Conclusion

Humans migrated to the Americas by 15,000 BCE and perhaps as many as 3,000 years before. The earliest recognizable civilizations in the Americas were in Mesoamerica and began during the Archaic period, ten thousand years ago. Farmers in Mesoamerica began to cultivate crops such as corn, squash, beans, chilies, manioc, and sweet potatoes. During Mesoamerica’s more recent Formative Period, the rise of the Olmec Civilization occurred. They would be followed by several others, most notably the Maya, and further to the north the Aztec Empire that was at its height when the Spanish arrived in 1519.

Around 3,000 BCE, small campsites and fishing villages began to appear in Peru. These were eventually replaced by more permanent structures and agriculture communities which would be the antecedents to the incredibly complex cultures of the Classical Andes in Peru, Chile, Ecuador, Bolivia, and Colombia. Among these Pacific Coast cultures were the Moche, the Huari, the Chimu, and the Nazca. Many of these cultures had their political and cultural centers in large urban areas like Tiwanaku, which had a population of about 40,000 people around 100 CE. More than 1,000 years later, it was the Inca Empire that would build on these cultural traditions, extending its rule over more than 5,000 kilometers from Ecuador to Chile.

Sedentary culture first began in North America when people in the desert southwest of the continent began to cultivate maize about three thousand years ago. Groups like the Chaco Anasazi in New Mexico would eventually construct massive complexes of aqueducts, homes, and ceremonial spaces by about 1000 CE. There were other major cultural areas all over North America, from Florida to the frigid Arctic.

Despite (or perhaps because of) their late arrival in the Americas, humans developed at an incredible pace all across the region. The residents of the Americas developed remarkable political sophistication, infrastructure, religion, art, economic integration, and technology that Europeans marveled at when they arrived in the late fifteenth century.
