Occident in the context of "Western World"

The Western world, also known as the West, primarily refers to various nations and states in Western Europe, Northern America, and Australasia; with some debate as to whether those in Eastern Europe and Latin America also constitute the West. The Western world likewise is called the Occident (from Latin occidens 'setting down, sunset, west') in contrast to the Eastern world known as the Orient (from Latin oriens 'origin, sunrise, east'). Definitions of the "Western world" vary according to context and perspectives; the West is an evolving concept made up of cultural, political, and economic synergy among diverse groups of people, and not a rigid region with fixed borders and members.

Some historians contend that a linear development of the West can be traced from Ancient Greece and Rome, while others argue that such a projection constructs a false genealogy. A geographical concept of the West started to take shape in the 4th century CE when Constantine, the first Christian Roman emperor, divided the Roman Empire between the Greek East and Latin West. The East Roman Empire, later called the Byzantine Empire, continued for a millennium, while the West Roman Empire lasted for only about a century and a half. Significant theological and ecclesiastical differences led Western Europeans to consider the Christians in the Byzantine Empire as heretics. In 1054 CE, when the church in Rome excommunicated the patriarch of Byzantium, the politico-religious division between the Western church and Eastern church culminated in the Great Schism or the East–West Schism. Even though friendly relations continued between the two parts of Christendom for some time, the crusades made the schism definitive with hostility. The West during these crusades tried to capture trade routes to the East and failed, it instead discovered the Americas. In the aftermath of the European colonization of the Americas, primarily involving Western European powers, an idea of the "Western" world, as an inheritor of Latin Christendom emerged. According to the Oxford English Dictionary, the earliest reference to the term "Western world" was from 1586, found in the writings of William Warner.

The Orient is a term referring to the East in relation to Europe, traditionally comprising anything belonging to the Eastern world. It is the antonym of the term Occident, which refers to the Western world.

In English, it is largely a metonym for, and coterminous with, the continent of Asia – loosely classified into Southwest Asia, Southeast Asia, South Asia, Central Asia, East Asia, and sometimes including the Caucasus. Originally, the term Orient was used to designate only the Near East, but later its meaning evolved and expanded, designating also Central Asia, Southwest Asia, South Asia, Southeast Asia, or the Far East.

Westernization (or Westernisation, see spelling differences), also Europeanisation or occidentalization (from the Occident), is a process whereby societies come under or adopt what is considered to be Western culture, in areas such as industry, technology, science, education, politics, economics, lifestyle, law, norms, mores, customs, traditions, values, mentality, perceptions, diet, clothing, language, writing system, religion, and philosophy. During colonialism it often involved the spread of Christianity. A related concept is Northernization, which is the consolidation or influence of the Global North.

Westernization has been a growing 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 become a more Westernized society, with the putative goal of attaining a Western life or some aspects of it, while Western societies are themselves affected by this process and interaction with non-Western groups.

Seyyed Jalāl Āl-e-Ahmad (Persian: جلال آل‌احمد; December 2, 1923 – September 9, 1969) was a prominent Iranian novelist, short-story writer, translator, philosopher, socio-political critic, sociologist, as well as an anthropologist who was "one of the earliest and most prominent of contemporary Iranian ethnographers". He popularized the term gharbzadegi – variously translated in English as "westernstruck", "westoxification", and "Occidentosis" – producing a holistic ideological critique of the West "which combined strong themes of Frantz Fanon and Marx".
