American Histrology is the result of more than twenty years of research by Ron Howland, the author. Beginning with an historical overview of July 4, 1776 and the U.S. Declaration of Independence, he presents a possible birth time for the United States. Part II examines the link between the late mutable degrees and historic U.S. events, including the chart for Great Britain, the country's economics, the use of Agent Orange, and 911 and what the author calls the "missing charts." Part III is a chronology of charts from 1066 to 2011, Part IV is a chronology of presidential birth and inauguration charts from 1776 to 2013, Part V traces the history of powered flight with a chronology of charts, and Part VI does the same with nuclear energy. Each of the more than 600 charts in the chronology sections is accompanied by a description of the event, resulting in a concise yet thorough history of the United States that is especially invaluable to those interested in mundane astrology.
