Final answer:
The Period of Division followed the end of the Early Han dynasty, which was known for its establishment of a strong bureaucratic system and promotion of Confucianism. so, option c is the correct answer.
Step-by-step explanation:
The period of disunity, often referred to as the Period of Division, followed the end of the Early Han dynasty, not the Qin or Later Han. The Han dynasty is known for its stability and development of a solid bureaucratic system, which was further strengthened by the promotion of Confucianism. Upon its collapse in 220 CE, a turbulent era ensued, known as the Period of Division or Wei-Jin and Northern and Southern Dynasties, lasting until 589 CE. This period was characterized by frequent warfare, shifting alliances, and numerous short-lived dynasties. It was ultimately concluded with the reunification under the Sui dynasty.
The Period of Disunion (Division) followed a peaceful and stable period at the end of the Early Han dynasty. The Early Han dynasty lasted for over four hundred years and saw the consolidation and development of imperial institutions, as well as the expansion of trade and the establishment of caravan routes connecting China with Central Asia and India. However, after the fall of the Early Han dynasty, China experienced a period of division and fragmentation, with various dynasties and would-be dynasties ruling only small areas of China. The political unity that characterized the Early Han dynasty was not the norm during the Period of Disunion.
