USA HISTORY

Detailed explanation-1: -There were several diseases that Europeans had built immunity to before venturing to the Americas. Diseases like smallpox, measles, typhus, and cholera quickly spread and depleted Native American populations. The disease spread quickly because Native Americans were not immune to these diseases.

Detailed explanation-2: -European colonization of North America had a devastating effect on the native population. Within a short period of time their way of life was changed forever. The changes were caused by a number of factors, including loss of land, disease, enforced laws which violated their culture and much more.

Detailed explanation-3: -Throughout the Americas, Indigenous contact with Europeans was soon followed by drastic declines in Indigenous populations. With no natural immunity to diseases introduced by the Europeans, Indigenous Peoples were decimated by waves of epidemics of smallpox, tuberculosis, scarlet fever, influenza and measles.

Detailed explanation-4: -When the Europeans arrived, carrying germs which thrived in dense, semi-urban populations, the indigenous people of the Americas were effectively doomed. They had never experienced smallpox, measles or flu before, and the viruses tore through the continent, killing an estimated 90% of Native Americans.

Detailed explanation-5: -The European colonization of the Americas was the process by which European settlers populated the regions of North, Central, South America, and the islands of the Caribbean. It is also recognized as the direct cause for the cultures of the various indigenous people of those regions being replaced and often eradicated.
