German republic until 1933 (6)
I believe the answer is:
weimar
'german republic until 1933' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for weimar that I've seen before include "German city associated with Liszt and Goethe" , "German republic until 1933" , "City of Germany" , "German town giving its name to 1919-33 republic" , "German town associated with Goethe, Liszt and Schiller" .)
