Early Empires
Rome
One of the key advances of the Roman Empire was its system of government which included civil service. Civil Service was when the governor paid workers to manage the government affairs, this was a much better system than having slaves although they did have some still. Along with this efficient system of government, the Roman Empire had a good agriculture system as well as a vast trading system. Their complex network of roads also advanced them in many areas.


Greece
Greece developed what is arguably the greatest contribution to civilization from
the ancient world, democracy. The word democracy derives from the Greek ‘dēmos’, which applies to the common people. The political systems originates from Athens who thought that the best way to advance as a society was if everyone had a voice. Though women and slaves could not vote, ancient Greeks experienced little political spats and created a foundation for future societies such as our own. Additionally, trade rewarded Greece with territorial expansion. Located around the Mediterranean, Greeks were easily able to ship wine, olives and pottery which spread Greek culture around the world.

Persia
Persia’s main skills were that of military achievement, as they had one of the largest armies of the time. The Persians also had a huge trade system, comprised of many roads. These trade roads were used to transport goods and to trade with other civilizations, and could take as long as 2 months to travel.
Skills and Powers
The skills and powers of an empire advance it both socially and economically. It is essential that empires obtain skill and power in order to gain control of neighboring states and expand their land further. Power is necessary in the creation of empires because it enables the ability of influencing customs, religion and the overthrowing of other governments. Skills is the ladder between power and weakness. Without skills on the battlefield or in the mind, empires are not capable of advancement.

China
After the Zhou Dynasty, leading up to the Qin Dynasty and later the Han, there were many different ethical systems that were proposed and used. Confucianism was based upon relationships that relied the respect of elders and ancestors, established by the scholar Confucius. Another ethical system was the Legalist system, which decided that a strong government could improve society. These influential systems were able to vastly improve society, displaying the skills of the ancient chinese. During the Qin Dynasty, Qin Shuangdi was a powerful emperor that expanded his kingdom and defeated his many enemies through the incredible army that he controlled. The ancient chinese army and their methods was one of the most important skills and powers of the ancient world. In the Han Dynasty, Liu Bang established a centralized imperial government, similar to the Qin Dynasty. Unlike previous rulers, Liu Bang established a structured society and government that allowed the interactions between royals and commoners to be pleasant. This healthy integration and understanding gave the ancient chinese a huge advantage over other settlement, which they were able to conquer easily. This relationship proved to be another one of the important powers of the Han.

India
Religion is a really important skill. Also, caste system is one of the way Mauryan empire use. Indian believe that god will reward their loyal human servants with large harvests and abundant herds. Because there is a big different between the life of upper level(Brahmin, Kshatriya, vaisya) and lower level(Sudra, untouchable). Brahmin enjoy exemption from taxation, and get generous gift from services. The huge different between different level makes people in lower level want to move to upper level and it will make society unstable. The ruler use religion to make people believe that even they don’t have anything now, but if they work hard and always being loyal, they will earn things after they died.
