Anenemhatat I establishes (probably by a coup) Egypt’s Twelfth Dynasty in 1991, subdues the Egyptian nobility and restores prosperity.

A vizier of his predecessor Mentuhotep IV, Amenemhat I has overthrown him and established the Twelfth Dynasty of Egypt, claiming descent from Amun, a local god of his native Thebes.

The usurper moves the capital from Thebes to …

The first known ruler of Ebla in this period is Megum, an Ensi (governor) for Ur III during the reign of Amar-Sin of Ur, who reigned in around 1981 BCE to 1973 BCE (short chronology).

Ibbit-Lim, an Amorite prince of Ebla, is the first attested king, though sources are divided as to whether he was a king in Ebla or of Mari.

A reasonable suggestion is that he ruled in Ebla as king of Mari at a time of Amorite domination of Ebla, thus placing the city under Mari's control.

The armies of Amenemhat I campaign south as far as the Second Cataract of the Nile and into the Near East.

Amenemhat reestablishes diplomatic relations with Byblos and the rulers in the Aegean Sea.

Amenemhat’s son Senusret I, who rules from 1971 BCE to 1926 BCE, follows his father's triumphs with an expedition south to the Third Cataract.

Maritime East Asia (1917–1774 BCE): The Erlitou Culture and Early Bronze Age Developments

Between 1917 BCE and 1774 BCE, Maritime East Asia—comprising lower Primorsky Krai, the Korean Peninsula, the Japanese Archipelago below northern Hokkaido, Taiwan, and southern, central, and northeastern China—sees significant cultural and technological developments marked prominently by the rise and spread of the influential Erlitou culture. This early Bronze Age society, named after its principal archaeological site at Erlitou in Yanshi, Henan Province, represents a crucial stage in the evolution of complex urban societies and metallurgy in ancient China.

Rise and Spread of the Erlitou Culture

The Erlitou culture flourishes roughly between 2000 BCE and 1500 BCE, with its largest and most influential site located at Erlitou itself, spanning approximately three kilometers in diameter. This prominent settlement likely serves as a central hub for ritual, political, and economic activity, notably monopolizing the sophisticated production of ritual bronze vessels. These vessels become distinctive markers of Erlitou craftsmanship, signaling the emergence of specialized metallurgy and advanced artisan traditions during China’s early Bronze Age.

Geographic Expansion and Regional Influence

Originating from antecedent late-Neolithic Longshan cultural traditions, Erlitou rapidly expands its cultural influence beyond Henan Province, spreading significantly throughout neighboring regions including Shanxi, and subsequently influencing areas of Shaanxi and Hubei provinces. The widespread geographic distribution of Erlitou cultural artifacts—particularly ritual bronzes—suggests extensive regional networks of trade, cultural exchange, and possibly political alliances or control extending throughout central and northeastern China.

The Erlitou Culture and the Xia Dynasty Debate

A significant scholarly debate centers on Erlitou’s potential association with the legendary Chinese Xia Dynasty, traditionally described in historical texts but not conclusively linked to archaeological sites. Most Chinese archaeologists consider Erlitou the physical manifestation of the Xia Dynasty, citing chronological alignment and geographic coherence with textual descriptions. In contrast, many Western archaeologists remain cautious, emphasizing the absence of written records directly linking the Erlitou archaeological findings with the historical narrative of the Xia Dynasty.

This debate underscores the importance of Erlitou as a key archaeological culture bridging prehistoric traditions and historical accounts, regardless of its direct dynastic connections.

Legacy of the Era: Foundations of Urbanization and Bronze Technology

Thus, the period from 1917 BCE to 1774 BCE marks a pivotal chapter in the historical trajectory of Maritime East Asia, particularly within China’s central and northeastern regions. The emergence and regional expansion of the Erlitou culture signify critical transitions toward urban complexity, sophisticated metallurgical practices, and increased social stratification. These innovations lay lasting foundations for subsequent cultural and historical developments across Lower East Asia.

Trade in goods formerly considered exotic increases in this age, in conjunction with organized exploitation of natural and native resources by colonizing nations.

Cross-cultural pollination occurs in religion and philosophy, as well as in technologies and the arts.

The Erlitou culture, a name given by archaeologists to an Early Bronze Age society that exists in China from 2000 BCE to 1500 BCE, is named after the site discovered at Erlitou in Yanshi, Henan Province.

Erlitou, at three kilometers in diameter the largest site associated with the culture, apparently monopolizes the production of ritual bronze vessels.

The Erlitou culture, which may have evolved from the Longshan culture, is widely spread throughout Henan and Shanxi Province, and will later appear in Shaanxi and Hubei Province.

Most Chinese archaeologists identify the Erlitou culture as the site of the Xia Dynasty, while most Western archaeologists remain unconvinced of the connection between the Erlitou culture and the Xia Dynasty since there are no extant written records linking Erlitou with the official history.

The Tarim Basin, surrounded by mountains, may be one of the last places in Asia to have become inhabited.

Its aridity required the development of technology for water transport and storage before people could live here.

The lake system into which the Tarim River and Shule River empty is the last remnant of the historical post-glacial Tarim Lake, which once covered more than ten thousand square kilometers (thirty-nine hundred square miles) in the Tarim Basin.

Lop Nur, a group of small, now seasonal salt-lake sand marshes between the Taklamakan and Kuruktag deserts in the southeastern portion of Xinjiang Uygur Autonomous Region in the People's Republic of China, is hydrologically endorheic—it is landbound and there is no outlet.

The lake from around 1800 BCE supports a thriving Tocharian culture that will last until the ninth century.
