Theobald III, Count of Champagne
Theobald III of Champagne  (13 May 1179 – 24 May 1201) was Count of Champagne from 1197 to his death.
He was the younger son of Henry I, Count of Champagne and Marie, a daughter of Louis VII of France and Eleanor of Aquitaine.
He succeeded as Count of Champagne in 1197 upon the death of his older brother Henry II.
Charters were written by him and Philip II of France in September 1198 to dictate the rights of the Jews of the one "vis-
à-vis" the other and to repay debts by Philip to the count of Champagne for the employment of his Jews.
These laws were reinforced subsequently in charters that were signed between 1198 and 1231.
In 1198, Pope Innocent III called the Fourth Crusade.
There was little enthusiasm for the crusade at first, but on 28 November 1199 various nobles of France gathered at Theobald's court for a tournament (in his castle at Ecry-sur-Aisne), including the preacher Fulk of Neuilly.
There, they "took the cross", and elected Theobald their leader, but he died in 1201 and was replaced by Boniface I, Marquess of Montferrat.
Theobald married Blanche of Navarre on 1 July 1199 at Chartres.
They had two children:
As her dower, Blanche received Theobald's seven castles – Épernay, Vertus, Sézanne, Chantemerle, Pont-sur-Seine, Nogent-sur-Seine, and Méry-sur-Seine – and all the subsidiaries coming from these castles and castellaries at the Count's death.
Following Theobald's death on May 24, 1201, she was to rule as regent for the following 21 years, during which the succession was contested by Theobald's nieces, Alice and Philippa.
Theobald was buried beside his father, Henry, at the Church of Saint Stephen at Troyes.

Henry I, Count of Champagne
Henry I (December 1127 – March 16, 1181), known as the Liberal, was count of Champagne from 1152 to 1181.
He was the eldest son of Count Thibaut II of Champagne (who was also Count Thibaut IV of Blois) and his wife, Matilda of Carinthia.
Henry took part in the Second Crusade under the leadership of Louis VII of France.
He carried a letter of recommendation from Bernard of Clairvaux addressed to Manuel I Komnenos, Byzantine Emperor; he is listed among the notables present at the assembly held by Baldwin III of Jerusalem at Acre on 24 June 1148.
On his father's death, Henry chose to take Champagne, leaving the family's older holdings (including Blois, Chartres, Sancerre, and Châteaudun) to his younger brothers.
At the time this may have been surprising, for the other territories were richer and better developed.
Henry must have foreseen the economic possibilities of Champagne, and it is during his rule that the county achieved its high place as one of the richest and strongest of the French principalities.
Henry established orderly rule over the nobles of Champagne, and could fairly reliably count on the aid of some 2,000 vassals, which just by itself made him a power few in France could equal.
This order in turn made Champagne a safe place for merchants to gather, and under the count's protection the Champagne Fairs became a central part of long-distance trade and finance in medieval Europe.
In addition, the count's court in Troyes became a renowned literary center.
Walter Map was among those who found hospitality there.
The scholar Stephen of Alinerre was among Henry's courtiers, becoming chancellor of the county in 1176.
In 1179 Henry went to Jerusalem again with a party of French knights including his relatives Peter of Courtenay (brother of Louis VII) and Philip of Dreux, bishop of Beauvais.
Henry returned towards Europe by the land route across Asia Minor, and was captured and held to ransom by Kilij Arslan II, Seljuk sultan of Rüm.
The ransom was paid by the Byzantine Emperor.
Henry died on 16 March 1181.
In 1164, Henry married Marie of France, daughter of Louis VII of France and Eleanor of Aquitaine.
They had four children:
Henry built the collegiate church of Saint-Étienne in Troyes between 1157 and 1171, which he planned as a necropolis for the House of Blois.
He was buried there, as was his son Theobald III, but most of his descendants were buried elsewhere.
He died in 1181 and was succeeded by their eldest son Henry.
After Henry became king of Jerusalem, the younger son Theobald became count.
