Analysis of the oracular data newly discovered in the Shang era Huayuanzhuang site opens a fascinating window in the political and ritual activities of a prince previously unknown. He is identified as the prince Zai, the future king Zu Jia. These new data shed light of the pre-royal career of Zu Jia, and the nature and the mode of his relationship with the king Wu Ding, his father, and Lady Hao, his mother. This article also examines the difficult accession to royal power of Zu Jia in a context of political crisis. It studies and clarifies some of the steps leading to the selection of royal princes as heirs to royal power. Finally, this article examines the importance of the relationship between those princes and their mothers in the specific context of royal polygamy.

This article explores the political crisis before Wu Ding. The accession of king Wu Ding to the throne was not a given but the result of a political move by his father Xiao Yi. It must be seen as one of the consequences of an earlier political crisis named the “nine generations chaos” by Sima Qian, during which an attempt to share royal power between two royal lines finally collapsed and led to a move by Pan Geng to a new capital. This new city has recently been discovered north of the Huai river. The political crisis of the time led Shang kings to try to implement a unilineal system of succession. Other steps, ritual in particular, were involved after the reign of the king Zu Jia, one of the reigning sons of Wu Ding, in order to ensure the primacy of the unilineal system of royal succession.

Oracle bone script developed into a sophisticated writing system in Shang Dynasty of China more than 3000 years ago. The systematic scientific dating of oracle bones had not been previously reported. Here we present radiocarbon (14C) dates measured from the sequential samples of oracle bones that pertain to the Shang kings. The results indicate that King Wu Ding (who is called Wu Ting in some literature) reigned during 1254 BC to 1197 BC, and the Shang Dynasty terminated around 1041 BC. It also points that the Li group in the sequence of oracle bones is most probably related to the time of King Wu Ding and Zu Geng.

The Shang Dynasty has attracted much archaeological research, particularly the renowned ‘royal tombs’ of the Xibeigang cemetery at Anyang Yinxu, the last Shang capital. Understanding of the social strategies informing Shang mortuary practices is, however, very limited. A new reconstruction of the detailed chronology of the cemetery is presented here, allowing social theory to be applied, and reveals the strategic social decisions behind the placement of the tombs in relation to each other. The results of this analysis are important not only for the reconstruction of the social structure and organisation of the late Shang dynasty, but also for understanding the relationship between mortuary practices and the functioning of early states in other regions.

The importance of jade in the burnt offerings of the Shang Dynasty known as ‘Liao sacrifice’ has long been known from documentary evidence, but has yet to be scientifically verified. We present the results of non-destructive analyses of a jade parrot excavated from the tomb of imperial consort Fu Han at Yinxu in Henan Province. Analyses revealed the presence of diopside, an outcome of phase transition from tremolite resulting from heating in antiquity. This provides the first scientific evidence that the Shang Dynasty used jade in Liao sacrifice, and confirms oracle bone inscriptions and later records concerning the ritual.
