Answer:
they were affected by diseases and war
Explanation:
The descendants of Native American arrived over soo many years ago from some parts of Asia, leading to the development of different types of cultures and societies. The Europeans began to colonize them from 1492 and the population of these indigenous Americans began to go down as a result of diseases that was inflicted on them and war waged against them. Chicken pox and measles brought from Asia had little impacts on the Europeans but killed Native Americans in numbers because they were not immune to them.
The Native Americans were fought against and removed from their lands and discriminatory policies were also put on them which rightly changed their lives.
