Prague to commemorate 10 years of Scouting. Following the end of World War I, the different associations within Czechoslovakia came together in one united national association, and the Czechoslovakian Scout and Guide Federation was among the charter members of the World Organization of the Scout Movement in 1922, with Svojsík elected to the World Committee. Before World War II, Junák had the third most members of any Scout Association in Europe, and numbered seventh in the world; by 1936 the number of Scouts in Czechoslovakia was 70,000. Junák bid to host the World Jamboree in 1933. The preparations started in earnest and in 1931 Czech Scouts prepared the "All-Slavonic Jamboree" as the test for the World Jamboree, a successful festival which culminated in a march through Prague and an address by President Masaryk at Prague castle. But in the end the World Jamboree was to take place in Hungary. Czech Scouts participated in all World Jamborees from the first in 1920 through 1937. At the 1937 World Jamboree in the Netherlands, the Junák contingent had 314 members. Antonín Benjamin Svojsík died on 17 September 1938. Czech Scouts and Guides unified on 22 January 1939 to found the new association called Junák. The Chief Scout was Rudolf Plajner and the Chief Guide was Vlasta Koseová. Junák was abolished by force and Scouting prohibited by German State Secretary Karl Hermann Frank during the Nazi occupation of Czechoslovakia on 28 October 1940. Many Scouts and Guides joined the Czech Resistance; over 700 of them died during the war as part of the movement. After the war, the association was re-registered in Prague in 1945, following the country's liberation, with 120,000 members registered in 1946, the number of members grew to nearly 250,000, (making it the second largest association in the World Movements at that time), and in 1947, a contingent of 500 represented Junák at the World Scout Jamboree in France, sporting two Scout bands. In summer 1946, Lady Olave Baden-Powell visited Czechoslovakia and she was welcomes in the whole country by Scouts and Guides. After the war, in lieu of Scout camps, their participants helped in local agriculture. Chief Guide Vlasta Koseová became the Vice-chairman of the World Committee of WAGGGS and Chairman Velen Fanderlik was a member of the World Scout Committee of WOSM. However, in 1948, after the Communist coup, Junák was disbanded; beginning in 1949, trials were held against
