County of Champagne in the context of "Joan II of Navarre"

The Champagne fairs were an annual cycle of trade fairs which flourished in different towns of the County of Champagne in Northeastern France in the 12th and 13th centuries, originating in local agricultural and stock fairs. Each fair lasted about two to three weeks. The Champagne fairs, sited on ancient land routes and largely self-regulated through the development of the Lex mercatoria ("merchant law"), became an important engine in the reviving economic history of medieval Europe, "veritable nerve centers" serving as a premier market for textiles, leather, fur, and spices. At their height, in the late 12th and the 13th century, the fairs linked the cloth-producing cities of the Low Countries with the Italian dyeing and exporting centers, with Genoa in the lead, dominating the commercial and banking relations operating at the frontier region between the north and the Mediterranean. The Champagne fairs were one of the earliest manifestations of a linked European economy, a characteristic of the High Middle Ages.

Marie of France (1145 – 11 March 1198) was a Capetian princess who became Countess of Champagne by her marriage to Henry I of Champagne. She ruled the County of Champagne as regent during Henry I's absence from 1179 to 1181; during the minority of their son Henry II from 1181 to 1187; and during Henry II's absence from 1190 to 1197. She was the daughter of Eleanor of Aquitaine and Louis VII of France.

The first known lord of Joinville (French sire or seigneur de Joinville) in the county of Champagne appears in the middle of the eleventh century. The former lordship was raised into the Principality of Joinville under the House of Guise by French king Henry II in 1551, and passed to the House of Orléans in 1688. Even though the principality was abolished with the end of the French monarchy, the title Prince of Joinville (French Prince de Joinville) continued to be used as a courtesy title.

Geoffrey I of Villehardouin (French: Geoffroi I de Villehardouin) (c. 1169 – c. 1229) was a French knight from the County of Champagne who joined the Fourth Crusade. He participated in the conquest of the Peloponnese and became the second prince of Achaea (1209/1210–c. 1229).

Under his reign, the Principality of Achaea became the direct vassal of the Latin Empire of Constantinople. He extended the borders of his principality.

The count of Champagne was the ruler of the County of Champagne from 950 to 1316. Champagne evolved from the County of Troyes in the late eleventh century and Hugh I was the first to officially use the title count of Champagne.

Count Theobald IV of Champagne inherited the Kingdom of Navarre in 1234. His great-granddaughter Joan married King Philip IV of France. Upon Joan's death in 1305, their son Louis became the last independent count of Champagne, with the title merging into the royal domain upon his accession to the French throne in 1314.

Champagne (French pronunciation: [ʃɑ̃paɲ] ) was a province in the northeast of the Kingdom of France, now best known as the Champagne wine region for the sparkling white wine that bears its name in modern-day France. The County of Champagne, descended from the early medieval kingdom of Austrasia, passed to the French crown in 1314.

Formerly ruled by the counts of Champagne, its western edge is about 160 km (100 miles) east of Paris. The cities of Troyes, Reims, and Épernay are the commercial centers of the area. In 1956, most of Champagne became part of the French administrative region of Champagne-Ardenne, which comprised four departments: Ardennes, Aube, Haute-Marne, and Marne. From 1 January 2016, Champagne-Ardenne merged with the adjoining regions of Alsace and Lorraine to form the new region of Grand Est.

Theobald III of Blois (French: Thibaut; 1012–1089) was count of Blois, Meaux and Troyes. He was captured in 1044 by Geoffrey II, Count of Anjou, and exchanged the County of Touraine for his freedom. Theobald used his nephew's involvement with the Norman invasion of England to gain authority over the County of Champagne. He died in 1089.

The County of Blois was a feudal principality centred on Blois, south of Paris, France. It was created just after king Clovis I conquered Roman Gaul around AD 500. Between the 8th and the 13th centuries, it was amongst the most powerful vassal counties within the Kingdom of France, after having succeeded in surrounding the Capetian dynasty's lands of France since Blois annexed the Champagne.

Since its creation up to 1498, the county was directed by counts, often with various more or less prestigious titles of nobility, or sometimes delegating their task to viscounts. The county existed until its definitive attachment to the Kingdom's lands in 1660, when Gaston, Duke of Orléans and last count of Blois, died.
