The United States of America adopted a democratic constitution in _______.

The correct answer is B, 1787. The Constitution of the United States was drafted by the Philadelphia Convention and signed on 17 September 1787, which is why it is counted as the world's first written democratic constitution. It was ratified by the required number of states in 1788 and the new government began work in 1789. It is a short document of a preamble and seven articles, sets up a federal republic with a President elected separately from the legislature, and gained a Bill of Rights in 1791 through its first ten amendments. The makers of the Indian Constitution borrowed Fundamental Rights, judicial review, an independent judiciary, the office of Vice-President and the impeachment procedure from it. Option A is wrong because 1932 belongs to the Great Depression years. Option C is wrong because 1877 marks the end of Reconstruction after the Civil War. Option D is wrong because 2000 is more than two centuries too late. Exam tip: US Constitution signed 1787, in force 1789 — the oldest written constitution still in use.
