Civilization

Civilization  refers to either: 1) the procession of human societies generally toward more development and use of more complex technology, higher population densities, increasing per capita gross domestic product, and other significant advancements; or 2) any human society (for example, "Ancient Greek Civilization") associated with any particular geographical location at a particular time, historical or current. (When used in this second sense, the word is often restricted to apply only to societies that have attained a particular level of advancement, especially the founding of cities, with the word "city" defined in various ways.) The level of advancement of a civilization is often measured by its progress in agriculture, long-distance trade, occupational specialization, and urbanism. 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.), contract and tort-based legal systems, characteristic art styles (which may pertain to specific cultures), monumental architecture, mathematics, sophisticated metallurgy, and astronomy.
