There is some confusion over why Metternich was selected. Napoleon said he wanted "a Kaunitz", and whether he literally meant someone from the house of Kaunitz [de] or merely someone in the style of the Prince of Kaunitz, who had been ambassador to France from 1750 until 1753, this worked in favour of Metternich, the husband of a Kaunitz (Palmer 1972, tr. 44–47).
