Queen Victoria was on friendly terms with the family of King Louis-Philippe of France, to whom she was related by marriage: the King's daughter, Princess Louise, was the second wife of Queen Victoria's uncle, King Leopold I of the Belgians, and one of King Louis-Philippe's sons, the Duke of Nemours, married Queen Victoria's cousin, Princess Victoire of Saxe-Coburg-Gotha. The 1848 revolution in France forced the King to abdicate, and he fled with his family to England, where they lived for many years in exile. The young Prince and Princesses in the photograph are all great-grandchildren of the King.
