Big Era 5 Key Theme 6 Science, Technology, and the Environment

The Big Five Era 

Humans and Ideas

There were a couple of major cultural developments that shaped the Big Era five, but the driving force behind it was humans and ideas. Anytime you have cultural differences it is because someone has a different idea than someone else. A major one of these ideas throughout the population was a difference in religious thinking. There were a number of different belief systems widespread including Christianity, Buddhism, and Islam. The other cultural development focused on consolidating scientific and technological traditions within complex societies and the new ideas spreading quickly across Afroeurasia.

The Big Five Era was started around 300 to 400 CE and the ancient world of Afroeurasia and its large political units came to an end. The next twelve hundred years of the Big Five Era brought lots of modern inventions and cultural changes into being. The population of the time was four million people globally thought to be linked to innovations in agriculture as well as more people from Europe to Japan being given land that they could use to grow sustenance. The larger empires of South America, West Africa and Mesoamerica came into being. Between 1000 and 1500 CE there was the emergence of the Indian Ocean focuses on long-distance commerce in Afroeurasia, and there was a universal message of comfort in allowing the religions to agree to disagree.

The Environment, War, and Black Death

The environment during the Big Five Era was changing rapidly and brought on drier conditions and declined the productivity of the farmers. Another issue this caused was plague and disease. The Black Death spread quickly through Afroeurasia taking out a considerable large percent of the population. War became a widespread mission with the fall of the Western Roman Empire and the rise of the Gupta Empire in India. In Europe the early Russian empire rose to power and the Aztec and Incan empires grew in America. War also reached new levels of violence with the use of the crossbow, and catapult among other new weapons. Despite the war economic growth was still steady from 700 to 1500. Commerce by sea was the most popular way for merchants to trade. The Big Five Area brought a lot of cultural advances and events that shaped the history of the world.

Chandragupta Maurya gained control and began conquering the surrounding kingdoms. His conquests led to the founding of India’s first empire, the Mauryan Empire, located near the Ganges River in northeastern India.The Maurya Empire was ruled by the Mauryan dynasty from 321 to 185 BC.

HUMANS AND HUMANS

Chandragupta then defeated the invasion led by Seleucus I, a Greek general from Alexander's army. Under Chandragupta and his successors, internal and external trade, agriculture and economic activities,expanded across.

The crusades brought big changes for Europe. The political system in Europe changed from feudalism to monarchy. 
The economic system went from the manorial system, where manors were self-sufficient and didn't trade, to the revival of trade throughout Europe. 
The social structure went from a structured society to a society with a new class, the middle class, and the decline of serfdom. All these changes were very big for Europe.
The political system changed in a big way in Europe after the crusades. Before the crusades, the political unit was the manor and was ruled by lords. You were loyal to the lord who owned your land. After the crusades, feudalism became weaker. The kings who led the crusades got more power. They began to form countries and impose taxes. 

There are several major Han dynasty inventions that have been famously known. These inventions have in one way or another shaped the way our world is lived in right now. The first and probably the most popular is the paper. 

It was during the Han dynasty that the cast iron processing was perfected.

Furnaces which are able to convert iron ore into pig iron and later into cast iron were operational in China during the Han dynasty period.
This helped vastly in the improvement of weapons, tools and domestic wares.
More importantly, it paved the way for the creation of new agricultural tools which in turn helped increase the agricultural tax revenue of the empire.

Also the Han dynasty, come up with the invention of silk, and they thought that could be marketed as an expensive piece of article.

Silk business created a lot of revenue for the people of the Han dynasty. The Han dynasty inventions are solid proof of the intellectual of the Han dynasty people.
