The 45 were noblemen of lesser nobility (many from Gascony[1]) with little more than a horse, a sword, and a few acres to live on. In the king's service, they were paid a lavish wage (by their standards).[1] In return, 15 of them were to be on duty, day or night, ready at the king's call.
After the king was assassinated by Jacques Clément, the crown of France passed to Henry IV of Navarre; the forty-five also passed to him and served him faithfully until his death, which was also by assassination – ironically in a conspiracy in which Épernon may have been involved.[citation needed]
