I made this little cheater for myself to keep straight in my mind where Afghanistan really is, geographically. It is in the middle of Eurasia, a transition point, which means everyone wants control.
The following countries and areas comprise the West Asia subregion: AFGHANISTAN, Armenia, Azerbaijan, Bahrain, Cyprus, Gaza Strip, Georgia, Iran (Islamic Republic of), Iraq, Israel, Jordan, Kuwait, Lebanon, Oman, Qatar, Saudi Arabia, Syrian Arab Republic, Turkey, United Arab Emirates, West Bank and Yemen.
The Middle East is a transcontinental region in Afro-Eurasia which generally includes Western Asia (except for Transcaucasia), all of Egypt (mostly in North Africa), and Turkey (partly in Southeast Europe).
Modern definitions of South Asia are consistent in including AFGHANISTAN, India, Pakistan, Bangladesh, Sri Lanka, Nepal, Bhutan and Maldives as the constituent countries. AFGHANISTAN is, however, considered by some to be a part of Central Asia, Western Asia, or the Middle East.
Byzantium was an ancient Greek city in classical antiquity that became known as Constantinople in late antiquity and Istanbul today. The Greek name Byzantion and its Latinization Byzantium continued to be used as a name of Constantinople sporadically and to varying degrees during the thousand year existence of the Byzantine Empire. Byzantium was colonized by the Greeks from Megara in 657 BC, and remained primarily Greek-speaking until its conquest by the Ottoman Empire in AD 1453.
Istanbul . . .historically known as Byzantium and Constantinople, is the largest city in Turkey and the country’s economic, cultural and historic center. The city straddles the Bosphorus strait, and lies in both Europe and Asia, with a population of over 15 million residents, comprising 19% of the population of Turkey. Istanbul is the most populous city in Europe, and the world’s fifteenth-largest city.
Turkey . . . is a country straddling Southeastern Europe and Western Asia. It shares borders with Greece and Bulgaria to the northwest; the Black Sea to the north; Georgia to the northeast; Armenia, Azerbaijan, and Iran to the east; Iraq to the southeast; Syria and the Mediterranean Sea to the south; and the Aegean Sea to the west. Istanbul, the largest city, is the financial centre, and Ankara is the capital. Turks form the vast majority of the nation’s population, and Kurds are the largest minority.
