… Napoleon married Josephine with specific intent to get an heir. Josephine was the widow of a French General, & came to the marriage with 2 children. She never gave Napoleon his own heir, so he divorced her. Her daughter, Hortense, would carry on the Bonaparte line.
Reigning houses of Sweden, Denmark, Belgium, Norway, & Luxembourg came from Josephine’s children.
