Elias V Rudel of Périgord

Hélie V, called Rudel (c. 1083–1149), the younger son of Hélie III, ruled Périgord from 1115, after years beside his brother Guillaume III and their uncle Adalbert III. His bitter war against Adémar le Barbu of Limoges cost the lives of his own sons.

Left without an heir, he made his nephew Boson IV co-ruler, and by 1149 Boson governed alone. Hélie last appears in a charter of 1146; his nickname Rudel meant the hard or cruel one.
