They also engaged in the ceramics Industry, paper making, porcelain making, tea-leaf processing, metallurgical among other activities which helped boost their economy. The people in Tang Dynasty were involved in commercial activities due to developed and improved agriculture and the handicraft industry. Inventions during the Tang dynasty were made in the fields of medicine, engineering, and sciences. Gun powder, gas cylinders and porcelain were among the few inventions during this time. Printing was another big accomplishment during this dynasty. The Song Dynasty (960–1279) of China was a period of Chinese history marked by commercial expansion, economic prosperity, and revolutionary new economic concepts.

1) Political: In Vietnam, just before the Vietnam war, the North Vietnamese wanted too unite all of Vietnam under communist rule. As the South Vietnamese government was a failure and hated by their own citizens, the Viet Cong was able to take over South Vietnam fairly easy.
2) Social: With the use of Social networks today, ISIS was able to recruit many of their soldiers. However, the challenge too this, is that the US Government had closed down many of the websites and blocked many people from leaving the country (Government challenged the ISIS in the usage of internet) (battle over the network)
3) Economic: As economies failed during the Great Depression, a German political group called the Nazi's challenged the newly created German government over the right of power. As the government failed to fix the problems, many of the germans wanted to change the government, and elected Hitler as Chancellor. Later on, Hitler became their leader.
these are so examples (yeah their bad people, i know) of how they rose to power. From these facts, we can learn how to keep history from repeating itself
hope this helps
