His father, Hugh IX de Lusignan was betrothed to marry 12-year-old Isabel of Angoulême in 1200, when King John of England took her for his Queen, an action which resulted in the entire de Lusignan family rebelling against the English king.

By Hugh's marriage to Isabella, he became Count of Angoulême until her death in 1246. Together they founded the abbey of Valence. They had nine children:

Hugh X was succeeded by his eldest son, Hugh XI of Lusignan.

He was buried at Angoulême.
