Napoleon did not care for Josephine's given name, Rose, so he renamed her Josephine, which she kept for the rest of her life. He proposed in January 1796 and sent her intensely romantic love letters from numerous posts around the world with the French army. Despite rumors of her infidelity and his jealous temperament, Napoleon and Josephine were crowned Emperor and Empress of the French in 1804. The couple divorced in 1810 after her infertility was confirmed, freeing Napoleon to take a wife who could provide an heir. The couple remained on good terms, with Napoleon once saying that the only thing to come between them was her debts.
