China

China, officially the People's Republic of China (PRC), is a sovereign state in East Asia. It is the world's most populous country, with a population of over 1.35 billion. The PRC is a one-party state governed by the Communist Party, with its seat of government in the capital city of Beijing. It exercises jurisdiction over 22 provinces; five autonomous regions; four direct-controlled municipalities (Beijing, Tianjin, Shanghai and Chongqing); two mostly self-governing special administrative regions (Hong Kong and Macau); and claims sovereignty over Taiwan.

Covering approximately 9.6 million square kilometers, China is the world's second-largest country by land area, and either the third or fourth-largest by total area, depending on the method of measurement. China's landscape is vast and diverse, ranging from forest steppes and the Gobi and Taklamakan deserts in the arid north to subtropical forests in the wetter south. The Himalaya, Karakoram, Pamir and Tian Shan mountain ranges separate China from South and Central Asia. The Yangtze and Yellow Rivers, the third- and sixth-longest in the world, run from the Tibetan Plateau to the densely populated eastern seaboard. China's coastline along the Pacific Ocean is 14,500 kilometres (9,000 mi) long, and is bounded by the Bohai, Yellow, East and South China Seas.

Han dynasty

The Han dynasty (Chinese: 漢朝; pinyin: Hàn cháo) was the second imperial dynasty of China, preceded by the Qin dynasty (221–207 BC) and succeeded by the Three Kingdoms period (220–280 AD). Spanning over four centuries, the Han period is considered a golden age in Chinese history. To this day, China's majority ethnic group refers to itself as the "Han people" and the Chinese script is referred to as "Han characters". It was founded by the rebel leader Liu Bang, known posthumously as Emperor Gaozu of Han, and briefly interrupted by the Xin dynasty (9–23 AD) of the former regent Wang Mang. This interregnum separates the Han dynasty into two periods: the Western Han or Former Han (206 BC – 9 AD) and the Eastern Han or Latter Han (25–220 AD).

The emperor was at the pinnacle of Han society. He presided over the Han government but shared power with both the nobility and appointed ministers who came largely from the scholarly gentry class. The Han Empire was divided into areas directly controlled by the central government using an innovation inherited from the Qin 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. From the reign of Emperor Wu onward, the Chinese court officially sponsored Confucianism in education and court politics, synthesized with the cosmology of later scholars such as Dong Zhongshu. This policy endured until the fall of the Qing dynasty in AD 1911.

Hexi Corridor

Hexi Corridor (Chinese: 河西走廊; pinyin: Hexi Zoulang; Wade–Giles: Ho-hsi Tsou-lang) or Gansu Corridor refers to the historical route in Gansu province of China. As part of the Northern Silk Road running northwest from the bank of the Yellow River, it was the most important route from North China to the Tarim Basin and Central Asia for traders and the military. The corridor is a string of oases along the northern edge of the Tibetan Plateau. To the south is the high and desolate Tibetan Plateau and to the north, the Gobi Desert and the grasslands of Outer Mongolia. At the west end the route splits in three, going either north of the Tian Shan or south on either side of the Tarim Basin. At the east end are mountains around Lanzhou before one reaches the Wei River valley and China proper.

History

As early as the 1st millennium BCE, silk goods began appearing in Siberia, having traveled over the Northern branch of the Silk Road, including the Hexi Corridor segment.

At the end of the Qin dynasty (221-206 BCE), the Yuezhi overcame previous settlers, the Wusun and Qiang, occupying the western Hexi Corridor. Later, Northern Xiongnu armies vanquished the Yuezhi and established dominance here during the early Han dynasty.

Silk Road

The Silk Road or Silk Route is an ancient network of trade routes that were central to cultural interaction through regions of the Asian continent connecting the West and East from China to the Mediterranean Sea.

The Silk Road derives its name from the lucrative trade in Chinese silk carried out along its length, beginning during the Han dynasty (207 BCE – 220 CE). The Central Asian sections of the trade routes were expanded around 114 BCE by the Han dynasty, largely through the missions and explorations of Chinese imperial envoy, Zhang Qian. The Chinese took great interest in the safety of their trade products and extended the Great Wall of China to ensure the protection of the trade route.

Trade on the Silk Road was a significant factor in the development of the civilizations of China, the Indian subcontinent, Persia, Europe, the Horn of Africa and Arabia, opening long-distance, political and economic relations between the civilizations. Though silk was certainly the major trade item from China, many other goods were traded, and religions, syncretic philosophies, and various technologies, as well as diseases, also travelled along the Silk Routes. In addition to economic trade, the Silk Road served as a means of carrying out cultural trade among the civilizations along its network.

Zhang Qian

Zhang Qian (Chinese: 張騫; d. 113 BC) was a Chinese official and diplomat who served as an imperial envoy to the world outside of China in the 2nd century BC, during the time of the Han dynasty. He was the first official diplomat to bring back reliable information about Central Asia to the Chinese imperial court, then under Emperor Wu of Han, and played an important pioneering role in the Chinese colonization and conquest of the region now known as Xinjiang.

Today Zhang Qian's travels are associated with the major route of transcontinental trade, the Silk Road. In essence, his missions opened up to China the many kingdoms and products of a part of the world then unknown to the Chinese. Zhang Qian's accounts of his explorations of Central Asia are detailed in the Early Han historical chronicles, Records of the Grand Historian, compiled by Sima Qian in the 1st century BC. The Central Asian sections of the Silk Road routes were expanded around 114 BC largely through the missions and explorations of Zhang Qian. Today Zhang Qian is considered a national hero and revered for the key role he played in opening China to the world of commercial trade.
