WThe Treaty of Aberconwy was signed in 1277 by King Edward I of England and Llewelyn the Last, Prince of Wales, following Edward’s invasion of Llewelyn’s territories earlier that year. The treaty granted peace between the two but also essentially guaranteed that Welsh self-rule would end upon Llewelyn's death and represented the completion of the first stage of the Conquest of Wales by Edward I.
WThe Boulogne agreement was a document signed by a group of English magnates in 1308, concerning the government of Edward II. After the death of Edward I in 1307, discontent soon developed against the new king. This was partly due to lingering problems from the previous reign, but also related to issues with Edward II himself. Particularly his abandonment of the Scottish Wars and his patronage of the unpopular Piers Gaveston caused discontent. Drawn up in Boulogne-sur-Mer during the king's nuptials, the document vaguely asserted the signatories' duty to guard the rights of the Crown. Three months later, the agreement was the basis for another document, justifying opposition to the king. This latter document, the so-called Declaration of 1308, is notable for its use of the "doctrine of capacities": the distinction between the person of the King and the institution of the Crown.
WThe Dictum of Kenilworth, issued on 31 October 1266, was a pronouncement designed to reconcile the rebels of the Second Barons' War with the royal government of England. After the baronial victory at the Battle of Lewes in 1264, Simon de Montfort took control of royal government, but at the Battle of Evesham the next year Montfort was killed, and King Henry III restored to power. A group of rebels held out in the stronghold of Kenilworth Castle, however, and their resistance proved difficult to crush.
WIn July 1482 an English army invaded Scotland during the Anglo-Scottish Wars. The town of Berwick-upon-Tweed and its castle were captured and the English army briefly occupied Edinburgh. These events followed the signing of the Treaty of Fotheringhay, 11 June 1482, in which Alexander Stewart, Duke of Albany, the brother of James III of Scotland declared himself King of Scotland and swore loyalty to Edward IV of England. The follow-up invasion of Scotland under the command of Edward's brother, Richard, Duke of Gloucester failed to install Albany on the throne, but Berwick has remained English ever since the castle surrendered on 24 August. The English army left Edinburgh with a promise for the repayment of the dowry paid for the marriage of Princess Cecily of England to the Scottish Prince.
WThe Mise of Amiens [miz ɒv a.mjɛ̃] was a settlement given by King Louis IX of France on 23 January 1264 in the conflict between King Henry III of England and his rebellious barons, led by Simon de Montfort. Louis' one-sided decision for King Henry led directly to the hostilities of the Second Barons' War.
WThe Mise of Lewes was a settlement made on 14 May 1264 between King Henry III of England and his rebellious barons, led by Simon de Montfort. The settlement was made on the day of the Battle of Lewes, one of the two major battles of the Second Barons' War. The conflict between king and magnates was caused by dissatisfaction with the influence of foreigners at court and Henry's high level and new methods of taxation. In 1258 Henry was forced to accept the Provisions of Oxford, which essentially left the royal government in the hands of a council of magnates, but this document went through a long series of revocations and reinstatements. In 1263, as the country was on the brink of civil war, the two parties agreed to submit the matter to arbitration by the French king Louis IX. Louis was a firm believer in the royal prerogative, and decided clearly in favour of Henry. The outcome was unacceptable for the rebellious barons, and war between the two parties broke out almost immediately.
WThe Treaty of Montgomery was an Anglo-Cambrian treaty signed on 29 September 1267 in Montgomeryshire by which Llywelyn ap Gruffudd was acknowledged as Prince of Wales by King Henry III of England. It was the only time an English ruler recognised the right of a ruler of Gwynedd over Wales. Llywelyn's grandfather Llywelyn the Great had previously laid claim to be the effective prince of Wales by using the title "Prince of Aberffraw, Lord of Snowdon" in the 1230s, after subduing all the other Welsh dynasties. Likewise Llywelyn's uncle, Dafydd ap Llywelyn, claimed the title of Prince of Wales during his reign from 1240 to 1246. However, Llywelyn's supremacy in the late 1260s forced recognition of his authority in Wales by an English Crown weakened by internal division.
WThe Treaty of Newcastle was a treaty signed between King Edward III of England and King Edward Balliol of Scotland on 12 June 1334.
WThe Treaty of Paris was a treaty between Louis IX of France and Henry III of England, agreed to on 4 December 1259, ending 100 years of conflicts between the Capetian and Plantagenet dynasties.
WThe Treaty of Tours was an attempted peace agreement between Henry VI of England and Charles VII of France, concluded by their envoys on 28 May 1444 in the closing years of the Hundred Years' War. The terms stipulated the marriage of Charles VII's niece, Margaret of Anjou, to Henry VI, and the creation of a truce of two years – later extended – between the kingdoms of England and France. In exchange for the marriage, Charles wanted the English-held area of Maine in northern France, just south of Normandy.
WThe Treaty of Brétigny was a treaty, drafted on 8 May 1360 and ratified on 24 October 1360, between King Edward III of England and King John II of France. In retrospect, it is seen as having marked the end of the first phase of the Hundred Years' War (1337–1453) as well as the height of English power on the European continent.
WThe Treaty of Canterbury was a diplomatic agreement concluded between Sigismund, Holy Roman Emperor, and King Henry V of England on 15 August 1416. The treaty resulted in a defensive and offensive alliance against France.

WThe Treaty of Wallingford, also known as the Treaty of Winchester or the Treaty of Westminster, was an agreement reached in England in the summer of 1153. It effectively ended a civil war known as the Anarchy (1135–54), caused by a dispute over the English crown between King Stephen and his cousin Empress Matilda. The Treaty of Wallingford allowed Stephen to keep the throne until his death, but ensured that he would be succeeded by Matilda's son Henry II.
WThe Treaty of Westminster was signed on 13 February 1462 between Edward IV of England of the House of York and the Scottish John of Islay, Earl of Ross, Lord of the Isles. The agreement proposed that if Scotland was conquered by England, the lands north of the Scottish sea would be divided between the Lord of the Isles and the Earl of Douglas to be held from the crown of England, while the Earl of Douglas would hold Scotland south of the Firth.
WThe Treaty of Windsor is the diplomatic alliance signed between Portugal and England on 9 May 1386 at Windsor and sealed by the marriage of King John I of Portugal to Philippa of Lancaster, daughter of John of Gaunt, 1st Duke of Lancaster. With the victory at the Battle of Aljubarrota, assisted by English archers, John I was recognised as the undisputed King of Portugal, putting an end to the interregnum of the 1383–1385 Crisis. The Treaty of Windsor established a pact of mutual support between the countries.
WThe Treaty of York (1464) was made between England and Scotland on 1 June 1464 at York and was intended to establish 15 years of peace. Previously Scotland had supported the defeated House of Lancaster in the English civil War of the Roses.
