Conquest of Wales of 1267: Llywelyn ap Gruffudd enjoyed a temporary advantage after the Barons' War. The 1267 Treaty of Montgomery recognised his ownership of land he had conquered in the Four Cantrefs of Perfeddwlad and his title of Prince of Wales. However, his administration was heavy-handed and unpopular, especially among Welshmen on the Marches, where Llywelyn resorted to hostage-taking and intimidation to retain his domination. He also entered into a damaging conflict with the Welsh church, further undermining his authority. Armed conflicts continued on the March. In 1272 Llywelyn suffered a major defeat to the Earl of Gloucester, Gilbert de Clare, and was forced to evacuate south-east Wales. This setback triggered a failed attempt to assassinate the prince, exposing divisions in his principality. The chief suspects, his younger brother Dafydd and Gruffudd ap Gwenwynwyn of Powys, fled to take refuge at the English court. Citing ongoing hostilities and Edward's harbouring of his enemies, Llywelyn refused to do homage to the King. For Edward, a further provocation came from Llywelyn's planned marriage to Eleanor, daughter of Simon de Montfort the Elder. Llywelyn was also suspected of planting a Montfortian spy, Nicholas Waltham, at Edward’s court, and intriguing with Eleanor’s brothers, Simon the Younger and Guy. In November 1276, Edward declared war. Initial operations were under the captaincy of Mortimer, Edward's brother Edmund, Earl of Lancaster, and
William de Beauchamp, 9th Earl of Warwick. In July 1277 Edward invaded with a force of 15,500, of whom 9,000 were Welsh. The campaign never came to a major battle, and Llywelyn realised he had no choice but to surrender. War broke out again in 1282. The Welsh saw the war as being over national identity and the right to traditional Welsh law. This enjoyed wide support, provoked by attempts to abuse the English legal system to dispossess prominent Welsh landowners, many of whom were Edward's former opponents. For Edward, it became a war of conquest aimed to "put an end finally to … the malice of the Welsh". The war started with a rebellion by Dafydd, who was discontented with the reward he had received in 1277. Llywelyn and other Welsh leaders soon joined in, and initially the Welsh attack was successful. In June, Gloucester was defeated at the
Battle of Llandeilo Fawr. On 6 November, while
John Peckham, Archbishop of Canterbury, was conducting peace negotiations, Edward's commander of
Anglesey,
Luke de Tany, carried out a surprise attack. A
pontoon bridge had been built to the mainland, but shortly after Tany and his men crossed over, they were ambushed by the Welsh and suffered heavy losses at the
Battle of Moel-y-don. The Welsh advances ended on 11 December, when Llywelyn was lured into a trap and killed at the
Battle of Orewin Bridge. The conquest of Gwynedd was complete with the capture in June 1283 of Dafydd, who was taken to
Shrewsbury and executed as a traitor the following year; Edward ordered Dafydd's head to be publicly exhibited on
London Bridge. , one of the castles erected in Wales during the reign ofEdward I By the 1284
Statute of Rhuddlan, the
principality of Wales was incorporated into England and was given an administrative system like the English, with counties policed by sheriffs. English law was introduced in criminal cases; the Welsh were allowed to maintain their own customary laws in some cases of property disputes. After 1277, and increasingly after 1283, Edward embarked on a project of English settlement of Wales, creating new towns like
Flint,
Aberystwyth and
Rhuddlan. Their new residents were English migrants, the local Welsh being banned from living there, and many were protected by extensive walls. An extensive project of castle building was also initiated, under the direction of
James of Saint George, a prestigious architect Edward had met in Savoy on his return from the crusade. These included
Beaumaris,
Caernarfon,
Conwy and
Harlech castles, intended to act as fortresses, royal palaces and as the new centres of civilian and judicial administration. His programme of castle building in Wales heralded the widespread introduction of
arrowslits in castle walls across Europe, drawing on Eastern architectural influences. Also a product of the Crusades was the introduction of the
concentric castle, and four of the eight castles Edward founded in Wales followed this design. The castles drew on imagery associated with the
Byzantine Empire and
King Arthur in an attempt to build legitimacy for his new rule, and they made a clear statement about Edward's intention to rule Wales permanently. The Welsh aristocracy were nearly wholly dispossessed of their lands. Edward was the greatest beneficiary of this process. Localised rebellions occurred in 1287–88, partly caused by Edward failing to reward former Welsh allies.
A more serious revolt came in 1294, under the leadership of
Madog ap Llywelyn, a distant relative of Llywelyn ap Gruffudd. The causes of the 1294 revolt included resentment at the occupation, poor, colonial-style governance, and very heavy taxation. This last conflict demanded the King's attention, but in both cases the rebellions were put down. The revolt was followed by immediate punitive measures including taking 200 hostages. Measures to stop the Welsh from bearing arms or living in the new boroughs probably date from this time, and the Welsh administration continued to be nearly wholly imported. In 1284, King Edward had his son Edward (later
Edward II) born at Caernarfon Castle, probably to make a statement about the new political order in Wales. In 1301 at Lincoln, the young Edward became the first English prince to be invested as Prince of Wales, when the King granted him the Earldom of Chester and lands across North Wales, hoping to give his son more financial independence. Edward began a more conciliatory policy to rebuild systems of patronage and service, particularly through his son as Prince of Wales, but Wales remained politically volatile, and a deep distrust remained between the English settlers and the Welsh.
Diplomacy and war on the Continent (left). As
Duke of Aquitaine, Edward was a
vassal of the French king. Edward never again went on crusade after his return to England in 1274, but he maintained an intention to do so, and in 1287 took a vow to go on another crusade. This intention guided much of his foreign policy, until at least 1291. To stage a European-wide crusade, it was essential to prevent conflict between the sovereigns on
Continental Europe. A major obstacle to this was the conflict between the French
Capetian House of Anjou ruling southern Italy and the Crown of Aragon in Spain. In
the war that followed, Charles of Anjou's son,
Charles of Salerno, was taken prisoner by the Aragonese. The French began planning an attack on Aragon, raising the prospect of a large-scale European war. To Edward, it was imperative that such a war be avoided, and in Paris in 1286 he brokered a truce between France and Aragon that helped secure Charles's release. As far as the crusades were concerned, Edward's efforts proved ineffective. A devastating blow to his plans came in 1291, when the Mamluks
captured Acre, the last Christian stronghold in the Holy Land. Edward had long been deeply involved in the affairs of his own Duchy of Gascony. In 1278 he assigned an investigating commission to his trusted associates
Otto de Grandson and the
chancellor Robert Burnell, which caused the replacement of the
seneschal Luke de Tany. In 1286, Edward visited the region and stayed for almost three years. On Easter Sunday 1287, Edward was standing in a tower when the floor collapsed. He fell 80 feet, broke his collarbone, and was confined to bed for several months. Several others died. Soon after he regained his health, he ordered the local Jews expelled from Gascony, seemingly as a "thank-offering" for his recovery. The perennial problem was the status of Gascony within the Kingdom of France, and Edward's role as the French king's vassal. On his diplomatic mission in 1286, Edward had paid homage to the new king,
PhilipIV. Following an outbreak of piracy and informal war between English, Gascon, Norman, and French sailors in 1293, his brother Edmund Crouchback allowed Philip IV to occupy Gascony's chief fortresses as a show of good faith that Edward had not intended the seizure of several French ships or the sacking of the French port of
La Rochelle. Philip refused to release the fortresses, and declared Gascony forfeit when Edward refused to appear before him again in Paris. Correspondence between Edward and the
Mongol court of the east continued during this time. Diplomatic channels between the two had begun during Edward's time on crusade, regarding a possible alliance to retake the Holy Land for Europe. Edward received Mongol envoys at his court in Gascony while there in 1287, and one of their leaders,
Rabban Bar Sauma (a
Uyghur Turk from
Yuan China), recorded an extant account of the interaction. Edward responded favourably, declaring his intent to travel to the east once he obtained papal approval. This did not materialise, but the King's decision to send
Geoffrey of Langley as his ambassador to the Mongols showed that he was seriously considering the prospective Mongol alliance. Eleanor of Castile died on 28 November 1290. The couple loved each other, and like his father, Edward was very devoted to his wife and was faithful to her throughout their marriage. He was deeply affected by her death, and displayed his grief by ordering the construction of twelve so-called
Eleanor crosses, one at each place where her funeral cortège stopped for the night. In 1294 a war at sea flared up between English and Norman privateers. Philip the Fair exploited the conflict to confiscate Gascony, provoking Edward to renounce his homage and declare war. After the initial fighting in Gascony, both kings sought to widen the conflict by forging expensive alliances. Edward joined forces with
Adolf of Nassau (the King of Germany), the
Count of Flanders and the barons of
Franche-Comté in eastern
Burgundy. Other members of the alliance included two of his sons-in-law, the
Duke of Brabant and the Count of
Bar-le-Duc. Edward's strategy was to attack the French on all fronts and stretch their forces to their breaking point. Most of his allies did indeed go into action and caused considerable damage in
Champagne, Burgundy, Gascony and the
Toulousaine. However, the King of Germany failed to join Edward in Flanders, obliging the allies to seek a truce in October 1297. Edward renewed his military contract with the Burgundians in March 1298, prolonging the war in Franche-Comté. This may have been an effort to distract Philip and prevent him from aiding the Scots. The war was effectively frozen by the
Treaties of Montreuil in 1299, whereby Edward agreed to marry Philip's sister Margaret. As part of her dowry Philip returned the county of Ponthieu, which had been seized along with Gascony in 1294. This restored Edward's position as a vassal of the French king, although Gascony was not formally returned until the 1303 Treaty of Paris.
Great Cause in
Westminster Abbey was commissioned by Edward in 1296 to house the
Stone of Scone and has been used for coronations for over 700 years. The relationship between England and Scotland by the 1280s was one of relatively harmonious coexistence. The issue of homage did not reach the same level of controversy as it did in Wales; in 1278 King
Alexander III of Scotland paid homage to Edward, who was his brother-in-law, but apparently only for the lands he held in England. Problems arose only with the Scottish succession crisis of the early 1290s. When Alexander died in 1286, he left as heir to the Scottish throne
Margaret, his three-year-old granddaughter and sole surviving descendant. By the
Treaty of Birgham, it was agreed that Margaret should marry King Edward's six-year-old son
Edward of Caernarfon, though Scotland would remain free of English
overlordship. Margaret, by now seven, sailed from Norway for Scotland in late 1290, but fell ill on the way and died in
Orkney. This left the country without an obvious heir, and led to the succession dispute known as the
Great Cause. The Scottish magnates made a request to Edward to conduct the proceedings and administer the outcome, but not to arbitrate in the dispute. The actual decision would be made by 104 auditors40 appointed by Balliol, 40 by Brus and the remaining 24 selected by Edward from senior members of the Scottish political community. At Birgham, with the prospect of a personal union between the two realms, the question of suzerainty had not been of great importance to Edward. Now he insisted that, if he were to settle the contest, he had to be fully recognised as Scotland's feudal overlord. The Scots were reluctant to make such a concession, and replied that since the country had no king, no one had the authority to make this decision. This problem was circumvented when the competitors agreed that the realm would be handed over to Edward until a rightful heir had been found. After a lengthy hearing, a decision was made in favour of John Balliol on 17 November 1292. A further provocation came in a case brought by Macduff, son of
Malcolm II, Earl of Fife, in which Edward demanded that Balliol appear in person before the
English Parliament to answer the charges. This the Scottish King did, but the final straw was Edward's demand that the Scottish magnates provide military service in the war against France. This was unacceptable; the Scots instead formed an
alliance with France and launched an unsuccessful attack on
Carlisle. Edward responded by invading Scotland in 1296 and taking the town of
Berwick-upon-Tweed which included the
massacre of civilians. At the
Battle of Dunbar, Scottish resistance was effectively crushed. Edward took the
Stone of Destiny – the Scottish coronation stoneand brought it to Westminster, placing it in what became known as
King Edward's Chair; he deposed Balliol and placed him in the
Tower of London, and installed Englishmen to govern the country. The campaign had been very successful, but the English triumph would be only temporary. ==Government and law==
