The visit to the Vatican made by Kaiser William II on October 12, 1888, remains a memorable and somewhat curious event in the pontificate of Leo XIII. One version of this meeting has been given by Count Eduardo Soderini, a personal friend of Leo XIII, who thus far has been the only historian given access to the Vatican archives for this period. But the private papers of the pope's protégé and advisor, Cardinal Galimberti, particularly letters from the cardinal's German friend and informant, Monsignor Montel, suggest that Soderini's account is rather reticent and incomplete. This impression is confirmed by some documents in the papers of Friedrich von Holstein, a key figure in the German Foreign Ministry. A full account of this extraordinary meeting and a better appreciation of its significance is obtainable from unpublished documents in the French, German, and Austrian diplomatic archives, especially from a report made to Prince Bismarck by his son Herbert, a report approved and dictated in part by the kaiser himself.
