Treaty of Gwerneigron

Last updated

The Treaty of Gwerneigron was a peace treaty signed by Henry III, king of England and Dafydd ap Llywelyn, prince of Wales of the House of Gwynedd, on 29 August 1241. The treaty brought to an end Henry's invasion of Wales begun earlier that month.

In it, and the Treaty of London which followed in October, Dafydd agreed to cede large parts of modern-day Flintshire to Henry. The treaty also obliged Dafydd to hand over his half-brother, Gruffudd ap Llywelyn Fawr, to Henry, who promptly imprisoned him in the Tower of London. Given that Gruffudd was a rival claimant to Dafydd's princeship, Henry reasoned that Dafydd's authority could be curbed by the ever-present threat that Gruffudd might be released and sent to Wales to undermine Dafydd's position. Dafydd promised his and his own heirs' loyalty to kings of England so that in the event of breach he would forfeit all the remaining lands to the king. The king also became Dafydd's heir in case the latter died without living offspring.

The treaty effectively prevented Dafydd from pressing his rights to the territories controlled by his father Llywelyn until Gruffudd's death during an escape attempt on 1 March 1244, after which Dafydd invaded Flintshire and recovered his lost territory.

The history of what is now Wales begins with evidence of a Neanderthal presence from at least 230,000 years ago, while Homo sapiens arrived by about 31,000 BC. However, continuous habitation by modern humans dates from the period after the end of the last ice age around 9000 BC, and Wales has many remains from the Mesolithic, Neolithic, and Bronze Age. During the Iron Age the region, like all of Britain south of the Firth of Forth, the culture had become Celtic, with a common Brittonic language. The Romans, who began their conquest of Britain in AD 43, first campaigned in what is now northeast Wales in 48 against the Deceangli, and gained total control of the region with their defeat of the Ordovices in 79. The Romans departed from Britain in the 5th century, opening the door for the Anglo-Saxon settlement. Thereafter, the culture began to splinter into a number of kingdoms. The Welsh people formed with English encroachment that effectively separated them from the other surviving Brittonic-speaking peoples in the early middle ages.

The Principality of Wales was originally the territory of the native Welsh princes of the House of Aberffraw from 1216 to 1283, encompassing two-thirds of modern Wales during its height of 1267–1277. Following the conquest of Wales by Edward I of England of 1277 to 1283, those parts of Wales retained under the direct control of the English crown, principally in the north and west of the country, were re-constituted as a new Principality of Wales and ruled either by the monarch or the monarch's heir though not formally incorporated into the Kingdom of England. This was ultimately accomplished with the Laws in Wales Acts 1535–1542 when the Principality ceased to exist as a separate entity.

<span class="mw-page-title-main">History of Gwynedd during the High Middle Ages</span>

The history of Gwynedd in the High Middle Ages is a period in the History of Wales spanning the 11th through the 13th centuries. Gwynedd, located in the north of Wales, eventually became the most dominant of Welsh polities during this period. Contact with continental courts allowed for Gwynedd to transition from a petty kingdom into an increasingly sophisticated principality of seasoned courtiers capable of high level deplomacy and representation; not only with the Angevine kings, but also the king of France and the Papal See. Distinctive achievements in Gwynedd include further development of Medieval Welsh literature, particularly poets known as the Beirdd y Tywysogion associated with the court of Gwynedd; the reformation of bardic schools; and the continued development of Cyfraith Hywel. All three of these further contributed to the development of a Welsh national identity in the face of Anglo-Norman encroachment of Wales.
