The marriage of Beatrice and John was celebrated in the Château de Vincennes in December 1334, at which time she was fourteen years old.

But because the two were related in a prohibited degree, Pope Benedict XII had to give dispensation for the marriage, which was granted in Avignon on 9 January 1335.

Beatrice ceased to be queen consort following the death of her husband John at the Battle of Crécy on 26 August 1346.

Beatrice, now Dowager Queen of Bohemia, received in perpetuity the lands in the County of Hainaut, the rent of 4,000 livres and the towns of Arlon, Marville and Damvillers as her widow's estate.

In addition, when her father Duke Louis I of Bourbon died in 1342, she received the sum of 1,000 livres, which was secured from the town of Creil.

She was buried in the now-demolished church of the Couvent des Jacobins in Paris - her effigy is now in the Basilica of St Denis.
