The story of Bluebeard was one of the darker stories written by Charles Perrault (the author of the Tales of Mother Goose). Scholars have made the connection between Perrault´s work and Conomor the Cursed, a tyrant from northern France who ruled in the 3rd century. Conomor was told he was going to be killed by his future son, so he made a point to kill each of his wives before they had children. His streak was broken when he asked for the hand of Tréphine, the King of Vannes' daughter. Though they knew that he killed his other wives, they agreed because Conomor threatened to wage war on Vannes with a gigantic army. When Conomor returns from a Special Person meeting, he finds out that his wife is pregnant. Instead of being happy, like she expected, Coromer was infuriated and tried to kill her like his other wives. She ran away, gave birth to the child, but was killed later by Conomor's hounds. There are several parallels between the two stories, such as the status of the girl, Conomor killing many of his wives, Conomor going on a trip, and several others that were more specific.
A wealthy woman was asked by Bluebeard for one of her daughters' hands in marriage. The youngest one agreed and married him.
When her husband left on a trip, he told her specifically not to open the closet door. The girl, being very curious, wanted to open it anyways.
Upon opening the closet, she discovers the bodies of Bluebeard's previous wives. He finds out that she saw them, and insists that he has to kill her too.
The girl calls to her older sister, and asks her to watch for her brothers. Throughout their waiting, Bluebeard is insisting for her to come downstairs (so he could kill her).
After much longer than Bluebeard intended to be waiting, her brothers arrived. Once there, they kill Bluebeard, saving their sister.
