Q. Which country's constitution was the "Weimar Constitution"?
Answer: Germany
Notes: The Constitution of the German Reich, usually known as the Weimar Constitution, was the constitution that governed Germany during the Weimar Republic era (1919–1933). The constitution declared Germany to be a democratic parliamentary republic with a legislature elected under proportional representation. Universal suffrage was established, with a minimum voting age of 20. The constitution technically remained in effect throughout the Nazi era from 1933 to 1945, though practically it went unenforced. The constitution's title was the same as the Constitution of the German Empire that preceded it.
