1870s. King Amadeo I of Spain and queen María Victoria.
"The wedding day of Prince Amedeo and Donna Maria Vittoria was marred by the following tragic events:
To begin with, the bride’s wardrobe mistress hanged herself instead of the bridal gown: a thoughtless act which necessitated the finding of another gown for the superstitious Princess. The colonel who was to lead the procession from the palace to the church fell from his horse with sunstroke, causing delay until a new officer arrived. The third contretemps was the failure of the palace gates to open. The gatekeeper was found dead in a large pool of blood, and a substitute had to be recruited to open the gates.
The ceremony itself was not spoiled by anyone’s dying, but shortly afterward the best man contributed to the excitement by firing a pistol at his head. The procession proceeded toward the railway station, where the bridal party was to entrain, when suddenly the official who had drawn up the marriage contract succumbed to an apoplectic fit. At the station, the overzealous stationmaster fell beneath the wheels of the approaching bridal train, whereupon the King, thoroughly frightened, refused to allow anyone to board the train. Instead, the party returned to the carriages to drive back to the palace. The Count of Castiglione trotted alongside the bridal carriage, when suddenly he either fell or was thrown from his horse. The carriage wheels passed over him, crushing his new Order of the Annonciade into his chest and wounding him beyond hope. The House of Savoy considered the day an unhappy omen for the dynasty, and die whole affair was hushed up. “
