Mary was able to make her own choice of husband, from a number of suitors she eventually chose Archduke Maximilian of Austria, they married on the 16th August 1477, the Archduke ruled alongside her.
Sadly, only five years later Mary died aged twenty five. The Duchess had a great love of riding, whilst out hawking with her husband in the spring of 1482 she fell from her horse. The animal had tripped, it threw her and then landed on top of her, breaking her back, she died a few days later on the 27th March.
She was buried in the Church of Our Lady in Bruges.
