While the Warring States Period developed in China, the city-states system in the Greek Peninsular entered a period of crisis (404–338 BCE). In 346 BCE, when Shang Yang, chancellor of the State of Qin, had almost finished his reform of the junxian system, remote Athens was undergoing the “Pan-Hellenistic movement,” at the center of which was a man named Isocrates (436–338 BCE), the leading orator of Athens. He is reported to have studied with several prominent teachers, including Tisias (one of the traditional founders of rhetoric), the sophists Prodicus and Gorgias, and to have associated with Socrates. He defined for the Greek world the form of rhetorical proses, which was later imitated by Cicero, a Roman orator and statesman.
