Incas

They had guns and horses the natives didn't which were a powerful advantage. The took advantage of their hospitality and then betrayed them. They killed their leaders. The Europeans carried diseases the natives weren't immune to that killed staggering numbers.

The Spanish were experienced horse riders, musketeers and cannoneers. They also carried many diseases that the Indians were not immune to.

The Spanish took advantage of both empires hospitality. and along with their superior firepower and European diseases, conquered the two great civilizations.

The fall of the Incas started with the kidnapping, ransom and murder of Chief Atahualpa.

The fall of the Aztecs began with the misbelief that Hernando Cortes was Quetzalcoatl, an Aztec god. Moctezuma II soon saw he was not and offered him gold and gifts to urge him to turn back. This only encouraged Cortes to continue his mission. Upon entering the city of Tenochtitlan, Cortes kidnapped Moctezuma II and murdered him in the house they had graciously given to him.

Inca Government

The Inca empire was like a pyramid with the Sapa Inca at the top. The empire was divided into 4 regions ruled by men called opas. Below them there were more layers of government.

To help rule their vast empire the Incas created an efficient network of roads. The Incas also made rope suspension bridges. As well as the roads the Incas had messengers called chasquis. Messages were carried by relay. Groups of messengers lived in houses by main roads and at all times two of them kept lookout. If they saw another messenger approaching one of them would run to meet him. The two messengers would run together for a while and the message was passed on from one man to the other. Using this relay system messages could be sent over long distances very quickly. Inca messengers could take messages 240 kilometres in one day.

Furthermore although they never invented writing the Incas kept records with a device called a quipu. It was a cord with strings of different thickness and colours hanging from it. Knots were tied at different positions in the strings. The colour and thickness of the strings and the positions of the knots all meant something.

The Incas did not have prisons. Instead for serious crimes such as murder, stealing and blasphemy offenders were executed by being pushed off a cliff. Less serious crimes were punished by cutting off the hands or blinding.

They realized that the Inca empire was the city of gold. The Spanish became poor during this time so some Spanish people set sail and brought back stories about the city of gold. So Francisco Pizarro set sail to Peru and found the city of gold (Inca empire). He then treated them like slaves and made them change religion to Christianity.

Yes they knew of the wheel, but no carts or barrels.

3. Allies

1438-1532 a.d it impacted the people by not living and not having a civilization anymore

I didn't really understand your question but I think you mean the order of which they came in. First came the Maya, then the Aztec, and then the Inca :)

Of course that was the order of their creation. There was a period where their empires existed simultaneously.

200 Spanish conquistadors came and ambushed the Inca ruler. in the process they killed millions of Incas without loosing one of there own. Over the years the remaining Incas tried to regain there city but all attempts failed.

Aztec

The Aztec civilization was a large empire with a very centralized form of government and a very distinctive capital city (Tenochtitlan), while the Maya civilization was composed of a series of city-states with no centralized government.

A Chosen Women is first separated from her family and taken to train in a convent or temple. For four years, she is trained in religion, weaving, and how to run a house. In these years, some are sacrificed and this was thought to be an honor. A Chosen Women's main role is to weave cloths that were used for the emperor's clothes. They also created foods and drinks for religious ceremonies. They could also end up becoming a concubine of the emperor or a wife of a noble.

a variety of environmental existed throughout this region.

Since memories began the native peoples of this country fought each other. They formed alliances and dissolved them as the need arose. A great deal of the fighting was over territory encroachment or the need to hone their skills. With few exceptions, the Indians did not recognize the need to join together to fight the European Invaders since the natives were much superior warriors. Also tribal customs, legends and lifestyles were too different to form lasting alliances.

I know the Inca did not have a writing system, but they did have a speaking language/system. I do not know about the Mayas and the Aztecs. I am researching them.

Francisco Pizarro was the Spanish conquistador that conquered the Incas.

Francisco Pizarro was the Spanish Conquistador who overthrew the Inca Empire. The Spanish conquest of Inca Empire was an important campaign in the Spanish colonization of the Americas.
Spanish soldiers, under the command of Francisco Pizarro, conquered the Incas after a victories battle, known as the Battle of Cajamarca in 1532. After decades, the fighting ended in Spanish victory and the conquest of the Inca Empire.

These roads provided easy, reliable and quick routes for the Empire's civilian and military communications, personnel movement, and logistical support. The prime users were imperial soldiers, porters and llama caravans, along with the nobility and individuals on official duty. Permission was required before others could walk along the roads, and tolls were charged at some bridges.

Although the Incan roads varied greatly in scale, construction, and appearance, for the most part they varied between about 1 to 4 meters (3.3 to 13 ft) in width.

Much of the system was the result of the Incas claiming exclusive right over numerous traditional routes, some of which had been constructed centuries earlier mostly by the Wari Empires. Many new sections were built or upgraded substantially: through Chile's Atacama desert, and along the western margin of Lake Titicaca, serve as two examples. The Incas developed techniques to overcome the difficult territory of the Andes. On steep slopes they built stone steps resembling giant flights of stairs. In desert areas near the coast they built low walls to keep the sand from drifting over the road.

Both were governed by Emperors Both governed a vast number of states (that covered a huge geographical area) dominated by a central state. Both were unified as an empire but displayed cultural and ethnic diversity

There were never any Incas in Mexico, as they were a people from South America.

The Aztecs were utterly destroyed, while several Mayan peoples still live in the southeastern states of Mexico, as well as Belize, Guatemala and el Salvador.

i pretty sure the roman empire was 5.7 kilometer

Pizarro was able to conquer the Incas for many of the same reasons Cortes was able to conguer the aztecs. He had a very small, but militarily advanced army which was foreign and frightful too the Incas. In addition, the Europeans brought over those great diseases like small pox (also known as cow pox).

The Aztec and Maya civilizations traded extensively; in addition, some Aztec warriors lived at least semi-permanently among the Maya, because their presence is documented at the time of the Spanish arrival in Mesoamerica. Interaction between Mesoamerican civilizations and the Inca is less obvious, but there had to have been at least some since smallpox decimated the Inca before the Spanish themselves conquered the empire, showing that smallpox was transmitted from the Maya and/or Aztecs to the Inca before direct European contact.

Aztecs and Mayans had pyramids, whereas Incas did not. Also Mayan pyramids where taller and skinny when Aztec pyramids are shorter and flatter.

The Olmecs were a people from the tropical south-central lowlands of Mexico and their culture only really thrived from (aproximately) 1200 BCE to 400 BCE, when they slowly died out.

The Aztec empire was officially conquered by the Spanish in 1521.

The Inca civilization ended with the capture and execution of their last ruler in 1572.

The Mayans didn't have a 'political center' to conquer as a means of getting the whole. But the last Mayan states finally surrendered to the Spanish in 1697.
