Pre-contact Americas

 Around 15,0000-16,000 years ago, humans settled in North America.
We have theories that they came from Asia via a land bridge that connected what we know as continents. 

These people spread all the way down to Chile as early as 14,500 years ago, then around 7,000 - 8,000 years ago, they were doing agriculture, which also during that time was also around when agriculture was appearing all around the world as humans were discovering how to grow crops. 

Around 1492, Columbus arrived in America, marking the beginning of the European colonisation of America.

Most believe that the native Americans were hunter-gatherers and that America was sparsely populated by them, which is far from the truth.
The population of the Native Americans during the time of Columbus, which was around 1500 BCE, was around 50-100 million in population. 
To put the population into scale, the world population was around 500,000 during the 1500s, which means that just the population of America was roughly 10% of the world population.

Other Famous civilisations, like the Aztecs, who were from the Mexica people, are ancestors of Mexicans.
And the Mayans, who we know as one of the longest-lasting civilisations in history, and one of the civilisations to use writing via the use of hieroglyphics and made what are now Mayan Temples.

Along with the Incas, who had extravagant buildings and social structures, it is believed that it was the largest civilisation of that time.

The Mississippian people were a North American culture, which is why the Mississippi River is named after them.
And their city of Cahokia, which is now near Saint Louis, had at its peak a population of around 40,000, and this was around the same time as the Indus Valley and the ancient Chinese civilisations.

The oldest civilisation in Mesoamerica is the Olmec civilisation, which we will discuss in the next post.

Along with the Olmec, there was also the Caral civilisation, which is now in modern-day Peru.
which some people say was the "first" civilisation instead of the others.
Strangely enough, the Caral civilisation is one that we are unsure if they farmed crops, since they were a maritime culture and maybe had gotten most of their food via fishing.

We believe that the Caral civilisation developed around the 4th millennium BCE, which, to put it into scale, is around when Egypt was being unified by King Menes.

The main idea is that the Americas were already developing long before the Europeans, because some people believe that only after the Europeans came and colonised America did the American people start becoming more of a civilisation.

After the European colonisation, within 150 years or around 1650, the American population declined from 50 million - 100 million to around 6 million.
Some people say it was because of a genocide, or diseases, that the Americans couldn't recover from that were brought over by the Europeans.

These were just sampled civilisations from the Americas; there were thousands of tribes spanning both North and South America.
