, she and three knights wrapped themselves in white cloaks to blend into the heavy snow. They lowered themselves down the castle walls with ropes, crossed the frozen River Thames on foot, and walked through enemy lines to safety.

What was 'The Anarchy' actually like for the people?

Contemporary chroniclers described it as a time when "Christ and his saints slept." Because central authority had collapsed, local barons built "adulterine" (unauthorised) castles and fought private wars. This led to widespread lawlessness, the burning of crops, and heavy taxation of the peasantry by both sides.

Why did Empress Matilda eventually give up her claim?

After her half-brother and chief military strategist, Robert of Gloucester, died in 1147, Matilda’s military position weakened. Realising she might never be crowned, she shifted her focus to her son’s claim. She retired to Normandy in 1148, where she spent the rest of her life acting as a brilliant political advisor and regent for Henry II.

Is Empress Matilda related to the current British Royal Family?

Yes. Every English and British monarch from Henry II onwards is a direct descendant of Matilda. By securing her son’s succession, she ensured the survival of the Norman-Plantagenet bloodline.
