Der Ring was a group of young architects, formed with the objective of promoting Modernist architecture.
With the rise of National Socialism and the increasing difficulty between Hugo Häring and the other members, Der Ring dissolved in 1933.
Six members, Bartning, Forbat, Gropius, Häring, Henning und Scharoun, were part of the project of Siemensstadt in Berlin (1929 through 1931).
The driving force behind the founding of the Ring were Hugo Häring and Ludwig Mies van der Rohe who shared an office in Berlin at the time.
Because its work didn't produce any results worth mentioning — as the Luckhardt brothers put it — they decided to extend the group in terms of geography and membership.
