Surprisingly, there are native tribes around the world who are still living a pre-contact life. Many of the following tribes have resisted contact and resorted to violence to protect themselves. It probably is for the best since many native tribes have faced extinction upon contact due to disease.
Diseases such as Tuberculosis and Smallpox, wars with Europeans and interactions with whites led to the decimation and extinction of many native tribes. Various tribes amalgamated with other tribes, while others became extinct with time.
