Louis was the fourth son of Walter III of Enghien and Isabella of Brienne. When his mother divided the inheritance of his uncle Walter VI of Brienne among her sons, he received the title of Count of Conversano. In 1370, he and his brothers, including John of Enghien, wrote to the Doge of Venice to request Venetian aid in reclaiming Athens from the Catalan Company, but help was not forthcoming. On the death of his childless nephew Walter V of Enghien in 1381, he also became titular Duke of Athens, Count of Brienne and Lord of Enghien.

He married Giovanna of Sanseverino, and they had four daughters: Margaret, Yolanda, Isabella, and Helena. On his death, at Conversano, on March 17, 1394, his titles were inherited by his eldest daughter

• Margaret (born 1365). In 1380, Margaret married John of Luxembourg, Lord of Beauvoir (1370–1397), son of Guy of Luxembourg and Mahaut of Châtillon, by whom she had issue, including
  • Peter I of Luxembourg, Count of St. Pol, of Brienne and of Conversano, and
  • John II of Luxembourg, Count of Ligny.

Peter I married in his own turn, Margaret de Baux, by whom he had nine children: among them are Louis, Count of St. Pol, Brienne, and Conversano, and Jacquetta (mother of Queen consort Elizabeth Woodville).
