Chu (state) in the context of "Emperor Yi of Chu"

Qin Shi Huang (Chinese: 秦始皇, Qín Shǐ Huáng, pronunciation; February 259 – 12 July 210 BC) was the founder of the Qin dynasty and the first emperor of China. Rather than maintain the title of "king" (wáng 王) borne by the previous Shang and Zhou rulers, he assumed the invented title of "emperor" (huángdì 皇帝), which would see continuous use by monarchs in China for the next two millennia.

Born in Handan, the capital of Zhao, as Ying Zheng (嬴政) or Zhao Zheng (趙政), his parents were King Zhuangxiang of Qin and Lady Zhao. The wealthy merchant Lü Buwei assisted him in succeeding his father as the king of Qin, after which he became King Zheng of Qin (秦王政). By 221 BC, he had conquered all the other warring states and unified all of China, and he ascended the throne as China's first emperor. During his reign, his generals greatly expanded the size of the Chinese state: campaigns south of Chu permanently added the Yue lands of Hunan and Guangdong to the Sinosphere, and campaigns in Inner Asia conquered the Ordos Plateau from the nomadic Xiongnu, although the Xiongnu later rallied under Modu Chanyu.

Emperor Gaozu of Han (256 or 247 – 1 June 195 BC), personal name Liu Bang, was the founder and first emperor of the Han dynasty.

Liu Bang was among the few dynastic founders to have been born in a peasant family. He initially entered the Qin dynasty bureaucracy as a minor law enforcement officer in his hometown in Pei County, within the conquered state of Chu. During the political chaos following the death of Qin Shi Huang, who had been the first emperor in Chinese history, Liu Bang renounced his civil service position and became a rebel leader, taking up arms against the Qin dynasty. He outmanoeuvred rival rebel leader Xiang Yu to invade the Qin heartland and forced the surrender of the Qin ruler Ziying in 206 BC.

Qin's wars of unification were a series of military campaigns launched in the late third century BC by the state of Qin against the other six states remaining in China – Han, Zhao, Yan, Wei, Chu and Qi. Between 247 and 221 BC, Qin had developed into the most powerful of China's Seven Warring States that coalesced in the wake of the declining Zhou dynasty, which had been reduced to a weak and merely ceremonial position during the Warring States period. In 230 BC, Ying Zheng, the King of Qin, began the sequence of campaigns that would bring the Warring States period to a close, setting out to conquer each of the six states one by one. This was completed in 221 BC with the fall of Qi, which further led to a more centralised form of government replacing the fengjian system of the Zhou dynasty. Ying Zheng declared himself the First Emperor – or Shi Huangdi – of a unified China under the Qin dynasty.

The Seven Warring States or Seven Kingdoms (traditional Chinese: 戰國七雄; simplified Chinese: 战国七雄; pinyin: zhàn guó qī xióng) were the seven leading hegemonic states during the Warring States period (c. 475 to 221 BC) of ancient China:

• Han (韓/韩), defeated by Qin in 230 BCE
• Zhao (趙/赵), defeated by Qin in 228 BCE
• Wei (魏), defeated by Qin in 225 BCE
• Chu (楚), defeated by Qin in 223 BCE
• Yan (燕), defeated by Qin in 222 BCE
• Qi (齊/齐), defeated by Qin in 221 BCE
• Qin (秦)

During the Eastern Zhou dynasty, the weakened Zhou central sovereignty quickly lost control of its confederate vassal states, and the numerous autonomous states began overreaching and expanding their political ambitions via diplomacy and warfare, sparking a period of chaotic conflicts known as the Spring and Autumn period. After most of the smaller, weaker states were conquered and annexed by larger states, the geopolitical landscape eventually became dominated by seven most powerful states, and wars became increasingly pitched and violent. Over the Warring States period, many of the seven states underwent bureaucratic and military reforms in order to mobilise resources on a greater scale. This led to an intensification of warfare over the period, but also led to significant economic and cultural developments.

The Man, commonly known as the Nanman or Southern Man (Chinese: 南蠻; Jyutping: Naam4 Maan4; Pe̍h-ōe-jī: Lâm-bân, lit. Southern Barbarians), were ancient indigenous peoples who lived in inland South and Southwest China, mainly around the Yangtze River valley. In ancient Chinese sources, the term Nanman was used to collectively describe multiple ethnic groups, probably the predecessors of the modern Miao, Zhuang, and Dai peoples, and non-Chinese Sino-Tibetan groups such as the Jingpo and Yi peoples. It was an umbrella term that included any groups south of the expanding Huaxia civilization, and there was never a single polity that united these people, although the state of Chu ruled over much of the Yangtze region during the Zhou dynasty and was partly influenced by the Man culture.

The Heshibi, often translated as Mr. He's jade, was a sacred ceremonial bi disk, also known as a jade annulus, which had an important role in Chinese history. First appearing during the mid–8th century BCE, it was cut into a ritual bi and recognized as an imperial treasure. The Heshibi became the object of contention among the Warring States, stolen from Chu circa 4th century BCE, acquired by the Zhao, and temporarily traded to Qin in 283 BCE. When the Qin dynasty was founded in 221 BCE, the Heshibi was carved into the Heirloom Seal of the Realm, symbol of the Mandate of Heaven, and subsequently transferred through successive Chinese dynasties until it was lost during the Five Dynasties era in the 10th century.

The early historicity of the stone is uncertain, though its great antiquity seems clear. The earliest mention of it is from the 3rd century BCE. The story of its finding is likely apocryphal. Whether it was turned into the Heirloom Seal of the Realm is also a matter of dispute. If it was turned into the seal, it was certainly lost by the time of the Ming dynasty. It has been used as a metaphor for a precious object since its earliest mentions.

Old Chinese, also called Archaic Chinese in older works, is the oldest attested stage of Chinese, and the ancestor of all modern varieties of Chinese. The earliest examples of Chinese are divinatory inscriptions on oracle bones from around 1250 BC, in the Late Shang period. Bronze inscriptions became plentiful during the following Zhou dynasty. The latter part of the Zhou period saw a flowering of literature, including classical works such as the Analects, the Mencius, and the Zuo Zhuan. These works served as models for Literary Chinese (or Classical Chinese), which remained the written standard until the early twentieth century, thus preserving the vocabulary and grammar of late Old Chinese.

Old Chinese was written with several early forms of Chinese characters, including oracle bone, bronze, and seal scripts. Throughout the Old Chinese period, there was a close correspondence between a character and a monosyllabic and monomorphemic word. Although the script is not alphabetic, the majority of characters were created based on phonetic considerations. At first, words that were difficult to represent visually were written using a "borrowed" character for a similar-sounding word (rebus principle). Later on, to reduce ambiguity, new characters were created for these phonetic borrowings by appending a radical that conveys a broad semantic category, resulting in compound xingsheng (phono-semantic) characters. For the earliest attested stage of Old Chinese of the late Shang dynasty, the phonetic information implicit in these xingsheng characters which are grouped into phonetic series, known as the xiesheng series, represents the only direct source of phonological data for reconstructing the language. The corpus of xingsheng characters was greatly expanded in the following Zhou dynasty. In addition, the rhymes of the earliest recorded poems, primarily those of the Classic of Poetry, provide an extensive source of phonological information with respect to syllable finals for the Central Plains dialects during the Western Zhou and Spring and Autumn periods. Similarly, the Chu Ci provides rhyme data for the dialect spoken in the Chu region during the Warring States period. These rhymes, together with clues from the phonetic components of xingsheng characters, allow most characters attested in Old Chinese to be assigned to one of 30 or 31 rhyme groups. For late Old Chinese of the Han period, the modern Southern Min languages, the oldest layer of Sino-Vietnamese vocabulary, and a few early transliterations of foreign proper names, as well as names for non-native flora and fauna, also provide insights into language reconstruction.
