Nicholas I of Russia
Issue

Nicholas I had seven legitimate children with his wife, Alexandra Feodorovna.

Many sources state that Nicholas did not have an extramarital affair until after 25 years of marriage, in 1842, when the Empress's doctors prohibited her from having sexual intercourse, due to her poor health and recurring heart attacks. Many facts dispute this claim. Nicholas fathered three known children with mistresses prior to 1842, including one with his most famous and well documented mistress, Varvara Nelidova.
