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 Near East), the main difference being the exclusion of Egypt (which would be counted as part of North Africa).

The term is sometimes used for the purposes of grouping countries in statistics. The total population of Western Asia is estimated at about 300 million as of 2015.

In an unrelated context, the term is also used in ancient history and archaeology to divide the Fertile Crescent into the "Asiatic" or "Western Asian" cultures as opposed to Ancient Egypt.

Definitions

As a geographic concept, "Western Asia" includes the Levant, Mesopotamia, the Arabian peninsula, Anatolia, Iran, Armenian Highlands and South Caucasus. The Sinai Peninsula belongs to Western Asia, making Egypt a transcontinental country.

However, the term "Western Asia" is mostly used as a convenient division of contemporary sovereign states into a manageable number of world regions for statistical purposes; it is sometimes used instead of the more geopolitical term "Middle East", for example by the United Nations Statistics Division (UNSD) statistics office or the Government of Canada.

Asia

Asia (ⁱ/ˈeɪʒə/ or /ˈeɪʃə/) is the Earth's largest and most populous continent, located primarily in the eastern and northern hemispheres. Asia covers an area of 44,579,000 square kilometers, about 30% of Earth's total land area and 8.7% of the Earth's total surface area. It has historically been home to the world's first modern civilizations and has always hosted the bulk of the planet's human population. Asia is notable for not only overall large size and population, but unusually dense and large settlements as well as vast barely populated regions within the continent of 4.4 billion people. The boundaries of Asia are traditionally determined as that of Eurasia, as there is no significant geographical separation between Asia and Europe. The most commonly accepted boundaries place Asia to the east of the Suez Canal, the Ural River, and the Ural Mountains, and south of the Caucasus Mountains and the Caspian and Black Seas. It is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean and on the north by the Arctic Ocean.

History

Early history

Southwest Airlines began with the March 15, 1967, incorporation of Air Southwest Co. by Rollin King and Herb Kelleher to fly within the state of Texas.

North Africa

North Africa or Northern Africa is the northernmost region of Africa. Geopolitically, the United Nations definition of Northern Africa includes seven countries and territories; Algeria, Egypt, Libya, Morocco, Sudan, Tunisia, and Western Sahara. Algeria, Morocco, Tunisia, Libya, often Mauritania and Western Sahara form the Maghreb, while Egypt and Sudan comprise the Nile Valley (so named after the Nile River, which has two tributaries; the White Nile and Blue Nile). Egypt is a transcontinental country because of the Sinai Peninsula, which geographically lies in West Asia. North Africa also includes a number of Spanish possessions (Ceuta and Melilla and tiny Spanish islets off the coast of Morocco). The Canary Islands and the Portuguese Madeira Islands, in the North Atlantic Ocean northwest of the African mainland, are sometimes included in considerations of the region.

The distinction between North Africa and much of Sub-Saharan Africa is historically and ecologically significant because of the effective barrier created by the Sahara Desert for much of modern history. From 3500 BC, following the abrupt desertification of the Sahara due to gradual changes in the Earth's orbit, this barrier has culturally separated the North from the rest of the continent. As the seafaring civilizations of the Phoenicians, Greeks, Romans, Muslims and others facilitated communication and migration across the Mediterranean Sea, the cultures of North Africa became much more closely tied to Southwestern Asia and Europe than Sub-Saharan Africa. The Islamic influence in the area is also significant, and North Africa is a major part of the Islamic world.
