Wu Ding (; died ); personal name (), was a king of the Chinese Shang dynasty who ruled the central Yellow River valley. He is the earliest figure in Chinese history mentioned in contemporary records. The annals of the Shang dynasty compiled by later historians were once thought to be little more than legends until oracle script inscriptions on bones dating from his reign were unearthed at the ruins of his capital Yin (near modern Anyang) in 1899. Oracle bone inscriptions from his reign have been radiocarbon dated to 1254–1197 BC ±10 years, closely according with regnal dates derived by modern scholars from received texts, epigraphic evidence, and astronomical calculations.

Wu Ding's reign is characterized by a prosperous period of the late Shang state, with a wide network of allies and subordinates. The first inscriptions unequivocally recognized as Chinese appeared during his reign, together with new technological innovations. More than half of Shang inscriptions date to his reign, concerning a wide variety of deities. In classical Chinese historiography, he is often depicted as a meritorious king.

Dating Because Wu Ding is the earliest Chinese ruler whose reign is confirmed by contemporary material, dating his reign is a matter of significant historical interest.

According to the traditional chronology, he reigned from 1324 to 1266 BC. This has been shown to be an artifact of incorrect backdating due to misunderstanding of King Wen of Zhou's Mandate calendar. In the Records of the Grand Historian, Han dynasty scholar Sima Qian wrote of his reign as beginning in the year , which can be either 1333 BC or 1273 BC according to the ganzhi calendar's 60-year repetition. The Guben Zhushu Jinian ("ancient version" of Bamboo Annals) gives Wu Ding's regnal dates as 1273–1213 BC. The Cambridge History of Ancient China gives 1189 BC as the end date of his reign based on records of lunar eclipses. The Xia–Shang–Zhou Chronology Project draft release (2000), sponsored by the Chinese government and disbanded without producing a final report, gives his reign as 1250–1192 BC. Inscriptions from twenty-six oracle bone divinations of his reign have been radiocarbon dated to 1254–1197 BC ±10 years. The methodology of the radiocarbon investigators involved accepting uncritically the purported reign length of 59 years attributed to Wu Ding in the transmitted record.

Life and reign Early life

The Shang dynasty practiced royal succession using a form of agnatic seniority, at times distributed across multiple lines of descent. In the generations preceding Wu Ding, succession had been split between the descendants of Zu Yi (祖乙) through his two sons Zu Xin (祖辛) and Qiang Jia (沃甲). This was interpreted by later historians as a weakening of an incorrectly reconstructed system of primogeniture. The Shang kings immediately preceding Wu Ding were three of his uncles (including the famous Pan Geng, who moved the capital to Huanbei) and finally his father, Xiao Yi. By the custom of the time, Xiao Yi could potentially have been succeeded by one of his second cousins from the alternate royal line. The fact that Xiao Yi was able to place his son on the throne despite the claims of a rival lineage may explain why Wu Ding built a new capital for the second time in living memory, as well as the transmitted tradition that he was sent away from the capital during his father's reign.

He happened to be Xiao Yi's only son, and therefore was created crown prince. The Bamboo Annals carry an entry stating that in the sixth year of his father's reign, Wu Ding was ordered to live at He () (ancient name for the Yellow River). Gan Pan (), a prominent minister in Xiao Yi's court, was chosen to be Zi Zhao's tutor. A late chapter in the Shangshu asserts that during these early years, he worked together with the local peasants. The times spent among the common people allowed Wu Ding to become familiar with their daily problems, which affected the ruling methods of the future king.

King of the Shang dynasty

In Sima Qian's Shiji he was listed as the twenty-second Shang king. Oracle bone script inscriptions unearthed at Yinxu alternatively record that he was the twenty-first Shang king. The Shiji says that he was enthroned with Yin () as his capital.

Although his ruling period was characterized with wars, traditional Chinese historiography still portrayed him as a virtuous monarch who showed great care to his country. Chapter XXI of the Book of Documents describes him remaining silent in the beginning of his reign as to cultivate his virtue. According to the text, Wu Ding restrained himself from speaking even after his three-year mourning for his father's death (during which all the state affairs were discussed and managed by his court ministers) had ended:

(By referring to this anecdote, classical historians emphasized his righteousness, filial piety and the desire to be an upright ruler like his predecessors.)

According to the Bamboo Annals, in the twenty-fifth year of his reign, his son Zu Ji () died in a remote area after being exiled.

Participation in Shang religious activities

Later Chinese historians when referring to him tended to emphasize his oversight of ceremonies through romanticized anecdotes. According to the Book of Documents, in the twenty-ninth year of his reign, he conducted rituals in honour of his ancestor Da Yi (), the first king of the Shang dynasty, at the Royal Temple. When he saw a crowing pheasant on one of the ceremonial bronze vessels, he became frightened and considered it an ominous omen. Zu Ji, who was accompanying his father during the rituals, is said to have wanted to advocate religious modifications. Following this thought, Zu decided to discuss the omen with his father. He was quoted as saying:

Wu Ding was actively involved in divination and sacrifice. The king, with the assistance of his priests, was responsible for a large proportion of oracle bone divinations found at Yin. Wu Ding specifically divined about his queen, both when she was alive and after her departure. In particular, one inscription on Fu Hao's being pregnant said that the conception was "inauspicious" (that the child was a girl). Aside from pregnancy, he also divined on her health, prosperity, as well as praying for her in the afterlife. (He is believed to have married her three more times to his ancestors, since he believed they would act as her guardians after death). He also asked divinatory questions about human sacrifice as well as warfare. He also seemed to be in awe of his ancestors, especially his second uncle Pan Geng. He regularly wrote questions concerning weather, agricultural issues for his deceased predecessors, and he held a thought that they were capable of indirectly supporting his army in battles. Moreover, Pan Geng was specifically perceived to be involved in his nephew's health. One example based on contemporary records is a reconstructed ceremony by Keightley, which aimed to seek improvement for Wu's dental problems. In the ritual, Wu Ding offered one dog and one sheep to Pan Geng and tried to convince him to treat his toothache.

Oracle bones often include the names of diviners. Wu Ding divined exceptionally many times; numerous bone texts feature the king himself as the chief diviner. He interpreted the cracks on oracle bones to predict future events, of which four notable examples are:

Crack-making divination on the day guiwei: Wu's assistants predicted no disaster, but he divined that the near future would be misfortune. It is purportedly said that six days after, a relative of Wu died. The relative was possibly Zu Ji, although the texts do not specify his identity. He allegedly died on wuzi day of the First Month. Another time, he interpreted the signs as negative. It is said that eight days later, the Sun was covered by large clouds, and a rainbow appeared in the Yellow River. Divinations on wars and territorial defense: on the day guisi, Wu Ding predicted the opposite future from his diviners that confrontational polities were going to launch attacks on his border. On the day dingyou, it is believed that bad news came from the West from a trusted regional lord, Guo. The lord reported that Tu Fang had attacked the territory and destroyed two towns, and another tribe had taken over the kingdom's western fields. However, this is somewhat contradictory, since Tu Fang supposedly mobilized its men from the east, contrary to their location northwest of Yin. A prediction of disasters gave the outcome that one of Wu Ding's accompanying ministers would fall off his chariot during a hunting expedition. The misfortune occurred on jiawu day, when the king was seeking for a rhinoceros. Two people, one of his xiaochen (petty ministers) and his child fell off their chariots.

The divinations of the scribes often included the prediction of fortune in a certain period (usually a Shang week). An ox scapula records the divinations by Zheng (), one of the Bīn () group of diviners serving Wu Ding. On the piece of bone, four separated divinations were carved (either by the king or Zheng himself):

On the top: "... divined: In the next ten days (week), there will be no disasters." On the left: 。 "guǐmǎo (day 40) Zheng divined: in the next ten days there will be no disasters. jiǎchén (day 41) ... strong gale, evening cleaved to yǐsì (day 42), captured ... five people. Fifth month, in Dun." On the middle: "guǐchǒu (day 50) Zheng divined: in the next ten days there will be no disasters." The character (king) indicates the personal involvement of Wu Ding in this specific divination. Wu Ding added to Zheng's conclusion that there would be ominous spirits, and on the day jiayin there would be obstacles. On the right: "guǐchǒu (day 50) Zheng divined: in the next ten days there will be no disasters. Third day, yǐmǎo (day 52) ... dīngsì (day 54) ... Gui will also have sickness."

Wu Ding's family also played a part in religious practice. They appeared to have been granted their own power as priests, and some oracle texts carved by the assistants might have been made in the service of the princes. The majority (70%) of oracle characters date back to Wu Ding's reign, which indicates his emphasis on religion.

First chancellor Gan Pan

It is believed that two individuals were chosen as administrative chancellors by this king. Several texts state that after becoming king, Wu Ding appointed his former tutor, Gan Pan (), as the chief minister at his court. Gan began to arrange the military formations of the country while also acting as an adviser to the new ruler. In the work "Shangshu Zhengyi", Kong Anguo mentioned Gan Pan as an exemplary minister that could be compared with Yi Yin. The Book of Documents makes the same comparison in its chapter on the Duke of Shao, who would act as one of the Three Regents under King Cheng of Zhou approximately 250 years after Gan Pan. In the text, the Duke of Zhou is quoted as delivering a lesson about Shang meritorious officials that ought to be viewed as models of loyal and capable ministers:
