Western world
The Western world, also known as the West, primarily refers to various nations and states in the regions of Australasia, Europe, and the Americas. The Western world likewise is called the Occident () in contrast to the Eastern world known as the Orient (). The West is considered 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. Definitions for "Western world" vary according to context and perspectives. Modern-day Western world essentially encompasses the nations and states where civilization or culture is considered Western—the roots of which some historians have traced back to the Greco-Roman world. In the Global North–South schism, the West is often correlated with Global North. A historic idea of Europe as the geographic West emerged in fifth century BCE Greece. A geographical concept of the West started to take shape in 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. The Roman Constantine politico-religious division would eventually culminate in the East–West Schism in 1054 CE. Even though friendly relations continued between the two parts of the 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 European colonization of these newly discovered lands, an idea of the Western world, as an inheritor of Latin Christendom emerged. The English word "West" was initially meant an adverb for direction. By the Middle Ages, Europeans began to use it to describe Europe. Since the eighteenth century, following European exploration, the word was used to indicate the regions of the world with European settlements.
