Life

Beatrice was born sometime between December 1248 and 1249, the only child of Jean I de Montfort, Count of Dreux and Jeanne, Dame de Chateaudun.

Reign

In 1249, Beatrice's father died in Cyprus, while participating in the Seventh Crusade. Thus, Beatrice succeeded her father as ruling count of Montfort at the age of about one years old.

In 1251, Jeanne married her second husband, Jean de Brienne, Grand Butler of France. Jeanne and Jean had a daughter Blanche de Brienne, Baroness Tingry (1252–1302); Blanche married William II de Fiennes, Baron of Tingry.[1] Jeanne died sometime after 1252, leaving her Beatrice and her half-sister Blanche as her co-heiresses.

Beatrice was married to Robert IV of Dreux, Count of Dreux, Braine and Montfort-l'Amaury in 1260, when she was about eleven years old. He was the son of John I of Dreux, Count of Dreux and Braine, and Marie de Bourbon. As was the custom for female rulers at this point in time, he became the co-ruler of Beatrice and Count of Montfort by right of his wife after their wedding.

Death

Beatrice died on 9 March 1312 at the age of sixty-three. She was buried in the Abbaye de Haute- Bruyère.[2]
