The expression Weimar Republic is a nickname which only came into use after the republic had collapsed. If you look at stamps issued in 1919-32 you'll find that they say Deutsches Reich. This was a concession to hardline conservatives, who had an absolute horror of the word republic. The republic created in 1918-19 was not in fact 'based on Weimar'. The point is that the National Assembly met in Weimar in 1919 in order to work out a new constitution in peaceful surroundings, away from Berlin.
