County of Champagne

The County of Champagne (Latin: Comitatus Campaniensis; Old French: Conté de Champaigne) was a medieval territory and feudal principality in the Kingdom of France. It developed on the rich plains between Paris and the border of the Holy Roman Empire in the 12th century. It became an economic hub of northern France and an international trade center in part due to the trade fairs instituted by Count Theobald II, and steady land clearing led to economic and urban growth. Count Henry the Liberal established the city of Troyes as the county's capital and expanded the state. The court of Champagne under Count Henry and Countess Marie saw a proliferation of literary authors. In the 13th century, Count Theobald III, Countess Blanche, and Count Theobald IV oversaw a centralization of the state. The county is noted for its support to the crusades and monastic foundations, especially those of the Cistercians, which originated within its borders. From 1234 the count of Champagne was also the king of Navarre, and the marriage of Queen Joan I of Navarre with King Philip IV of France led to the county being absorbed into the royal domain of the kings of France in the 14th century.

The name of the county, Champagne, comes from the vast open lands (campi) between the rivers Aisne, Meuse, and Yonne east of the city of Paris. This area of the medieval Kingdom of France was a highly fragmented frontier zone between the domain of the king of France and the Holy Roman Empire. The long process of consolidation of the county began in 1021 when Count Odo II of Blois (r. 996–1037) inherited the counties of Meaux and Troyes along with a number of lesser lordships. Count Theobald III of Blois divided his possessions between his sons. By 1100 the youngest, Hugh, inherited Troyes from his father and Bar-sur-Aube and Vitry from his mother, Adele of Valois; these three counties formed the core of the County of Champagne. Hugh called himself variously count of Troyes and count of Champagne.

The lands of southern Champagne and Brie coalesced under Count Theobald II (r. 1120–1152). Theobald encouraged the immigration of settlers and merchants, leading to the development of the sparsely populated countryside and the growth of towns. Theobald did homage for Troyes to Duke Odo II of Burgundy; for Blois and Meaux he may have done homage to King Louis VII of France; and for smaller holdings to the archbishop of Reims and the bishop of Langres. Nevertheless, Champagne remained a collection of lordships rather than a single entity during Theobald's rule and only gained a fixed capital, accounts administration, a chancery, and a dynastic necropolis later in the 12th century.

The first count born in Champagne was Henry the Liberal (r. 1152–1181), during whose rule the county emerged as a distinct political entity. Henry's greatest achievement was the creation of a territorial state from the various lands in Champagne. He built a palace in Troyes to serve as the administrative center of the new state, created a chancery, and established an accounts administration. Henry expanded the county to include borderland castles, including nine castles on the border of the Holy Roman Empire, becoming a vassal of the emperor as well. He further expanded northwards by agreement with his brother Archbishop William White Hands of Reims, while the southern border shifted when several lords transferred their primary allegiance from the bishops of Auxerre and Langres to the count of Champagne. Countess Marie continued Henry's policy. By the time of Marie's death in 1198, Champagne had become a cohesive territorial state.

Count Theobald III (r. 1198–1201), Countess Blanche (r. 1201–1222), and Count Theobald IV (r. 1222–1253) created a fairly centralized state by making the largely autonomous vassals accountable to an efficient bureaucracy and aggressively expanded the comital domain. The 13th century saw the counts more tightly control the circulation of fiefs, which passed through inheritance, grant, mortgage, sale, benefaction, and allodial conversion, and the fiefs simultaneously became open to women and non-knighted men. The War of the Succession of Champagne devastated the southeastern part of the county in 1218.

The organization of the county was based on castellanies, which became the principal administrative unit under Henry the Liberal. There were about 30 castellanies in Champagne. Each castellany was centered on a castle or a castle town and encompassed lands of the count's domain as well as those of his vassals. At its head was the viscount or castellan, who had charge over the knights who guarded the castle and the roads travelled by merchants.

The count's villages were represented by mayors, who answered to the castellany's provost. The provost held courts and collected rents, tailles, and taxes from the comital domain. The castellanies themselves were administered by the comital officials in Troyes. The count's sergeants within collected information about the fiefs and obligations of the count's fiefholders within each castellany. In the 13th century, castellanies were grouped into bailliages, which were supervised by a bailli.

The economy of the county steadily expanded through persistent land clearing and urban growth. The Champagne trade fairs, initiated under Theobald II and protected and regulated by the subsequent counts, made the county the center of international trade and finance through most of the 1100s and 1200s. They principally attracted merchants and travelers from the neighboring County of Flanders and the Rhine Valley as well as from the states of Italy and England, but they also came from as far as the Mediterranean and the Baltic.
