When King Tang of Shang established the Shang Dynasty, he first set the capital at Bo (present-day Shangqiu, Henan). From the founding of the state by Cheng Tang to its fall under Emperor Xin (King Zhou), the dynasty passed through seventeen generations and thirty-one kings, spanning over 600 years. During the first 300 years of this period, the Shang moved its capital five times. The Eastern Han scholar Zhang Heng wrote in his "Western Capital Rhapsody": "The Yin people frequently relocated, eight times before and five times after." The "eight times before" refers to the eight migrations of the Shang tribe before the dynasty's establishment, while the "five times after" refers to the five capital moves after Tang founded the Shang. These five relocations are recorded in the ancient text "Bamboo Annals": King Zhong Ding moved the capital from Bo to Xiao, He Jia moved from Xiao to Xiang, Zu Yi settled at Bi, Nan Geng moved from Bi to Yan, and Pan Geng moved from Yan to Beimeng, which was called Yin.
Thousands of years ago, with backward productivity, humans lacked the ability to withstand natural disasters. When floods, droughts, or other calamities struck, the least consequence was the complete destruction of living environments, and the worst was the extinction of entire communities. To find suitable places for survival, many tribes had to migrate frequently, which was also the reason for the Shang tribe's repeated relocations. However, after the establishment of the Shang Dynasty, humanity had advanced from the Stone Age to the Bronze Age, and productivity had greatly developed. So why did they still move their capital multiple times?
Looking at the frequent capital relocations in Shang Dynasty history, the time period mainly concentrated during the reigns of the nine kings from Zhong Ding to Pan Geng. According to the "Records of the Grand Historian: Annals of Yin," it is recorded: "Since Zhong Ding, the rightful heir was set aside and other sons and brothers were established instead, with disciples sometimes contending to take over, leading to nine generations of chaos, and as a result, the feudal lords no longer paid court." Yi Yin, relying on his talents, assisted five Shang Dynasty monarchs, laying the foundation for the dynasty's golden age. However, precisely because the state was stable, the people lived in peace, and the world was at peace, the monarchs felt they could indulge in pleasure, thus fostering a style of greed for enjoyment and excessive luxury. The Shang Dynasty's succession system gave brothers priority inheritance rights, with the throne passing to sons only if there were no brothers, so many people eyed the throne covetously. Starting from Zhong Ding, royal descendants intensified their struggles for the throne, political turmoil continued incessantly, royal power weakened day by day, national strength declined, some small states and ethnic minorities took the opportunity to rebel, and coupled with constant natural disasters like floods and droughts, the Shang royal rule fell into a crisis of internal and external difficulties. For the monarchs, moving the capital at this time was the best choice to shift the crisis and escape difficulties. After the Shang Dynasty was established, the capital was moved multiple times. By the time Yang Jia ascended the throne, the capital had already been moved to Yan. At this point, the Shang royal family was excessively luxurious, internal power and interest struggles escalated daily; slave owners lived a life of extravagance and debauchery, while slaves suffered cruel exploitation, with many slaves unable to bear it and fleeing, sharpening class contradictions; the feudal lords in all directions also rebelled one after another, plunging the country into chaos. It was at this moment that Yang Jia died, and his younger brother Pan Geng succeeded him. From Zhong Ding to Pan Geng, having gone through the "Nine Generations of Chaos," the Shang Dynasty's rule was nearly on the verge of collapse.
Pan Geng, known as Ban Geng in oracle bone inscriptions, with the personal name Xun, was the son of Zu Ding and the younger brother of Yang Jia. He was the ninth-generation descendant of Shang Tang and the twentieth king of the Shang Dynasty. According to the Revised Chronology of the Xia, Shang, and Zhou Dynasties, his reign lasted from 1300 BC to 1277 BC, a total of 28 years, and he was a highly capable king. Ascending the throne during turbulent times, Pan Geng possessed a strong sense of crisis. He keenly observed the chaos in the state and the suffering of the people, realizing that if things continued this way, the Shang Dynasty would soon face its downfall. To ease social tensions, escape political difficulties, and save the Shang Dynasty from decline, Pan Geng decided to abandon the already prosperous capital of Yan and choose a place where long-term development could revive the dynasty's rule.
He sent people to investigate various places and learned that the northern region of Meng (present-day Anyang, Henan), though sparsely populated and undeveloped, had fertile land and abundant water, with wild animals in the mountains and fish and shrimp in the rivers—natural conditions far superior to the low-lying Yan as a capital. Moreover, moving the capital there could curb the extravagance of the nobility, ease class tensions, and reduce the impact of natural disasters. Thus, Pan Geng decided to relocate the capital to northern Meng, using the opportunity to resolve all conflicts at once. However, as soon as Pan Geng's decision to move the capital was announced, it immediately faced opposition from most of the nobility. The royal family and nobles feared that after the move, their privileges would be weakened; coupled with the bustling prosperity of Yan, they were reluctant to leave their comfortable lives and start over in the desolate northern Meng. Some nobles even incited the common people to oppose the move to stop Pan Geng, and soon Pan Geng was surrounded by voices of dissent. Despite this, Pan Geng firmly believed that moving the capital could strengthen and consolidate his rule, so his resolve was unwavering. To rally support for the relocation, he gathered the slave-owning nobles and delivered an important speech, explaining the benefits of moving the capital. He cited examples of "our ancient former kings" who "reverently followed the mandate of heaven," emphasizing the inviolability of heaven's will and arguing that the move was in accordance with it, thereby quelling discontent. People in slave society were highly superstitious about divine authority, so Pan Geng's appeal to heaven's mandate was effective in winning hearts. In his speech, he rebuked the ministers for neglecting their duties and failing to make the people understand the profound purpose of the move, leading to unrest and unnecessary trouble; he sternly condemned the royal nobles for their greed for comfort and unwillingness to relocate, and firmly stated that anyone who disobeyed the order to move would face severe punishment. Then, Pan Geng's tone softened, and he cited examples from ancient times when rulers and ministers trusted each other and worked together to make the country prosperous and the people strong, hoping that his ministers would unite with him to overcome the current difficulties. His speech was reasonable and highly persuasive, reflecting the vision and boldness of a far-sighted ancient statesman.
Later, his speeches were recorded and included in the Book of Documents, and idioms still commonly used today, such as "a single spark can start a prairie fire" and "in an orderly manner," were distilled from his words. Pan Geng's determination to move the capital was resolute, ultimately overcoming the opposing forces. In the third year of his reign, 1298 BCE, Pan Geng led commoners and slaves across the Yellow River westward, moving in great numbers to Beimeng, an event historically known as "Pan Geng's Relocation of the Capital."
Later, the northern region of Meng was renamed Yin, so this event is also known as "Pan Geng's relocation to Yin." After the move, the people struggled to adapt to the new location, and the nobles exploited this discontent, pressuring Pan Geng through the populace to return to the old capital. Pan Geng firmly suppressed such efforts and began reorganizing Shang Dynasty politics in the new capital. He consciously absorbed the governance wisdom of his predecessors, as reflected in the saying, "Our ancient kings always ensured the people's well-being," believing that to earn the people's support, a ruler must share their joys and hardships. Thus, he prioritized understanding the people's needs, implemented relatively enlightened policies, and selected officials with the people's interests in mind, appointing only those who cherished the populace. He required officials to always harbor a heart of love for the people and urged the noble clans to set aside selfishness and extend kindness to the people. Soon, Yin flourished into a prosperous political and economic center.
According to the "Annals of Yin" in the Records of the Grand Historian, after moving the capital to Yin, Pan Geng "implemented the policies of Tang," restoring the prosperous scene where "the people were at peace" and "the feudal lords came to pay tribute," completely reversing the chaos caused by the "Nine Generations of Turmoil," leading to a situation where the people lived and worked in contentment, society was wealthy and prosperous, and the declining Shang Dynasty was thus revived.
Pan Geng, as a king of the Shang Dynasty, accomplished the great feat of relocating the capital through his far-sighted vision, laying the foundation for the prosperous era of Wu Ding and earning the title of a "restoration" ruler. Before moving to Yin, the Shang had shifted their capital several times, but after Pan Geng's move to Yin, the capital remained there for over 270 years until the dynasty's fall, which is why the Shang is also called the Yin Dynasty or Yin-Shang. This shows that Pan Geng's decision to relocate the capital to Yin, despite widespread opposition, was exceptionally wise.
