Western culture, also known as Western civilization, Occidental culture, or Western society, is the heritage of social norms, ethical values, traditional customs, belief systems, political systems, artifacts and technologies of the Western world. Western values become the symbols of dominant mentality for the culture of Western societies that transcended through power and authority. The term also applies beyond Europe to countries and cultures whose histories are strongly connected to Europe by immigration, colonization, or influence. For example, Western culture includes countries in the Americas and Oceania. Western culture is most strongly influenced by Greek philosophy, Roman law, and Christian culture.
