# Counts and viscounts of Châteaudun

The County of Châteaudun was held in the 9th century by counts who also held the County of Blois. Theobald I created the first viscount of Châteaudun with the appointment of Geoffrey I, founder of the House of Châteaudun. The viscounts were entrusted with the government of the county of Châteaudun, records of whom are continuous from the mid-10th century. The actual rule of Châteaudun between the late 9th and the mid-10th centuries, and the relationships between the count and viscounts, is uncertain. The county was revived in 1439 when the region was recreated as the County of Dunois and granted to Jean Levieux Valois des Orléans (Jean de Dunois), the illegitimate son of Louis I, Duke of Orléans, son of Charles V of France.
Châteaudun is closely associated with the County of Perche and the early rulers generally held both titles of viscount of Châteaudun and count of Perche. There are also close ties between these counts and the counts of Anjou, and members of the House of Ingelger and House of Plantagenet descended from this line. The family tree of the House of Châteaudun is most illustrative of these relationships. The following lineage shows the counts of Châteaudun, the viscounts of Châteaudun, and the related counts of Perche and Anjou. Dates shown are the approximate dates of rule.
