I want to know the answer to the following question:
When did the Greater Hamburg Act occur?
All the background I'm provided with is that "Three changes are of particular note: on January 1, 1934, Mecklenburg-Schwerin was united with the neighbouring Mecklenburg-Strelitz; and, by the Greater Hamburg Act (Groß-Hamburg-Gesetz), from April 1, 1937, the area of the city-state was extended, while Lübeck lost its independence and became part of the Prussian province of Schleswig-Holstein.". Is that enough to answer the question?
Answer: yes
