Was the Great Dying an accident of biology or a product of policy?
For decades, historians attributed the collapse of Indigenous American populations to the arrival of Eurasian diseases. But new research suggests that pathogens like smallpox were only part of a much darker equation involving forced labor, malnutrition, and the deliberate disruption of entire civilizations.
The scale of the pre-Columbable population remains a subject of intense academic debate. While early 20th-century scholars like Kroeber suggested as few as 8.4 million inhabitants, more recent estimates place the number much higher, often between 45 and 60 million people. Some researchers, such as historian David Stannard, argue the total loss reached nearly 100 million due to a combination of 'microbial pestilence and purposeful genocide.'
The traditional narrative focuses on 'unintended' consequences: the introduction of diseases like smallpox, influenza, and measles to populations with no natural immunity. Evidence shows that in places like 16th-century Mexico, waves of disease killed between 50% and 80% of the population. However, this 'disease-only' model is increasingly contested by scholars who point to the structural violence of colonization.
Modern historians, including Jeffrey Ostler and Andrés Reséndez, argue that the impact of pathogens cannot be separated from colonial practices. They suggest that the true driver of mortality was the disruption of Native communities through forced labor—such as the encomienda system—warfare, and the destruction of trade networks. In the Caribbean, for example, the brutal conditions of slavery and forced mining were primary killers, creating the very environments of malnutrition and social stress that allowed epidemics to flourish.
This demographic collapse was so profound that some studies suggest it even contributed to the Little Ice Age by causing a drop in atmospheric CO2. While the Indigenous populations of the Americas reached a low point in the early 20th century, recent decades have seen a significant resurgence in many regions.
