The exact date of the creation of the Seigneurie (lordship) d'Aspet is not known. The first lord able to be named is Ramon-At(hon) ruling there around 1068. Names of several lords who took part in the
Crusades have also been found such as Arnaud II, who left with Philippe-Auguste from
Genoa in 1190. At the beginning of the 15th century, the Coarraze family takes the lead of the territory. Raymond-Arnaud II de Coarraze fought with
Joan of Arc during the
Siege of Orléans. The last representative of the Coarraze name was dame Catherine, who supposedly commissioned the fountain we can still admire on the town's main square. She died in 1492, leaving the leadership to the
County of Foix which had
Henri III de Navarre as last baron, the soon to be king
Henri IV of France. Under his reign, Aspet and its surroundings became part of the royal territories. Thus, in the main street of Aspet (Grand-rue), which leads to the church, are to be found the remains of the Royal Judges House. ==Population==
