Final answer:
The Tlingit Indigenous group suffered widespread death from smallpox after contact with Europeans.
Step-by-step explanation:
The Indigenous group that suffered widespread death from smallpox after contact with Europeans was the Tlingit tribe.
When European explorers and settlers came into contact with Indigenous peoples in the Americas, they brought with them various diseases, including smallpox. The lack of immunity among Indigenous populations led to devastating outbreaks of smallpox, resulting in widespread death and population decline.
For example, in the late fifteenth and early sixteenth centuries, diseases such as smallpox caused a drastic decrease in the Native American population, with estimates ranging from millions to hundreds of thousands of lives lost.
