14 March 1928: King George and Queen Mary welcome King Amanullah and Queen Souriya of Afghanistan
King Amanullah and Queen Souriya of Afghanistan arrived in England yesterday. They were escorted into Dover by destroyers and aeroplanes, and met by the Prince of Wales. In London King George and Queen Mary were waiting for them, and drove with them to Buckingham Palace through cheering crowds.
Later in the day the royal visitors drove to the Cenotaph, where they placed a wreath, and then to Westminster Abbey, where another one was placed on the Unknown Warrior’s grave. In the evening they received addresses of welcome from the London County and Westminster City Councils at St James’s Palace, and at night a state banquet was given in their honour at Buckingham Palace.
