2. Many indigenous people were killed by the settlers, as they where no match for the guns and horses that the Europeans brought.
3. Many natives where forced into slavery and terrible living conditions, causing further death.
4. In some cases, the European conquers turned the indigenous tribes against each other, inciting further violence.
5. The displacement of Native Americans by settlers as they pushed further and further into the continent also resulted in a decline in the population.
