    • England lost Calais in January 1558, its last territory in France, held for over 200 years

  • Mary's two false pregnancies (1554 and 1557) meant no Catholic heir was produced

  • Mary accepted Elizabeth as her successor shortly before her death

    • Much of what she had worked for was undone within a year

  • The Spanish marriage was the central political decision of Mary’s reign

    • Many of the major events of the reign (the rebellion, the war with France, the loss of Calais) stemmed from it

Why did Mary want to marry Philip?

  • The succession problem:

    • Mary was 37 at her accession

      • Without a Catholic heir, Protestant Elizabeth would succeed

  • The Habsburg connection:

    • Mary's mother was Catherine of Aragon

    • Mary was close to the Spanish royal family and had been considered a potential wife for Charles V himself

  • Personal feeling:

    • Mary appears to have developed genuine affection for Philip; he did not reciprocate

  • Religious logic:

    • A Spanish alliance would strengthen the Catholic cause in England and across Europe

Opposition to marriage

Domestic opposition in England

  • Opposition came from across the political spectrum, not just from Protestants

  • These concerns translated into widespread unease and unpopularity at home, particularly among the political nation

    • Philip was a staunch Catholic

      • Protestants feared he would strengthen Mary's religious policy

    • Philip was heir to Spain and its vast empire

      • Many feared England would become a tool of Spanish ambitions

    • Xenophobic concerns

      • There was growing fear that Spanish advisers would dominate government and that England would be drawn into Habsburg wars

    • Parliament sent a delegation to dissuade Mary from the match

      • She ignored it

    • Gardiner proposed Edward Courtenay, Earl of Devon, as an English alternative

      • Which would have avoided foreign influence and reassured the political nation

      • Mary refused, as the match offered no strong international alliance and was politically less advantageous

International reaction

  • France was alarmed that England and Spain might encircle them

    • This increased the likelihood of England being drawn into European conflict

The marriage treaty, January 1554

  • The treaty was carefully negotiated to limit Philip's power and protect English interests

Term of the treaty

What it meant

Philip received the title of King but had no executive power

  • He could not make decisions about English government independently

  • The title was ceremonial only

Foreigners were forbidden from holding English government offices

  • Protected the English nation from Spanish officers taking control

Philip had no claim to the English throne if Mary died childless

  • England would not pass to Spain on Mary's death

    • This was the most important safeguard

England would not be obliged to fight in Philip's wars

  • This term was effectively set aside when Mary declared war on France in 1557 to support Philip

The marriage in practice

  • The marriage took place at Winchester Cathedral in July 1554

  • Philip was received coldly by the English public

    • He found England politically and socially unwelcoming and spent as little time there as possible

  • In 1554, Parliament rejected a bill that would have extended treason laws to include Philip, which would have made opposition to him equivalent to treason against the Crown

  • In 1555, Parliament prevented Philip's coronation as King of England

  • Philip became King of Spain in January 1556

    • From that point, England became more closely aligned with Spanish interests

  • Mary had two apparently false pregnancies, in 1554 and 1557

    • Both were deeply damaging to her credibility and authority, raising expectations that were then disappointed and weakening confidence in the regime

Examiner Tips and Tricks

Questions about the Spanish marriage reward precise knowledge of the treaty terms. The key analytical point is the gap between the treaty (which was carefully designed to protect England) and the reality (which was that Philip used England as a tool against France). Show that gap to build a strong argument.

The Wyatt Rebellion (1554): planned uprisings and movements of rebel forces towards London
  • Wyatt's rebellion was the most serious domestic challenge of Mary's reign

    • It came within weeks of the announcement of the Spanish marriage

Causes

  • The Spanish marriage was the primary cause

    • News of the planned marriage leaked in January 1554 and caused immediate alarm

    • There was fear that Philip would dominate English government despite the treaty's limits

    • There was widespread suspicion of foreign influence in English affairs

  • Protestant grievances also played a role, though their importance is debated

    • Some rebels were motivated by opposition to Mary's religious restoration

    • The government's own account emphasised religious motives, but this was propaganda designed to deflect attention

  • Economic and local factors in Kent also contributed

    • The cloth industry in Kent had been declining, creating economic hardship

    • Local gentry rivalries added to the tension

  • The plan:

    • Four simultaneous risings planned for March 1554: Devon (Carew), Leicestershire (Suffolk), Welsh Border (Croft) and Kent (Wyatt)

  • The aim was to replace Mary with Edward Courtenay, who would marry Princess Elizabeth

  • The conspiracy was discovered and the timeline was advanced to February to maintain surprise

Events

  • Three of the four risings failed to materialise

    • Only Wyatt raised enough men, around 3,000, in Kent

  • Wyatt marched his army towards London

    • London Bridge was closed against him

    • He moved west to Kingston to cross the Thames

  • Mary gave a famous speech at the Guildhall, refusing to flee and rallying Londoners to her cause

  • The City of London did not rise in support of Wyatt

    • Without the city, the rebellion had no hope

  • Wyatt surrendered

    • The rebellion collapsed within a week

Significance

  • Wyatt was executed

    • Lady Jane Grey and Guildford Dudley were also executed, in February 1554

    • Mary had been reluctant to execute Jane, seeing her as a figurehead rather than a genuine threat

    • However, Wyatt’s rebellion demonstrated that she could still be used as a focus for opposition, making her continued survival politically dangerous

  • Princess Elizabeth was imprisoned in the Tower on suspicion of involvement

    • She was released when no evidence of involvement was found

  • The rebellion was more dangerous than it appeared

    • Wyatt threatened the capital itself

  • It showed how quickly the Spanish marriage had converted popular support into suspicion

  • The failure of London to rise was the key factor in its defeat

    • Without the city, the rebellion could not succeed

  • Protestant resistance was limited without mass popular support

Examiner Tips and Tricks

Questions about Wyatt's Rebellion ask students to assess causes. The key debate is whether this was primarily an anti-Spanish rebellion or a Protestant one. The government's own propaganda said it was religious, but the government had a strong reason to frame it that way. The primary cause was the Spanish marriage. Be specific about the evidence for each cause.

Relations with Spain & France: The Loss of Calais, 1558

  • England's entry into the Habsburg-Valois War was the direct consequence of the Spanish marriage

    • It ended in the worst foreign policy disaster of the Tudor period

The Habsburg-Valois conflict

  • The dominant European conflict of the mid-16th century was between Habsburg Spain and Valois France

    • Henry VIII had been drawn into this conflict repeatedly at great expense

    • Northumberland had made peace with France in 1550 (Treaty of Boulogne), ending English involvement

  • Mary's marriage to Philip immediately re-entangled England with the Habsburg side

The road to war

  • Philip made no secret of wanting English military and financial support against France

  • Mary's own Council was divided

    • Many pointed out that the marriage treaty specified England was not obliged to fight in Philip's wars

  • Philip visited England briefly in 1557 to persuade Mary to declare war

  • Mary declared war on France in June 1557, sending English troops across the channel

  • English and Spanish forces together won the Battle of Saint-Quentin in August 1557

    • But Spain was financially exhausted and could not follow up the victory

The loss of Calais, January 1558

  • Calais had been in English hands since 1347, over 200 years

  • It was England's last territory in France and held enormous symbolic importance

  • French forces under the Duke of Guise launched a surprise attack in January 1558

    • The English garrison was outnumbered

    • Mary could not send adequate reinforcements in time

    • Calais fell within days

Why did the loss of Calais matter?

  • Symbolic significance

    • Calais was the last remnant of England's medieval empire in France

  • Strategic significance

    • It had served as a base for English military operations on the continent for generations

  • Political significance

    • It was a direct consequence of entering Philip's war

    • The English public drew this conclusion clearly

  • Personal significance

    • For Mary, it confirmed that the marriage had made England a tool of Spain, not a genuine partner

Examiner Tips and Tricks

The loss of Calais is often the endpoint of answers on Mary's foreign policy. Do not treat it as simply bad luck. It was a direct consequence of the Spanish marriage and the decision to join Philip's war against France. Showing that chain of causation is what makes an answer analytical rather than descriptive.

Problems of Succession under Mary I

  • The failure to produce a Catholic heir was the defining failure of Mary's reign

    • Everything she achieved was undone within a year of her death

Why was producing an heir so difficult?

  • Age:

    • Mary was 37 at accession

      • This was old by Tudor standards for beginning a reign and attempting pregnancy

  • Philip's absences:

    • He spent most of his time outside England, limiting any possibility of conception

  • Poor health:

    • Mary suffered recurring illness throughout her reign

  • Two false pregnancies:

    • In 1554 and 1557

    • Both were probably phantom pregnancies caused by serious illnesses (possibly uterine or ovarian cancer)

    • The 1554 pregnancy raised hopes across Catholic Europe

      • When it came to nothing, Mary's credibility was severely damaged

Elizabeth as successor

  • Under Henry VIII's will and the 1544 Succession Act, Elizabeth was next in line to the throne after Mary

  • To many contemporaries, Mary’s failure to produce an heir could also be interpreted as divine judgement on her policies, further weakening her religious authority

  • Mary deeply resented Elizabeth

    • She associated her with the breakdown of her parents' marriage (Elizabeth's mother was Anne Boleyn) and with Protestantism

  • Mary had Elizabeth imprisoned after Wyatt's Rebellion but could not prove her involvement

  • Pressure from Philip and from the Council forced Mary to accept that Elizabeth must succeed

  • Philip actively lobbied for Elizabeth's release from the Tower in 1554

    • His reasons were strategic

      • He needed England to remain within the Habsburg sphere of influence after Mary's death

  • Mary named Elizabeth as her successor six days before her death on 6 November 1558

Philip and the succession

  • Philip's attitude to the succession was calculating rather than hostile

    • He needed England to remain an ally after Mary's death

    • He feared that England might pass to the French-backed Mary Queen of Scots if Elizabeth was excluded

    • He later proposed marriage to Elizabeth himself after Mary's death

      • A sign of how strategically important England remained to Spain

Why did the failure of the succession matter?

  • Mary's entire religious and political project depended on a Catholic heir

    • Without one, Protestant Elizabeth would succeed and reverse everything

    • This is exactly what happened

      • Within a year of Mary's death, the Elizabethan Settlement had restored Protestant worship

  • The Spanish marriage, specifically designed to solve the succession problem, failed in its primary purpose

Examiner Tips and Tricks

The succession is sometimes treated as a separate topic from foreign policy. In this reign, they are inseparable. The marriage was about the succession, the war was about the marriage, the loss of Calais was about the war. Showing how these things are interconnected is what makes a strong argument.

How Successfully Did Mary I Handle Foreign Policy and the Succession?

  • Use the evidence below to build your own argument

  • Consider aims, outcomes and the constraints Mary faced

Evidence that Mary handled foreign policy and succession poorly

  • The Spanish marriage alienated popular opinion almost immediately

    • Wyatt's Rebellion followed within months

  • The marriage treaty was effectively overridden

    • England was drawn into Philip's war against France despite the treaty’s intention to protect England from being drawn into Habsburg wars

  • Calais was lost

    • England's last French territory, held for over 200 years (since 1347), was lost as a direct consequence of joining Philip's war

  • No heir was produced

    • The fundamental purpose of the marriage was not achieved

  • Elizabeth succeeded

    • Mary failed to secure a Catholic succession, and Protestant Elizabeth succeeded

  • Philip used England as a tool against France rather than as a genuine partner

    • The marriage served Spanish interests more than English ones

Evidence that Mary faced impossible constraints

  • Any Tudor monarch needed to marry and produce an heir

    • For Mary, the pressure was even greater: without an heir, Protestant Elizabeth would succeed

  • The marriage treaty was a genuine attempt to protect English sovereignty

    • Its failure reflects Philip's power, not Mary's lack of effort

  • Wyatt's Rebellion was defeated

    • Mary's personal courage at the Guildhall was decisive

    • The rebellion collapsed within a week

  • Calais was increasingly difficult and expensive to defend in the long term

  • The Elizabethan Settlement reversed Mary's work so quickly partly because Mary died young

    • Had she lived longer, the religious restoration may have taken deeper root

  • Mary faced a unique combination of challenges, including female rule, religious reversal and dependence on a foreign husband

Examiner Tips and Tricks

Questions on Mary's foreign policy often carry a judgemental framing. Be specific about which failures were the result of Mary's decisions and which were the result of constraints she could not control. The marriage was her choice, Philip's absences were not. The loss of Calais followed from entering a war she did not have to enter. These distinctions matter.
