1st World Jamboree - 1920

  Olympia, London, England, 1920. 8,000 Scouts from 34 countries
  represented at the roll call. The location was a huge glass-roofed
  building covering six acres. The concrete floor had to be covered with
  earth for competitions. Some non-Scout participants: an alligator
  from Florida, a baby crocodile from Jamaica, a lioness cub from
  Rhodesia, monkeys from South Africa, a baby elephant, a camel.
  Baden-Powell acclaimed the Chief Scout of the World. He said, "If it
  be your will, let us go forth from here fully determined that we will
  develop, among ourselves and our boys, a commradeship through the
  worldwide spirit of the Scout brotherhood, so that we may help to
  develop peace and happiness in the world and goodwill among men."

  2nd World Jamboree - 1924

  Ermelunden, Copenhagen, Denmark, 1924. Innovations: a week's
  home hospitality for Scouts after the event; the World Scout
  Championship. Problems: too many visitors and a deluge! B-P named
  "Baden Meister" ( Danish for "bathing master"). 4,549 wet Scouts
  accommodated by the public for a night. Awards for different
  contests distributed by B-P at Copenhagen Stadium. This Jamboree
  showed that Scouting was not just a game, but that it made a
  significant contribution towards education in world citizenship.

  3rd World Jamboree - 1929

  Arrowe Park, Birkenhead, England, 1929. The coming of age Jamboree
  celebrating Scouting's 21st anniversary. 69 countries represented by
  50,000 Scouts (320,000 visitors!). B-P blew the kudu horn at the
  opening. The first Scout Promise. B-P became Lord Baden-Powell of
  Gilwell. Also the "Jamboree of Mud". A golden arrow and a hatchet
  were buried. Gilded wooden arrows were presented to national
  contingents. B-P said, "Now I send you forth to your homeland
  bearing the sign of peace, goodwill and fellowship to all your fellow
  men. From now on the symbol of peace and goodwill is a golden
  arrow. Carry that arrow on and on, so that all may know of the
  brotherhood of men."
 

  4th World Jamboree - 1933

  Gödöllö, Hungary, 1933. 25,792 Scouts in camp. The Jamboree daily
  paper was printed in Hungarian, English, French and German, with
  contributions in other languages. The unofficial language was
  "Jamboreese", which consisted mostly of signs emphasized by a happy
  smile. Each foreign contingent was provided with a "cousin", a local
  Scout who could help them with the Hungarian language. Air Scouts
  participated for the first time. First issue of commemorative Scout
  stamps. The Jamboree badge: the white stag of Hungary. "You may
  look on that white stag as the pure spirit of Scouting, springing
  forward and upward, ever leading you onward and upward, to leap
  over difficulties, to face new adventures."(B-P)

  5th World Jamboree - 1937

  Vogelensang-Bloemendaal, Netherlands, 1937. A total of 28,750
  Scouts from 54 countries. Daily displays in the arena. Girl Guides used
  the arena to welcome Lady Baden-Powell, World Chief Guide. The
  cleanest Jamboree yet: 120 showers and 650 water taps. 71 bridges
  over the canals that intersected the site. B-P was eighty years old.
  On presenting the Jamboree emblem, a Jacob staff, B-P said, "Now
  the time has come for me to say good-bye. I want you to lead happy
  lives. You know that many of us will never meet again in this world."

  6th World Jamboree - 1947

  Jamboree of Peace", Moisson, France, 1947. 24,152 Scouts were
  present. Ten years since the last Jamboree, and B-P had died in
  1941. Loudspeakers were an unpleasant innovation of the time. Indian
  Scouts celebrated their country's independence. "Challenges" were
  part of the programme. The final march, in the formation of a Carrick
  Bend (the symbol of the Jamboree). At the opening ceremony Scouts
  marched in by countries; at the closing ceremony each sub-camp
  formed the unit, and bore at its head the many flags and banners of
  the Scouts of all the countries represented in the sub-camp.

  7th World Jamboree - 1951

  Salzkammergut, Bad Ischl, Austria, 1951. 12,884 Scouts were
  present. Simplicity was the keynote of the Jamboree. Seven towers
  were erected, each recalling a previous Jamboree. As the name of
  each was announced, a flag was hoisted on one of the towers and
  the song of that Jamboree sung. It was the first time that German
  Scouts were able to take part in a World Jamboree as full members of
  the World Organization. One Scout attended from Japan. He knew no
  language other than his own and the word "Jamboree", yet he made
  the journey with no problem. The sight of Scouts waving the welcome
  flags at the airport told him that he had arrived at the right place.

  8th World Jamboree - 1955

  The Jamboree of New Horizons, Niagara on the Lake, Canada, 1955.
  The first World Jamboree and first international Scout gathering to be
  held outside of Europe. Total of 11,139 participants from 71 countries
  present. Many firsts: all cooking done over charcoal; television came
  to a World Jamboree; so did Hurricane Connie! Unusual arrivals were
  two whaling boats which were sailed up the river from Montreal
  through the Rideau Canal and across Lake Ontario; three Brazilian
  Scouts arrived by jeep; New Zealand Scouts who left home four
  months before the Jamboree started and travelled over 45,000 Km
  (30,000 miles). The greatest impact: Canadian hospitality.

  9th World Jamboree 1957

  Sutton Park, England, 1957. The Jubilee Jamboree celebrating
  Scouting's 50th anniversary. Over 30,000 Scouts from 80 countries
  were present. First to incorporate a Rover Moot and an Indaba. The
  year of B-P's centenary. An amateur radio station operated from
  camp. A Scout from Pakistan hiked all the way. There was a 24-page
  camp newspaper, "Jubilee Journal". And then, traditonally one might
  say, there was the night of the great storm - "Jamborain". An obelisk
  was erected at Sutton Park to commemorate this anniversary of
  Scouting.

  10th World Jamboree - 1959

  Mt. Makiling, Philippines, 1959. The first World Jamboree in the Far
  East. 12,203 Scouts from 44 countries present. Theme: "Building
  Tomorrow Today". Half a million visitors in one day. "The Bamboo
  Jamboree", a nipa palm and Bamboo City. The meeting of Occident
  and Orient; a revelation to both. The Filipino smile was unforgettable.
  In view of weather conditions at previous Jamborees, French Scouts,
  well prepared for all contingencies, marched past giving a splash of
  colour in yellow raincoats. A World Jamboree is not really the arena
  shows or campfires. The real Jamboree takes place in the hearts of
  Scouts from many lands.

  11th World Jamboree -1963

  Marathon, Greece, 1963. 14,000 participants. Theme: "Higher and
  Wider". The Greek Crown Prince and Chief Scout opened the

  labours of Hercules, the triathlon. Tragedy struck the Philippines'
  contingent which perished in an air crash. Jamboree flags were
  lowered in commemoration. At the closing, the Marathon torch was
  handed to an American Scout to be rekindled at the opening of the
  Twelfth World Jamboree.

  13th World Jamboree - 1971

  Asagiri Heights, Japan, 1971. 23,758 participants from 87 countries.
  Theme: "For Understanding". Many varied activities in camp made
  colourful by oriental decor set against the background of Mount Fuji.
  Perfect weather at the start and finish, but Jamboree No. 13 is
  remembered for the typhoon in the middle. Owing to the severe
  flooding of some sub-camps, 16,000 Scouts had to be evacuated for
  48 hours. Excellent emergency plans by the Japanese Scouts and
  unforgettable hospitality by temporary hosts.

  Jamboree Country Fair. H.M. the King of Norway opened the
  Jamboree, which was also visited by H.M. the King of Sweden and
  H.R.H. the Crown Prince of Morocco.

 15th World Jamboree Year - 1979

  The world is the place and the time is the whole year of 1979.
  Instead of one Jamboree, the World Organization announced the
  "World Jamboree Year" in order to multiply by thousands the spirit of a
  Jamboree by holding several World Jamboree Year camps and
  countless Join-in-Jamboree activities all over the world. The
  Join-in-Jamboree symbol represented the waves of friendship that rise
  from international gatherings of Scouts and flow around the world
  spreading the spirit of the Scout brotherhood. The Fifteenth World
  Jamboree, scheduled for 1979 in Iran, was postponed.

  Jamboree of the century. It was officially opened by Chilean President
  Eduardo Frei. 31,000 Scouts, leaders and staff from 157 countries
  and territories attended. The theme "Building Peace Together" was
  reinforced by the 3rd Global Development Village which was bigger
  and better than ever with the involvement of 11 United Nations
  agencies, and by the signing of an anti-personnel land mine
  agreement between Handicap International and World Scouting. This
  was a Jamboree that emphasized the education of Scouts about the
  world and its problems and it demonstrated how Scouts can and do
  make a difference.

  Operation Los Andes, with contributions from many contingents, made
