Title: Theobald II, Count of Champagne

Title: Theobald III, Count of Champagne
Content:  Theobald III (Thibaut; 13 May 1179 – 24 May 1201) was the count of Champagne from 1197 to his death. He was designated heir by his older brother Henry II when the latter went to the Holy Land on the Third Crusade, and succeeded him upon his death. He cooperated closely with his uncle and suzerain King Philip II of France. He died young, and was succeeded by a posthumous son, Theobald IV, while his widow, Blanche of Navarre, ruled as regent.
Title: Blanche of Navarre, Countess of Champagne
Content:  Blanche married Theobald III, Count of Champagne, on 1 July 1199 at Chartres, when she was 22-years-old and he was 20-years-old. However, Theobald III died young on 24 May 1201, leaving her pregnant. When she gave birth to a son on 30 May 1201, he immediately became Theobald IV, Count of Champagne (Theobald I of Navarre). Blanche ruled the county as regent until Theobald turned 21 years old in 1222. The regency was plagued by a number of difficulties. Blanche's brother-in-law, count Henry II had left behind a great deal of debt. Henry was the elder son but had transferred the land to his younger brother, Theobald III. Furthermore, their son Theobald IV's right to the succession of Champagne was challenged by Henry's daughter Philippa

Another major blow to morale came near the start of the invasion of 1229, when Blanche of Navarre died (of natural causes) while in retirement at Argensolles convent. Moreover, Theobald IV's second wife Agnes of Beaujeu suddenly died in 1231, leaving Theobald IV with only their five-year-old daughter, Blanche. This left Champagne in need of a male heir, prompting Theobald IV to remarry in 1232 to Margaret of Bourbon. The situation reached its nadir in 1233, when Henry II's elder daughter Queen Alice of Cyprus threatened to reprise the succession war of Theobald IV's minority yet again. Alice

Duke Theobald I's brother Matthew II, who succeeded in Lorraine, made peace and swore fealty to Blanche. Bishop William of Langres was elected archbishop of Reims in 1219, resulting in his fortuitous departure from the conflict. Erard renounced any claim on Champagne on 2 November 1221 and Philippa in April 1222. In return for renouncing his claims, Erard received a substantial cash settlement. The last rebel baron, Erard II of Chacernay, swore his renewed loyalty to Theobald IV in March 1222.
