Marie Louise (b.1791, d.1847), the eldest daughter of Francis I of Austria married Napoleon Buonaparte on April 1st 1810, after his desire for an heir had induced him to divorce Josephine. The marriage was unpopular with the French Nation, and indeed despite the subsequent birth of an heir, the empress apparently remained entirely indifferent to her husband. -When Paris was threatened by the advancing allies in 1814, Marie Louise withdrew to Vienna instead of retreating behind the Loire with the rest of the French court. There, she consoled herself in the absence of her husband and son by engaging in an affair with an obscure count. She never saw Napoleon again.
