The achievements were that it managed to raise its own army and create its own currency and government. The failures were that it didn't manage to become internationally recognized, and they eventually became bankrupt. Another thing was that there was a lot of internal strife and division.

Answer: The largest American Indian tribes lived in Central and South America. Think Aztecs, Mayas, Incas, etc. In North America, the population was less dense. Even so, the city of Cahokia was built near the modern location of St. Louis, on the Mississippi River. It had many mounds and perhaps 30,000 people at its peak. In the late 1400s, the Iroquois and Algonquin groups lived in the midwest and northeast, the Cherokee lived in the southeast, the Sioux lived in the midwest, and the cliff dwellings of the southwest were already abandoned.
Explanation:
Explorers learned more about areas such as Africa and the Americas and brought that knowledge back to Europe.
Massive wealth accrued to European colonizers due to trade in goods, spices, and precious metals.
Methods of navigation and mapping improved, switching from traditional portolan charts to the world's first nautical maps.
New food, plants, and animals were exchanged between the colonies and Europe.
Indigenous people were decimated by Europeans, from a combined impact of disease, overwork, and massacres.
The work force needed to support the massive plantations in the New World, led to a 300 year slave trade that had an enormous impact on Africa.
The impact persists to this day, with many of the world's former colonies still considered the "developing" world, while colonizers are the First World countries, holding a majority of the world's wealth and annual income.
