This book examines the cyclic movement of the planets and how these cycles impact history. Three of the slowest moving planets - Saturn, Uranus, and Pluto - are in unusual relationships with each other, beginning in the early 2000s and peaking with the global economic uncertainties beginning in 2008 and the dramatic shifts in political life in the Arab world in 2011. This energy continues from 2012 through 2016. This book unravels the underlying meanings of these changes. It presents original research that shows how the these planetary cycles relate to armed conflicts between nations, civil unrest within a nation, major changes in governance, and economic downturn cycles in the United States. Starting with a database of thousands of historical events from 1200 CE to the present, it presents detailed evidence for the impact of the planetary cycles on these events. The results from this research confirm a profound link between planetary cycles and human events. This is a systematic, data-driven approach to planetary cycles and mundane astrology.
