Zu Jia (祖甲) (died in the middle of the 12th century BC) or Di Jia (帝甲), personal name Zǐ Zǎi (子載), was a Shang dynastyKing of China. He was the third recorded son of Wu Ding, the first Chinese monarch verified by contemporary records. Having inherited a large area of lands conquered by his father and brother, he led the Shang kingdom through the last brief period of stability. After his reign, Shang went into irreversible decline.
Zu Jia reigned during the first half of the 12th century BC, from the city of Yin, the ancient historical capital of Shang. He is known to have started religious and successive reforms to solve previously concerned problems. His period marked the rise of Predynastic Zhou, which began to develop more complex relations with the Shang court after Wu Ding's death.[2]
Early life
Little is known about Zu Jia's early life. He was a royal member of the Shang dynasty, which had been ruling the Yellow River valley from the 16th century BC. He was one of three male children of Wu Ding, born by Wu's principal queen consort, Fu Jing. He had two older brothers, Zu Geng, Zu Ji, and a sister, Xiao Chen Tao.
His father Wu Ding was one of the most notable Chinese ruler of the Shang dynasty. After over 59 years from 1250 BC, Wu transformed Shang from a declining country into a powerful state, expanding influence out of the Yellow River to reach faraway lands of the Yangtze and modern Shaanxi. Zu's eldest brother Zu Ji (祖己) was titled "Xiaowang" (小王, "Expectant King") and appointed Wu Ding's successor. Zu Ji died early, and was replaced by Zi Yue, or later known as Zu Geng. During Zu Geng's reign, the prince Zi Zai became the Expectant King.[3]
Reign as king
Zu Jia succeeded his brother, resuming Shang's tradition of fraternal succession. The Xia-Shang-Zhou Chronology Project places Zu Jia's reign at 1184 - 1177 BC. The Bamboo Annals (竹書紀年) gives another time frame, which David Nivison identified as 1177 - 1156 BC.[4] The year of his succession, according to Nivison, explains his regnal name. According to the Shang dynasty's naming rules, the king's regnal era was named after the first day in the year of succession.[5] 1177 BC began with a gui day in sexagenary cycle. The gui name was taboo since it coincided with the name the Shang ancestor Zhu Gui (主癸, father of Cheng Tang). As a result, the next day of gui, jia, was chosen to be regnal name. The other character Zu was used to distinguish the king from other monarchs who shared the same jia name.
His capital was at Yin (殷). The city was traditionally traced back to Pan Geng, Zu Jia's great uncle who is credited to have founded Yin around 1300 BC. In Wu Ding's time, Yin flourished and became the political as well as cultural center of the kingdom.
His father had reassured and firmly established Shang suzerainty over a large area. When Wu died, Zu Geng conquered and destroyed the remaining remnants of confrontational tribes that had not been fully subdued. Zu Jia, consequently, inherited a powerful country with numerous vassal states.
In the 12th year of his reign, he sent troops to fight Rong people in the west until winter.
In the 13th year of his reign, after being defeated, the West Rong people sent an envoy to Shang. In the same year he ordered the vassal of Fen (邠) to establish an army at Gan (绀).
In the 24th year of his reign, he reproduced the Penalties that were used by Tang of Shang to repress the rebellion.
Oracle bone inscriptions of his reign show that he changed some aspects of Shang religion. His modification targeted at sacrifices. Decades before, Wu Ding had reformed the sacrificial system by restricting the number of sacrifice to ancestors; the situation in which he announced the reform is recorded in the Book of Documents (Shangshu). Zu Jia critically reversed the reform, increasing ancestral sacrifices in terms of number, while reducing sacrifices to mythical spirits.[6]
Succession rule alterations
In the 27th year of his reign, he named his twin sons as prince Zi Xiao (子嚣) and Zi Liang (子良).
The Shang followed the rule of fraternal succession throughout many generations. The tradition was first practiced by Cheng Tang's offspring, who passed it down to subsequent rulers. Nivison claimed that this was done in order to prevent the risk of outside interference; he derived the theory from the Bamboo Annals, which contains an entry detailing Yi Yin's usurpation of the throne from Tai Jia. The convention continued to Wu Ding, who might have followed it providing that he had living siblings or cousins. Wu Ding, however, due to his 59-year reign, had outlived all possible candidates. He had to rely on his children. Zu Ji predeceased his father, so Zu Ding and Zu Jia were the only two options. From Zu Geng, agnatic seniority was again applied to succession. That posed a new threat of fraternal usurpation.[7] Zu Jia solved the problem by directly granting his chosen heir a royal ganzhi name, thus ensure stability.
Sima Qian's Records of the Grand Historian states that succeeding Zu Jia was his son Lin Xin. However, the Bamboo Annals says that Lin Xin had died before his father, and therefore did not become king. Instead, the successor was his other son Zi Xiao, who was granted the title "Geng Ding" used later as the regnal name.
Family
The Shang was only documentarily verified from Wu Ding. However, the essentially developed status of the civilization from that time indicates that there were actual kings before Wu. The list below presents Zu Jia's family in five generations.
Pan Geng, 18th Shang king. Traditionally regarded to be the founder of the Shang capital Yin.
Xiao Xin, 19th Shang king. His reign saw the kingdom declining and losing dominance.
Father: Wu Ding, reportedly succeeded the throne on January 4, 1250 BC or 1247 BC. He was an excellent monarch who restored the Shang and brought back its lost glory.
Mother: Fu Jing, one of Wu Ding's three Principal wives. She acted as a priestess and a general in Wu Ding's court. Her position was similarly equal to Fu Hao's.
The Xia-Shang-Zhou Chronology Project gives his death year as 1177 BC, several years after his accession. The Bamboo Annals' information is interpreted and produce 1156 BC as the outcome. After his death, he was given a royal funeral, organized by his immediate heir (recorded as Lin Xin or Geng Ding) and buried in the Shang royal cemetery at Xibeigang.[8]
Like his brother Zu Geng, Zu Jia was one of the first Shang kings to be buried in the cemetery's West zone. The section was founded by Wu Ding, aimed to separate Wu's successors from his ancestors. Zu Jia was interred in Tomb 1003, near his brother's tomb (1004). His tomb formed a cluster with that of Zu Ji and Zu Geng,[9] and was positioned so that he could pay respect to his predecessors.
