Premise: Margaret of Valois . Charles IX arranged for her to marry a distant cousin , King Henry III of Navarre , and she thus became Queen of Navarre in 1572 . In 1589 , after all her brothers had died leaving no sons , Margaret 's husband , the senior-most agnatic heir to France ( the `` Prince du sang '' ) , succeeded to the French throne as Henry IV , the first Bourbon King of France . Margaret took many lovers both during her marriage and after its annulment , of whom the best-known are Joseph Boniface de La Môle , Jacques de Harlay , Seigneur de Champvallon and Louis de Bussy d'Amboise . While imprisoned , she took advantage of the time to write her memoirs , which included a succession of stories relating to the disputes of her brothers Charles IX and Henry III with her husband .
Hypothesis: Margaret of Valois was married.
