The wedding of Prince Gustaf Adolf of Sweden, Duke of Scania, and Princess Margaret of Connaught was held on Thursday, 15 June 1905, at St George's Chapel, Windsor Castle.

The princesses were considered the most eligible and beautiful in Europe and their uncle, King Edward VII, hoped they would marry a foreign monarch or crown prince.

The Connaughts hoped to match one of their daughters with Luís Filipe, Prince Royal of Portugal, but nothing came of the trip and they continued on to Egypt.

[1] After only a few meetings, Prince Gustaf Adolf proposed at a dinner held by the Earl of Cromer, Consul-General to Egypt, on 25 February 1905 at the British Consulate and Margaret accepted.

The announcement in The London Gazette read: HIS MAJESTY was this day pleased to declare His Consent to a Contract of Matrimony between Her Royal Highness Princess Margaret Victoria Augusta Charlotte Norah of Connaught, elder daughter of Their Royal Highnesses The Duke and Duchess of Connaught and Strathearn, and His Royal Highness Prince Oscar Frederick William Olaf Gustavus Adolphus, Duke of Schonen [sic], eldest son of Their Royal Highnesses The Crown Prince and Crown Princess of Sweden and Norway, and grandson of Their Majesties The King and Queen of Sweden and Norway, which Consent His Majesty has caused to be signified under the Great Seal, and to be entered in the Books of the Privy Council.

After the service, the couple, the wedding party, and their families and guests returned to Windsor Castle where the register was signed in the White Drawing Room.

The five-foot-tall wedding cake featured figures bearing wheat, an element on the coat of arms of Sweden symbolizing the House of Vasa.

Princess Margaret wore a French-made white satin gown trimmed with orange blossom, myrtle and Irish lace.

Margaret received several jewels, including two tiaras now in the Swedish royal collection and one by Cartier which now belongs to her granddaughter Queen Anne-Marie of Greece and has been worn by almost all her female descendants on their wedding days.

Queen Sofia presented her grandson's bride with a laurel wreath necklace by Boucheron now worn as a tiara by Crown Princess Victoria.

In 1923, Gustaf Adolf, by then Crown Prince of Sweden, remarried Margaret's first cousin once removed Lady Louise Mountbatten.
