The most important and interesting phenomena from the history of the association Mathematische Kränzchen in Prag (the Prague German Mathematics Community), which operated in Prague between spring 1913 and spring 1934, will be introduced, on the basis of the study of surviving archive sources available in Czech country and abroad, original professional journals mathematical works, and diverse secondary literature. We will try to clarify the position of the German mathematical community in the Czech lands, respectively in Central Europe in the 1920s and 1930s. We will try to capture its specifics resulting from the Prague genius loci, to describe its contributions to the development of science, to indicate its links to the surrounding German scientific world and to show its relations with Czech and foreign professional associations and societies.
