Wedding of Alfonso XIII and Princess Victoria Eugenie

The groom was the reigning king of Spain since his birth and the bride was a princess from a cadet branch of the House of Hesse-Darmstadt and a granddaughter of Queen Victoria.

The treaty was executed between Spain and the United Kingdom in London on 7 May 1906 by their respective plenipotentiaries, the Spanish Ambassador to the Court of St James's, Don Luis Polo de Bernabé, and the British Foreign Secretary, Sir Edward Grey, Bt.

These jewels, in addition to others, formed the joyas de pasar collection later, which Victoria Eugenia ensured that were successively passed on to the following Queens of Spain.

[a] Although it is impossible to determine the number of spectators at the parade, ABC estimated some 400,000 attendees, while El Imparcial highlighted that 50,000 people had arrived by train to Madrid for the event.

[1] Separately, the Princess left the Ministry of the Navy half an hour later than planned, because Prime Minister Segismundo Moret arrived late to pick her up, which worried the groom and delayed the ceremony.

[2] Immediately afterwards, the ceremony moved to a facility adjacent to the church, where the act was registered in the Registry of the Civil Status of the Royal Family [es], by Manuel García Prieto –Minister of Grace and Justice as the Chief Notary of the Kingdom–, indicating that the wedding had been communicated by the King to the Cortes and that Princess Victoria Eugenie had the permission of her uncle Edward VII.

When passing by number 88 on Calle Mayor,[b] they suffered an attack with a bomb camouflaged in a bouquet of flowers thrown from a fourth floor balcony towards their carriage by anarchist Mateo Morral with the intention of killing them.

Twenty-four people died among the members of the Royal Guard and bystanders, including the Marchioness of Tolosa and her daughter, who were watching the parade from a nearby balcony, and over a hundred others were wounded.

The King's Golden Fleece necklace broke and his uniform tore at chest level, as a piece of the bomb entered the carriage, becoming embedded in the seat.

[4] After the delay caused by the confusion, the King and the Queen changed carriages and resumed their journey to the Royal Palace, where they made several appearances on the balcony under the cheers from the crowd.
