What events led the new nation to write the constitution?
In the Founding Period of American History, the Founders were driven to write the Constitution, and thereby re-found the United States of America on a firmer foundation, for a variety of reasons. The ongoing debate about federal power had tipped to the side of the 'Federalists,' for one thing. But also, and perhaps more importantly, the practical experience of the nation during the War for Independence had demonstrated that, without a stronger federal government, it would risk failing in its 'grand experiment' of republican self-governance.
When the US Constitution established that the entire nation was a unified or common market how was the economy affected?
Concerns among the various states of the new American nation led James Madison to propose and write the first draft of the Bill of Rights as the amendments to the not yet ratified US Constitution. Many people were concerned that the new Federal government had too much power. The Bill of Rights added to the Constitution guaranteed the basic rights of the people and of the States.
