The Han Dynasty (206 BC – AD 220), lasting 400 years, is commonly considered within China to be one of the greatest periods in the history of China. At its height, the Han empire extended over a vast territory of 6 million km and housed a population of approximately 55 million. During this time period, China became a military, economic, and cultural powerhouse. The empire extended its political and cultural influence over Korea, Japan, Mongolia, Vietnam, and Central Asia before it finally collapsed under a combination of domestic and external pressures.
The Han Empire was divided into areas directly controlled by the central government, known as commanderies, and a number of semi-autonomous kingdoms. These kingdoms gradually lost all vestiges of their independence, particularly following the Rebellion of the Seven States. The Xiongnu, a nomadic confederation which dominated the eastern Eurasian Steppe, defeated the Han army in battle in 200 BC. Following the defeat, a political marriage alliance was negotiated in which the Han became the de facto inferior partner. When, despite the treaty, the Xiongnu continued to raid Han borders, Emperor Wu of Han (r. 141–87 BC) launched several military campaigns against them. The ultimate Han victory in these wars eventually forced the Xiongnu to accept vassal status as Han tributaries. These campaigns expanded Han sovereignty into the Tarim Basin of Central Asia and helped establish the vast trade network known as the Silk Road, which reached as far as the Mediterranean world. Han forces managed to divide the Xiongnu into two competing nations, the Southern and Northern Xiongnu, and forced the Northern Xiongnu across the Ili River. Despite these victories, the territories north of Han's borders were quickly overrun by the nomadic Xianbei confederation. The Han Dynasty was arguably one of the strongest's empires in the world during the reign of Emperor Wu, though was established as the largest.
