Eastern world
The division between "East" and "West" is from European cultural history.  There is a difference between European Christendom and the alien cultures beyond it to the East. With the European colonization of the Americas the East/West distinction became global. The idea of an Eastern, "Indian" (Indies) or "Oriental" sphere was made stronger by ideas of racial as well as religious and cultural differences. Such differences were shown by Westerners in the scholarly tradition known as Orientalism and Indology. People from the East are known by certain regions in the West as "Oriental". During the Cold War, the term "Eastern world" was sometimes used to mean the Eastern Bloc, which was the Soviet Union, China and their communist allies.  The term "Western world" often meant the United States and its NATO allies such as the United Kingdom. The idea is often another term for the Far East—a region that bears considerable cultural and religious sameness. Eastern philosophy, art, literature, and other traditions, are often found throughout the region in places of high importance, such as popular culture, architecture and traditional literature. The spread of Buddhism and Hindu Yoga is partly responsible for this.
