This week’s entry: Jeanne de Clisson
What it’s about: Pirates! But not just any pirate. While there were a small but significant number of female pirates, Jeanne de Clisson stood out for several reasons. For one, she was a noblewoman, born into a prominent French family and then married into two others in turn. Second, she enlisted in piracy as a widowed mother of seven, even taking two of her children to sea with her. And third, she wasn’t interested in treasure. She just wanted revenge.
Biggest controversy: As de Clisson lived in the early 1300s, many of her exploits are hearsay and there are a few gaps in her story. Historical records from both France and England, however, confirm several key facts. Her husband was executed by France as a traitor; she was convicted as a traitor by the French, and hailed as an ally by the English. The Breviary Of Belleville (de Clisson’s maiden name and hometown), an illuminated prayer book likely given to her as a wedding gift, ended up in the hands of Charles V, and survives to this day (or at least, survived long enough for a scanned image to be posted to Wikipedia).
Strangest fact: de Clisson married shockingly young, even by medieval standards. In 1312, at age 12, she married 19-year-old Geoffrey de Chȃteaubriant VIII. Jeanne gave birth to Geoffrey IX at 14, and daughter Louise two years later. Chȃteaubriant was her first of four husbands; he died in 1326. Two years later, she married Guy of Penthièvre, son of the Duke of Brittany, but the Duke’s family, worried the heir’s new bride wanted to somehow hone in on the family title, petitioned Pope John XXII to annul the marriage, which he did in 1330. Guy quickly remarried, and just as quickly died, leaving his estate to his daughter from his first marriage (presumably a son born to de Clisson would have overridden her claim).
