Peter I of Luxembourg

Peter of Luxembourg (1390 – 31 August 1433) was a son of John of Luxembourg, Lord of Beauvoir, and his wife Marguerite of Enghien. His inheritance included the counties of Brienne, Conversano and Saint-Pol.

Family

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.

John was a fourth-generation descendant of Waleran I of Luxembourg, Lord of Ligny, second son of Henry V of Luxembourg and Margaret of Bar. This cadet line of the House of Luxembourg reigned in Ligny-en-Barrois. This made Peter a distant cousin to John of Luxembourg, father of Charles IV, Holy Roman Emperor, and Bonne, Duchess of Normandy and Aquitaine.

Peter was a sixth-generation descendant of John II, Duke of Brittany, and his wife Beatrice of England, through their daughter, Marie.^[1]

Beatrice was a daughter of Henry III of England and his wife Eleanor of Provence.

Henry was son of John of England and his second wife Isabella of Angoulême.

Life

Peter succeeded his aunt Jeanne of Luxembourg, Countess of Saint-Pol and Ligny, as Count of Saint-Pol in 1430. His younger brother John II of Luxembourg, Count of Ligny, an ally of the English during the Hundred Years War, received Joan of Arc as his prisoner, and subsequently sold her to the English, for 10,000 livres.

On 8 May 1405, Peter married Margaret de Baux (a descendant of the Baron of Lisarea Gilbert d'Escors<ref name "text=1">L'Achaïe féodale: étude sur le moyen âge en Grèce (1205-1456).

Death

The 14th and 15th centuries were well known for the Black Death, a deadly form of bubonic plague that eventually spread across the known world. Europe was badly hit by the pestilence, as a result of trading with countries with the plague; it soon grew to epidemic proportions, and would kill swiftly, and without discrimination as to gender, age or class. The plague 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.^[5] His wife died 36 years later.
