Civilization
A civilization (or civilisation) is a complex society or culture group characterized by dependence upon agriculture, long-distance trade, state form of government, occupational specialization, urbanism, and class stratification. Aside from these core elements, civilization is often marked by any combination of a number of secondary elements, including a developed transportation system, writing, standards of measurement (currency, etc.), formal legal system, great art style, monumental architecture, mathematics, sophisticated metallurgy, and astronomy.
