Later Jin

Capital: Kaifeng

History

The Later Jin (936–947 AD), the third of the Five Dynasties, holds a uniquely infamous place in Chinese history for setting a devastating geopolitical precedent that would haunt the Central Plains for over four hundred years. The dynasty was born out of treachery when Shi Jingtang, a powerful Shatuo Turk general serving the Later Tang, rebelled against his emperor.

Facing imminent defeat, Shi Jingtang made a desperate and highly controversial pact with Yelü Deguang, the emperor of the powerful Khitan Liao Dynasty to the north. In exchange for the massive Khitan military intervention that allowed him to destroy the Later Tang and seize the throne, Shi Jingtang agreed to two humiliating conditions.

First, despite being ten years older, he formally submitted to the Khitan ruler as a 'Son Emperor' (Erhuangdi), paying vast annual tributes of silk and wealth. Second, and far more disastrously, he permanently ceded the Sixteen Prefectures of Yanyun (a region encompassing modern-day Beijing and northern Hebei/Shanxi).

This cession handed the Khitans control of the strategic mountain passes and the Great Wall, stripping northern China of its natural geographical defenses and leaving the heartland entirely exposed to nomadic cavalry invasions. As long as Shi Jingtang lived, he obediently maintained this servile relationship, keeping his fragile regime afloat.

However, upon his death, his fiercely anti-Khitan nephew and successor, Shi Chonggui, foolishly attempted to assert independence, famously declaring himself a 'Grandson' rather than a 'Vassal' to the Khitan emperor and refusing to pay tribute. Enraged by this insolence, the Khitan Emperor launched a series of brutal, large-scale invasions.

Stripped of the Sixteen Prefectures' defenses, the Later Jin army was ultimately outmaneuvered and crushed. In 947, Khitan forces swept into the capital of Kaifeng, captured the emperor, and unceremoniously extinguished the Later Jin dynasty, plunging the region into even deeper turmoil.
