Hélie IX of Périgord

Hélie IX (c. 1261–1311) was Count of Périgord from 1294, son of Archambaud III. In 1276 he married Philippa, heiress of her brother Vézian III, Viscount of Lomagne and Auvillars; after Vézian's death in 1280 Mathe de Bordeaux disputed the claim before the English duke of Aquitaine, though he kept Lomagne until Philippa's death in 1286.

He married Brunissende of Foix in 1298. In 1301 he ceded both lands to Philip IV of France to keep them from English sway. He died in 1311, leaving Archambaud IV a minor under Brunissende's regency.
