Peter was the 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.

He succeeded his father and his aunt Jeanne of Luxembourg, Countess of Saint-Pol and Ligny, as Count of Saint-Pol in 1430.

Peter married Margaret de Baux (a descendant of the Baron of Lisarea Gilbert d'Escors, daughter of Francesco del Balzo's third wife Sueva Orsini, a relation of Clarice Orsini (wife of Lorenzo de' Medici). Peter and Margaret had nine children including:

Louis of Luxembourg, Count of Saint-Pol, de Brienne, de Ligny, and Conversano, Constable of France (1418-19 December 1475), married firstly, in 1435, Jeanne de Bar, Countess of Marle and Soissons (1415-14 May 1462), by whom he had issue, and from whom descended King Henry IV of France and Mary, Queen of Scots. He married secondly, Marie of Savoy (20 March 1448-1475), by whom he had further issue. He was beheaded in Paris in 1475 for treason against King Louis XI.

Jacquetta of Luxembourg (1415/1416-30 May 1472), married firstly in 1433, John, Duke of Bedford, and secondly, in secret, c.1436, Richard Woodville, 1st Earl Rivers, by whom she had sixteen children, including Elizabeth Woodville, Queen consort of King Edward IV of England. Every English monarch after 1509 descended from her.

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.
