Joanna was born 24 June 1322, the daughter of John III, Duke of Brabant[1] and Marie d'Évreux.

Charles met at Maastricht with the parties concerned, including representatives of the towns, and all agreed to nullify certain terms of the Blijde Inkomst, to satisfy the Luxembourg dynasty.

[5] On Joanna's death, by agreement the Duchy passed to her great-nephew Antoine, the second son of her niece Margaret III, Countess of Flanders.

Her tomb was erected in the Carmelite church in Brussels in the late 1450s; it was paid for in 1459 by her sister's great-grandson, Philip the Good.

Though it was destroyed in the course of the French Revolutionary Wars, its appearance has been reconstructed from drawings and descriptions by Lorne Campbell,[6] who concluded that the tomb was an afterthought, providing an inexpensive piece of propaganda for Philip's dynastic rights.
