Peter had succeeded his father, John of Luxembourg, Lord of Beauvoir, and mother, Marguerite of Enghien. They had co-reigned as Count and Countess of Brienne from 1394 to her death in 1397. His name originates from the fact that he was a 6th generation descendant of Henry V, Count of Luxembourg, and thus belonged to the french branch of the House of Luxembourg.

The Black Death had hit Luxembourg, France, England and Spain in the 1340s when it caused the deaths of millions of people; and it continued to re-appear at intervals over the succeeding centuries. Peter was among its victims. He died at Rambures on 31 August 1433, aged 43 years, and was buried in the abbey at Cercamp, near Frévent. His wife died 36 years later.
