Death rates, Birthrates and the Balance of Power

Death rates are more than statistics — they are a driving force behind war, migration and statecraft. In Birthrates and Battlelines: How Population Shaped Global Power, Charles M. Mugera traces how mortality trends altered the fate of nations from the 18th century to the present.

Mugera combines archival research, demographic data and military history to show concrete links between population shifts and geopolitical outcomes. Readers will see how declining mortality, rising life expectancy and changing age structures reshaped labor, conscription pools and imperial strategies.

Packed with case studies — from 19th-century conscription crises to 20th-century demographic dividends — this book equips history buffs with a new lens for understanding global power dynamics.
