During the colonial period, Native Americans had a complicated relationship with European settlers. They resisted the efforts of the Europeans to gain more of their land and control through both warfare and diplomacy. But problems arose for the Native Americans, which held them back from their goal, including new diseases, the slave trade, and the ever-growing European population in North America.
In the 17th century, as European nations scrambled to claim the already occupied land in the “New World,” some leaders formed alliances with Native American nations to fight foreign powers. Some famous alliances were formed during the French and Indian War of 1754–1763. The English allied with the Iroquois Confederacy, while the Algonquian-speaking tribes joined forces with the French and the Spanish. The English won the war, and claimed all of the land east of the Mississippi River. The English-allied Native Americans were given part of that land, which they hoped would end European expansion—but unfortunately only delayed it. Europeans continued to enter the country following the French and Indian War, and they continued their aggression against Native Americans. Another consequence of allying with Europeans was that Native Americans were often fighting neighboring tribes. This caused rifts that kept some Native American tribes from working together to stop European takeover.
Native Americans were also vulnerable during the colonial era because they had never been exposed to European diseases, like smallpox, so they didn’t have any immunity to the disease, as some Europeans did. European settlers brought these new diseases with them when they settled, and the illnesses decimated the Native Americans—by some estimates killing as much as 90 percent of their population. Though many epidemics happened prior to the colonial era in the 1500s, several large epidemics occurred in the 17th and 18th centuries among various Native American populations. With the population sick and decreasing, it became more and more difficult to mount an opposition to European expansion.
Another aspect of the colonial era that made the Native Americans vulnerable was the slave trade. As a result of the wars between the European nations, Native Americans allied with the losing side were often indentured or enslaved. There were even Native Americans shipped out of colonies like South Carolina into slavery in other places, like Canada.
These problems that arose for the Native Americans would only get worse in the 19th century, leading to greater confinement and the extermination of native people. Unfortunately, the colonial era was neither the start nor the end of the long, dark history of treatment of Native Americans by Europeans and their decedent’s throughout in the United States.

Abstract
Human impacts prior to the Industrial Revolution are not well constrained. We investigate whether the decline in global atmospheric CO2 concentration by 7–10 ppm in the late 1500s and early 1600s which globally lowered surface air temperatures by 0.15∘C, were generated by natural forcing or were a result of the large-scale depopulation of the Americas after European arrival, subsequent land use change and secondary succession. We quantitatively review the evidence for (i) the pre-Columbian population size, (ii) their per capita land use, (iii) the post-1492 population loss, (iv) the resulting carbon uptake of the abandoned anthropogenic landscapes, and then compare these to potential natural drivers of global carbon declines of 7–10 ppm. From 119 published regional population estimates we calculate a pre-1492 CE population of 60.5 million (interquartile range, IQR 44.8–78.2 million), utilizing 1.04 ha land per capita (IQR 0.98–1.11). European epidemics removed 90% (IQR 87–92%) of the indigenous population over the next century. This resulted in secondary succession of 55.8 Mha (IQR 39.0–78.4 Mha) of abandoned land, sequestering 7.4 Pg C (IQR 4.9–10.8 Pg C), equivalent to a decline in atmospheric CO2 of 3.5 ppm (IQR 2.3–5.1 ppm CO2). Accounting for carbon cycle feedbacks plus LUC outside the Americas gives a total 5 ppm CO2 additional uptake into the land surface in the 1500s compared to the 1400s, 47–67% of the atmospheric CO2 decline. Furthermore, we show that the global carbon budget of the 1500s cannot be balanced until large-scale vegetation regeneration in the Americas is included. The Great Dying of the Indigenous Peoples of the Americas resulted in a human-driven global impact on the Earth System in the two centuries prior to the Industrial Revolution.
