At the first nationwide youth meeting in 1950 at the Wuhlheide in East Berlin, a park was opened known as the "Pionierrepublik „Ernst Thälmann“" ("Ernst Thälmann Pioneers' Republic"), later changed to "pioneers' park". About 20,000 children stayed there for the meeting. A headquarters for the young pioneers was opened in Berlin at the same time.
