Why each civilization from Greece was “classical”?

The civilization of ancient Greece was immensely influential in many spheres: language, politics, educational systems, philosophy, science, and the arts. It had major effects on the Roman Empire which ultimately ruled it. As Horace put it, "Captive Greece took captive her fierce conqueror and instilled her arts in rustic Latium."

Via the Roman Empire, Greek culture came to be foundational to Western culture in general. The Byzantine Empire inherited Classical Greek culture directly, without Latin intermediation, and the preservation of classical Greek learning in medieval Byzantine tradition exerted strong influence on the Slavs and later on the Islamic Golden Age and the Western European Renaissance. A modern revival of Classical Greek learning took place in the Neoclassicism movement in eighteenth- and nineteenth-century Europe and the Americas.

in the 1800s, chinese workers migrated to the united states, first to work in the gold mines, but also to take agricultural jobs, and factory work, especially in the garment industry. chinese immigrants were particularly instrumental in building railroads in the american west, and as chinese laborers grew successful in the united states, a number of them became entrepreneurs in their own right. as the numbers of chinese laborers increased, so did the strength of anti-chinese sentiment among other workers in the american economy. this finally resulted in legislation that aimed to limit future immigration of chinese workers to the united states, and threatened to sour diplomatic relations between the united states and china.
