Answer the following question: Information: - Llywelyn ap Gruffudd (c. 1223 11 December 1282), sometimes written as Llywelyn ap Gruffydd, also known as Llywelyn the Last, or, in Welsh, Llywelyn Ein Llyw Olaf, was Prince of Wales (Latin; "Princeps Wallie", Welsh; "Tywysog Cymru") from 1258 until his death at Cilmeri in 1282. The son of Gruffudd ap Llywelyn Fawr and grandson of Llywelyn the Great, he was the last sovereign prince of Wales before its conquest by Edward I of England. - The Hundred Years' War was a series of conflicts waged from 1337 to 1453 by the House of Plantagenet, rulers of the Kingdom of England, against the House of Valois, rulers of the Kingdom of France, over the succession of the French throne. Each side drew many allies into the war. It was one of the most notable conflicts of the Middle Ages, in which five generations of kings from two rival dynasties fought for the throne of the largest kingdom in Western Europe. The war marked both the height of chivalry and its subsequent decline, and the development of strong national identities in both countries. - Jean Froissart (Old French, Middle French "Jehan", ) was a French-speaking medieval author and court historian from the Low Countries, who wrote several works, including "Chronicles" and "Meliador", a long Arthurian romance, and a large body of poetry, both short lyrical forms, as well as longer narrative poems. For centuries, "Froissart's Chronicles" have been recognised as the chief expression of the chivalric revival of the 14th century Kingdom of England and Kingdom of France. His history is also an important source for the first half of the Hundred Years' War. - Joan , LG , suo jure 4th Countess of Kent , 5th Baroness Wake of Liddell ( 19 September 1328 -- 7 August 1385 ) , known to history as The Fair Maid of Kent , was the first post-conquest Princess of Wales as wife to Edward , the Black Prince , son and heir of King Edward III. Although the French chronicler Jean Froissart called her '' the most beautiful woman in all the realm of England , and the most loving '' , the appellation '' Fair Maid of Kent '' does not appear to be contemporary . Joan assumed the title of 4th Countess of Kent and 5th Baroness Wake of Liddell after the death of her brother , John , in 1352 . - Princess of Wales is a British courtesy title held by the wife of the Prince of Wales, who is, since the 14th century, the heir apparent of the English or British monarch. The first acknowledged title holder was Eleanor de Montfort, wife of Llywelyn ap Gruffudd. It has subsequently been used by wives of post-conquest princes of Wales.
