This book represents the first time the Constitution for the Federation of Earth has been appeared in print from an official press with its own ISBN number. The Constitution was developed by a drafting committee of 25 persons with feedback from hundreds of world citizens over a period of 33 years from 1968 to 1991. In this premiere edition, Glen T. Martin has written a substantive historical introduction situating the Earth Constitution within the world federalist movement of the past 80 years, an extensive commentary on the Constitution that explains the significance of its 19 articles one by one, and a conclusion in which he discusses the larger meaning of the Constitution and the Earth Federation Movement that promotes it. The book includes bibliography and index as well as a number of appendices containing the relevant documents surrounding the Constitution and the Earth Federation Movement.
