China’s Qianlong Emperor commissions the largest library in imperial history
The Siku Quanshu, commissioned by China’s Qianlong Emperor in 1772, set out to gather every important book in the empire into one library. Over a decade, more than 361 scholars and nearly 3,826 scribes copied roughly 2.3 million pages by hand. It remains one of history’s most ambitious attempts to hold a civilization’s knowledge in one place.
