Westernization (US) or Westernisation (UK) (see spelling differences), also Europeanization/Europeanisation or occidentalization/occidentalisation (from the Occident, meaning the Western world; see ), is a process whereby societies come under or adopt Western culture in areas such as industry, technology, law, politics, economics, lifestyle, diet, clothing, language, alphabet, religion, philosophy, and values. Westernization has been an accelerating influence across the world in the last few centuries, with some thinkers assuming westernization to be the equivalent of modernization, a way of thought that is often debated. The overall process of westernization is often two-sided in that Western influences and interests themselves are joined with parts of the affected society, at minimum, to change towards a more Westernized society, in the hope of attaining Western life or some aspects of it. To assume, however, Western societies are not affected or changed by this process and interaction with non-Western groups is misleading.
Westernization traces it roots back to Ancient Greece, the birthplace of Western culture. As Ancient Greece flourished, a new Empire was emerging namely Roman. The Roman Empire would take on the first process of Westernization as it was heavy influenced by Greece and created a new culture based on the principles and values of the Ancient Greek society. The Romans emerged with a culture that would lay the new foundations of Europe and create the new western identity based on the Greco-Roman society.
