The United States Constitution is the most important document ever created in the USA and one of the half-dozen or so most important ever written by humankind. Almost all of us know that the Constitution exists. And almost all of us know a few of its key provisions. But few of us have a detailed understand and fewer still have actually read it. The Constitution is not difficult. The original document is only four pages long and is generally clear and easily understood. But with the amendments, reading it becomes more time-consuming. This book contains a brief history and description of the US Constitution and its Amendments, starting with the original document and proceeding through the Amendments, one at a time, all in chronological order. It includes un-ratified amendments and some that have been proposed but have not been approved by Congress. A discussion of the highlights of some State Constitutions is included. Technical terms are explained and a full index is provided.
