Every Chinese Emperor Explained (Part 2: Tang to Song): The Rulers Who Built the Golden Age

China's Tang Dynasty is called the greatest empire in the world at its time — and it was run by some of the most brilliant, brutal, and bizarre rulers in history. One emperor created the world's first meritocracy. Another was a woman who executed her own children to hold power. A third threw it all away for a concubine — and nearly lost the empire. But why did the Tang collapse — and why did the Song, which followed it, become even wealthier? Because the rulers changed everything. In this video, we break down every major emperor of the Tang and Song dynasties — their decisions, their wars, their failures, and the systems they built that shaped China for a thousand years.
