Why is the Arab region called the Middle East? What is the standard?

14 and 15 centuries, the capitalist relations of production first sprouted in Europe. Some countries from the Atlantic coast to the North Sea coast of Europe, such as Portugal, Spain, the Netherlands, Britain and France, urgently demand to expand their colonies and plunder wealth, and the rich East is their primary goal. In the sixteenth and seventeenth centuries, they took their own western Europe as the center, and according to their geographical knowledge and habits at that time and their distance from western Europe, they called each part of the general "East" Far East, Middle East and Near East respectively. However, the division of these areas has no clear scope and boundaries. The term "Far East" generally refers to the eastern part of Asia far away from Western Europe, mainly including China, Japan, North Korea and the Pacific coast of the Soviet Union, and sometimes Southeast Asian countries in the Far East. The term "Middle East" is widely used, but its scope and boundary are also very uncertain. In the past, some only referred to Iran and Afghanistan, but now they usually refer to areas mainly in West Asia (but generally excluding Afghanistan), which are located at the junction of Europe, Asia and Africa. At present, there are roughly two views on the geographical scope of the Middle East. In a narrow sense, the Middle East includes all West Asian countries and regions except Afghanistan, namely Iran, Turkey, Cyprus, Syria, Iraq, Lebanon, Palestine, Israel, Jordan, Saudi Arabia, Arab Yemen, Democratic Yemen, Oman, United Arab Emirates, Kuwait, Qatar, Bahrain and Egypt in Africa, with a total of 18 countries and regions; The Middle East in a broad sense, in addition to the above-mentioned countries and regions, plus Libya, Tunisia, Algeria, Morocco, Sudan in North Africa, and even Ethiopia, Belgium and Somalia in East Africa, is also included in the Middle East in a broad sense. Therefore, the geographical scope of the Middle East has been greatly expanded compared with the original concept in history. In the past, the term "Near East" mainly referred to Balkan countries in Europe (Yugoslavia, Albania, Greece, Bulgaria and Romania) and Mediterranean countries and regions in Asia (Turkey, Syria, Lebanon, Palestine, Israel, Jordan, etc.). ) and Cyprus, an island country in the eastern Mediterranean, including Egypt and Libya in North Africa. They have close ties with western Europe. After the First World War, Balkan countries were generally not called Near East countries, but included in the scope of "Southeast Europe" or "Southern Europe". At present, the word "Near East" is not commonly used in the world, but because the Near East and the Middle East have common characteristics in the world political and economic struggle, there is no strict boundary between them, so people often call it "Middle East", and its geographical scope is roughly equivalent to the narrow Middle East mentioned above, plus Balkan countries and Libya. In fact, the most widely used word is "Middle East". Because the residents of most countries in the Middle East belong to the Arab nation and believe in Islam, "Middle East" is often closely linked with "Arab countries" and "Islamic countries". This is the explanation I saw, hehe.
