What was important about the Constitution of 1787?

Answer 1

It replaced the American government under the "Articles of Confederation" to a better one under the "Constitution". Under the earlier government which was a "confederation" each state was like a separate country. This is why they were called "states. The central government had little or no power. Congress couldn't raise money. They couldn't force the states to do anything. Some states actually fought battles. So they met in Philadelphia "in order to form a more perfect union". They drafted the "Constitution" to replace the "Articles of Confederation". The United States became a "federation" or "federal republic". Power was now vested in the central government. It provided for a "chief executive" or president. It formed a system of "checks and balances" between the executive branch (the president), the legislative branch (the Congress) and the judicial branch (the Supreme Court). It also was a compromise between the large states and the small states by having two houses of Congress. In the Senate each state had two senators. This favored the small states. In the House of Representatives the larger states had more representatives because it was based on population.

Um... you mean other than the fact that it created the independent country of the United States of America and officially created the basis for all its government?
