Alexander, duke of Bournonville (1585–1656) was a nobleman, soldier, diplomat and conspirator with estates in both the Kingdom of France and the Low Countries.
Alexander was raised as a page boy and courtier at the courts of Paris, Brussels, Vienna and Florence, but received little formal schooling and was barely able to write.
During the Bohemian Revolt he led his own regiment in imperial service, suffering combat injuries on 30 September 1620.
Returning to the Low Countries, on 12 March 1622 he was one of the pallbearers at the funeral of Archduke Albert, who had died the previous year.
[4] In March 1634, after his involvement in the conspiracy became known to the government, the Great Council of Mechelen convicted him of treason and confiscated his property.
