Why China Reunified 5 Times but Rome Never Did

In the third century, Rome and Han China collapsed at almost the same time. Rome's fragments became permanent nations. China's fragments kept reassembling — five times across two thousand years. Why? The answer isn't culture or geography. It's a system invented in 221 BC that outlasted every dynasty that used it. This video traces how the First Emperor of Qin didn't just conquer six kingdoms — he reformatted an entire civilization, creating a political operating system so powerful that no period of division could ever become permanent. And why Rome's failure to do the same thing guaranteed that Europe would stay fragmented forever.
