Eugène Emmanuel Viollet-le-Duc (French: [øʒɛn vjɔlɛ lə dyk]; 27 January 1814 – 17 September 1879) was a French architect and author, famous for his restoration of the most prominent medieval landmarks in France. His major restoration projects included Notre-Dame de Paris, the Basilica of Saint Denis, Mont Saint-Michel, Sainte-Chapelle, the medieval walls of the city of Carcassonne, and Château de Roquetaillade in the Bordeaux region.

His writings on decoration and on the relationship between form and function in architecture had a fundamental influence on a whole new generation of architects, including all the major Art Nouveau artists: Antoni Gaudí, Victor Horta, Hector Guimard, Henry van de Velde, Henri Sauvage and the École de Nancy, Paul Hankar, Otto Wagner, Eugène Grasset, Émile Gallé, and Hendrik Petrus Berlage. He also influenced the first modern architects, Frank Lloyd Wright, Mies van der Rohe, Auguste Perret, Louis Sullivan, and Le Corbusier, who considered Viollet-le-Duc as the father of modern architecture. English architect William Burges claimed that "We all cribbed on Viollet-le-Duc even though no one could read French".

Narbonne (/nɑːrˈbɒn/ nar-BON, US also /-ˈbɔːn, -ˈbʌn/ -⁠BAWN, -⁠BUN, French: [naʁbɔn] ; Occitan: Narbona [naɾˈβunɔ]; Latin: Narbo [ˈna(ː)rboː]; Late Latin: Narbona) is a commune in southeastern France, located in the Occitanie region. The city lies 849 km (528 mi) from Paris in the Aude department, of which it is a sub-prefecture. It is located about 15 km (9 mi) from the shores of the Mediterranean Sea and was historically a prosperous port. From the 14th century it declined following a change in the course of the river Aude. While it is the largest commune in Aude, the capital of the Aude department is the smaller commune of Carcassonne.

Aude (/oʊd/ OHD; French: [od] ; Occitan: [ˈawðe]) is a department in southern France, located in Occitania and named after the river Aude. The departmental council also calls it "Cathar Country" (French: Pays cathare) after a group of religious dissidents active in the 12th to 14th centuries.

Its prefecture is Carcassonne and its subprefectures are Limoux and Narbonne. As of 2019, it had a population of 374,070. Aude is a frequent feminine French given name in Francophone countries, deriving initially from Aude or Oda, a wife of Bertrand, Duke of Aquitaine, and mother of Eudo, brother of Saint Hubertus. Aude was the name of Roland's fiancée in the chansons de geste.

Edward of Woodstock (15 June 1330 – 8 June 1376), known as the Black Prince, was the eldest son and heir apparent of King Edward III of England. He died before his father and so his son, Richard II, succeeded to the throne instead. Nevertheless, Edward earned distinction as one of the most successful English commanders during the Hundred Years' War, being regarded by his English contemporaries as a model of chivalry and one of the greatest knights of his age. Edward was made Duke of Cornwall, the first English dukedom, in 1337. He was guardian of the kingdom in his father's absence in 1338, 1340, and 1342. He was created Prince of Wales in 1343 and knighted by his father at La Hougue in 1346.

In 1346, Prince Edward commanded the vanguard at the Battle of Crécy, his father intentionally leaving him to win the battle. He took part in Edward III's 1349 Calais expedition. In 1355, he was appointed the king's lieutenant in Gascony and ordered to lead an army into Aquitaine on a chevauchée, during which he pillaged Avignonet and Castelnaudary, sacked Carcassonne, and plundered Narbonne. In 1356, on another chevauchée, he ravaged Auvergne, Limousin, and Berry but failed to take Bourges. The forces of King John II of France met Edward's armies near the city of Poitiers. After negotiations between the two sides broke down, the Anglo-Gascon forces under Edward routed the French army and captured King John at the Battle of Poitiers.

Simon de Montfort, 5th Earl of Leicester (c. 1175 – 25 June 1218), known as Simon IV (or V) de Montfort and as Simon de Montfort the Elder, was a French nobleman and knight of the early 13th century. He is widely regarded as one of the great military commanders of the Middle Ages. He took part in the Fourth Crusade and was one of the prominent figures of the Albigensian Crusade. Montfort is mostly noted for his campaigns in the latter, notably for his battle at Muret. He died at the Siege of Toulouse in 1218. He was Lord of Montfort from 1188 to his death and Earl of Leicester in England from 1204. He was also Viscount of Albi, Béziers and Carcassonne from 1213, as well as Count of Toulouse from 1215.
