Description
The Emperor Huizong was captured by the Jurchens, and died in captivity. Later the Jurchens drove the Song out of northern China.
The Song Dynasty was established by a rebel general who overcame his later Zhou employer and went on to conquer the rest of the country. Military reforms produced two centuries of stability, but administrative costs reduced efficiency, and lack of preparedness invited invasion by the Jin from the north, while the Song moved their capital to the south.
The oldest Chinese coins are at least as old as the earliest Greek coins. The Chinese coinage system differed from other systems in two ways. It was monometallic, only bronze coins circulated in general commerce. Gold and silver were treated as commodities. And the manufacturing method was by casting in moulds rather than by striking heated solid planchets.
