In this 100th episode of Trade Routes That Changed Human History Forever, Lucas and Luna explore the Kushan Empire, the often-overlooked middlemen who connected Han China, Parthian Persia, and Roman India for over two centuries. They discuss the rise of the Yuezhi nomads, the conquests of Kujula Kadphises and Kanishka the Great, the syncretic Gandharan art that blended Greek and Buddhist traditions, and the empire's role in spreading Mahayana Buddhism along the Silk Road. The episode also touches on the Begram treasure, a cache of Roman glass, Indian ivory, and Chinese lacquer found in modern Afghanistan, and the Kushan decline under the Sasanian Empire. Specific terms covered: Kushan Empire, Yuezhi, Kujula Kadphises, Kanishka the Great, Gandharan art, Mahayana Buddhism, Taxila, Begram treasure, Sasanian dynasty.
