I want to know the answer to the following question:
Until 1933 how many configurations in the German states occurred?
All the background I'm provided with is that "In fact, until 1933 there were only four changes in the configuration of the German states: The 7 Thuringian states were merged in 1920, whereby Coburg opted for Bavaria, Pyrmont joined Prussia in 1922, and Waldeck did so in 1929.". Is that enough to answer the question?
Answer: yes
