Napoleon himself called him ‘the most beautiful prince of Europe’ long before he became the first King of Belgium. Leopold 1 was a BAMF, and his love life reads like a (sad) romance novel.
Women all over Europe loved him ( Among them Catherine the Great, who adored him and made him first a colonel and later a general of the Russian army) but the love of his life was the crown princess Charlotte of England. They were wed and moved into Claremont House near Windsor. Their marriage was a happy one but sadly short-lived; Charlotte died giving birth to their first child, a stillborn son. Leopold would never truly get over her death.
He refused the crown of Greece but after some reluctance accepted the crown of Belgium. He married Louise of Orléans, daughter of the king of France. It was a political marriage, mostly because the age difference (22 years) was so significant; Louise had always known him as an uncle before they were engaged to be wed. Nevertheless, he was kind to her during those first years of marriage and they had four children together, one of them a daughter whom Leopold named Charlotte after the love of his life. After the children were born, though, he left Louise alone more often and for longer periods of time. It is said that even as he got older, he remained handsome and had countless mistresses, including a famous actress and a woman whom he knew for over twenty years and had two sons by.
Leopold is pretty awesome
