Where Europeans went in North America, they brought disease that wiped out an estimated 75% of the Native American population. They brought wholesale murder with their muskets. They insisted on dependency for the Native American survivors, a small and battered group.
Got a reliable
documented source for that number?
You lead the way. It sounds like you know how to get there.
Many reliable sources have reported similar or higher numbers; I've also heard 80%.
The Story Of... Smallpox – and other Deadly Eurasian Germs
Much of the credit for European military success in the New World can be handed to the superiority of their weapons, their literary heritage, even the fact they had unique load-bearing mammals, like horses. These factors combined, gave the conquistadors a massive advantage over the sophisticated civilisations of the Aztec and Inca empires.
But weapons alone can't account for the breathtaking speed with which the indigenous population of the New World were completely wiped out.
Within just a few generations, the continents of the Americas were virtually emptied of their native inhabitants – some academics estimate that approximately 20 million people may have died in the years following the European invasion – up to 95% of the population of the Americas.
No medieval force, no matter how bloodthirsty, could have achieved such enormous levels of genocide. Instead, Europeans were aided by a deadly secret weapon they weren't even aware they were carrying:
Smallpox.
