As our society confronts climate change, authoritarianism, and epidemics, what can examples from the past tell us about our present and future? Historical Systemic Collapse offers case studies of societies that either collapsed or overcame cataclysmic adversity. The authors of this volume find commonalities between past civilizations and our current society, tracing patterns, strategies, and early warning signs that can inform decision making today. While today's complex world presents unique challenges, many mechanisms, dynamics, and fundamental challenges to the foundations of civilization have been seen throughout history - highlighting essential lessons for the future.
