The core of the collection was formed by 123 paintings from the collection of Queen Christina of Sweden, which itself had a core assembled from the war booty of the sacks by Swedish troops of Munich in 1632 and Prague in 1648 during the Thirty Years War. After the French Revolution the collection was sold by Louis Philippe d'Orléans, "Philippe Égalité", and most of it acquired by an aristocratic English consortium led by Francis Egerton, 3rd Duke of Bridgewater. Much of the collection has been dispersed, but significant groups remain intact, having passed by inheritance. One such group is the Sutherland Loan or Bridgewater Loan, including sixteen works from the Orleans Collection, in the National Gallery of Scotland, and another is at Castle Howard, Yorkshire. There are twenty-five paintings formerly in the collection now in the National Gallery, London, which have arrived there by a number of different routes.
