Wikipedia Trail: From Greece to

1. Greece: Greece, officially the Hellenic Republic (Greek: Ελληνική Δημοκρατία), historically also known as Hellas, is a country located in Southern and Southeast Europe, with a population of approximately 11 million as of 2016. Athens is the nation's capital and largest city, followed by Thessaloniki.

Greece is located at the crossroads of Europe, Asia, and Africa. Situated on the southern tip of the Balkan Peninsula, it shares land borders with Albania to the northwest, the Republic of Macedonia and Bulgaria to the north, and Turkey to the northeast.

2. Turkey: Turkey is a transcontinentalcountry located mainly in Western Asia, with a smaller portion on the Balkan peninsula in Southeast Europe. East Thrace, located in Europe, is separated from Anatolia by the Sea of Marmara, the Bosphorous strait and the Dardanelles (collectively called the Turkish Straits).

3. Western Asia: Western Asia, West Asia, Southwestern Asia or Southwest Asia is the westernmost subregion of Asia. The concept is in limited use, as it significantly overlaps with the Middle East (or the Near East), the main difference usually being the exclusion of the majority of Egypt (which would be counted as part of North Africa) and the inclusion of the Caucasus. 

4. Middle East: The Middle East is a transcontinental region centered on Western Asia, Turkey (both Asian and European), and Egypt (which is mostly in North Africa). Saudi Arabia is geographically the largest Middle Eastern nation while Bahrain is the smallest. The corresponding adjective is Middle Eastern and the derived noun is Middle Easterner.
