Baden-Powell and Hungarian head of state, Regent Horthy, addressed the Scouts from the grandstand built to accommodate over 5000 guests during an opening ceremony at the rally ground.

[3] This event was notable as the first international gathering where Air Scouts were represented, including the famous pilots, László Almásy and Robert Kronfeld.

Countries and territories with contingents of Scouts present included Hungary, Scotland, Wales, Northern Ireland, the Irish Free State, England, Jamaica, Trinidad, Switzerland, Sweden, Armenia, the Netherlands, Poland, Finland, Czechoslovakia, Estonia, Australia, New Zealand, British Guiana, Canada, Newfoundland, Ceylon, South Africa, Austria, Romania, Norway, Portugal, Siam, Spain, Haiti, Greece, France, Gibraltar, India, Philippines, United States, Bulgaria, Liechtenstein, Belgium, Syria, Denmark, Iceland, Egypt, Iran, Japan, Malta, Palestine, Rhodesia, the Duchy of Luxemburg, and Russian Emigrant Scouts.

[8] The Jamboree daily paper, Magyar Cserkész, was printed in Hungarian, English, French and German, with contributions in other languages.

Every foreign group at the Jamboree was assigned a "cousin"—a Hungarian Scout who spoke their language and served as translator and guide.

Over their shirt pocket they wore an embroidered patch stating their language specialty, for example, Parle Français, Spricht Deutsch or Speaks English.

[9] During the Jamboree, about 365,000 people[8] including 100,000 from the nearby city of Gödöllő and the surrounding districts visited the Scouts from many nations, seeking "autograms"—autographs—and "change," or to trade clothing, patches, and more.

[1]Baden-Powell also referred to the symbol of the Hungarian people in his farewell address to the assembled Scouts: Each one of you wears the badge of the White Stag of Hungary.

The Hungarian hunters of old pursued the miraculous Stag, not because they expected to kill it, but because it led them on in the joy of the chase to new trails and fresh adventures, and so to capture happiness.
