Eurasia


Eurasia is the largest continental area on Earth, comprising all of Europe and Asia. According to some models of the world, physio-graphically, Eurasia is a single continent. The concept of Europe and Asia as distinct continents dates back to antiquity, but their borders have historically been subject to change. For example, the ancient Greeks originally included Africa in Asia but classified Europe as separate land. Eurasia is connected to Africa at the Suez Canal, and the two are sometimes combined to describe the largest contiguous landmass on Earth, Afro-Eurasia.

History

Eurasia has been the host of many ancient civilizations, including those based in Mesopotamia, Egypt, the Indus Valley and China. In the Axial Age, a continuous belt of civilizations stretched through the Eurasian subtropical zone from the Atlantic to the Pacific. This belt became the mainstream of world history for two millennia.
New connections emerged between the subregions of Eurasia from the Age of Discovery onwards, with the Iberians discovering new maritime routes in the 1490s, and the 1869 completion of the Suez Canal having paved the way for direct passage through the Indo-Mediterranean and the wave of Western European "New Imperialism" that dominated Africa and Asia until the mid-20th century. The communist presence in Eurasia then dominated much of the continent until the end of the Cold War in 1991.

Geography

Primarily in the Northern and Eastern Hemispheres, Eurasia spans from Iceland and the Iberian Peninsula in the west to the Russian Far East, and from the Russian Far North to Maritime Southeast Asia in the south, but other specific geographical limits of Eurasia states that the southern limit is in the Weber's line. Eurasia is bordered by Africa to the southwest, the Atlantic Ocean to the west, the Arctic Ocean to the north, the Pacific Ocean to the east, and the Indo-Mediterranean to the south. The division between Europe and Asia as two continents is a historical social construct, as neither fits the usual definition; thus, in some parts of the world, Eurasia is recognized as the largest of the six, five, or four continents on Earth.
Eurasia covers around, or around 36.2% of the Earth's total land area. The landmass contains well over 5 billion people, equating to approximately 70% of the human population. Humans first settled in Eurasia from Africa 125,000 years ago.
The contains many peninsulas, including the Arabian Peninsula, Korean Peninsula, Indian subcontinent, Anatolia Peninsula, Kamchatka Peninsula, and the Italian Peninsula.
Due to its vast size and differences in latitude, Eurasia exhibits all types of climates under the Köppen classification, including the harshest types of hot and cold temperatures, high and low precipitation, and various types of ecosystems.
Eurasia is considered a supercontinent, part of the supercontinent of Afro-Eurasia or simply a continent in its own right. In plate tectonics, the Eurasian Plate includes Europe and most of Asia but not the Indian subcontinent, the Arabian Peninsula or the area of the Russian Far East east of the Chersky Range.
From the point of view of history and culture, Eurasia can be loosely subdivided into Western Eurasia and Eastern Eurasia.

Geology

In geology, Eurasia is often considered as a single rigid mega block, but this is debated. Eurasia formed between 375 and 325 million years ago with the merging of Siberia, Kazakhstania, and Baltica, which was joined to Laurentia, to form Euramerica.

Rivers

This is a list of the longest rivers in Eurasia. Included are all rivers over.

Mountains

All of the 100 highest mountains on Earth are in Eurasia, in the Himalaya, Karakoram, Hindu Kush, Pamir, Hengduan, and Tian Shan mountain ranges, and all peaks above 7,000 metres are in these ranges and the Transhimalaya. Other high ranges include the Kunlun, Hindu Raj, and Caucasus Mountains. The Alpide belt stretches 15,000 km across southern Eurasia, from Java in Maritime Southeast Asia to the Iberian Peninsula in Western Europe, including the ranges of the Himalayas, Karakoram, Hindu Kush, Alborz, Caucasus, and the Alps. Long ranges outside the Alpide Belt include the East Siberian, Altai, Scandinavian, Qinling, Western Ghats, Vindhya, Byrranga, and Annamite Ranges.

Islands

The largest Eurasian islands by area are Borneo, Sumatra, Honshu, Great Britain, Sulawesi, Java, Luzon, Iceland, Mindanao, Ireland, Hokkaido, Sakhalin, and Sri Lanka. The five most-populated islands in the world are Java, Honshu, Great Britain, Luzon, and Sumatra. Other Eurasian islands with large populations include Mindanao, Taiwan, Salsette, Borneo, Sri Lanka, Sulawesi, Kyushu, and Hainan. The most densely populated islands in Eurasia are Caubian Gamay Island, Ap Lei Chau, and Navotas Island. In the Arctic Ocean, Severny Island, Nordaustlandet, October Revolution Island, and Bolshevik Island are Eurasia's largest uninhabited islands, and Kotelny Island, Alexandra Land, and Spitsbergen are the least-densely populated.

Russian geopolitical ideology

Originally, "Eurasia" is a geographical notion: in this sense, it is simply the biggest continent; the combined landmass of Europe and Asia. However, geopolitically, the word has several meanings, reflecting specific geopolitical interests. "Eurasia" is one of the most important geopolitical concepts and it figures prominently in the commentaries on the ideas of Halford Mackinder. As Zbigniew Brzezinski observed on Eurasia:
The Russian "Eurasianism" corresponded initially more or less to the land area of Imperial Russia in 1914, including parts of Eastern Europe. One of Russia's main geopolitical interests lies in ever closer integration with those countries that it considers part of "Eurasia."
The term Eurasia gained geopolitical reputation as one of the three super-states in 1984, George Orwell's novel where constant surveillance and propaganda are strategic elements of the heterogeneous dispositif such metapolitical constructs used to control and exercise power.

Regional organizations and alliances

Across Eurasia, several single markets have emerged, including the Eurasian Economic Space, European Single Market, ASEAN Economic Community, and the Gulf Cooperation Council. There are also several international organizations and initiatives which seek to promote integration throughout Eurasia, including:

Russia-EU Common Spaces

The Greater Eurasian Partnership is an initiative of Russian President Vladimir Putin, put forward in his address to the Federal Assembly in 2015 with the aim of forming a broad integration framework on the Eurasian continent, as indicated by the Russian Foreign Ministry. In Perm on 29 May 2025, Sergey Lavrov stated at the Eurasian International Socio-Political Hearings on the Formation of an Architecture of an Equal and Indivisible System of Security and Cooperation in the Eurasian Space in 2025 that "the Greater Eurasian Partnership is not limited to economics, trade, transport and logistics alone. It is the material basis for another Russian initiative - the initiative to form a Eurasian security architecture, which Putin put forward in his speech at the Russian Foreign Ministry on 14 June 2024. In Africa, there is a pan-continental organization, the African Union, in Latin America - CELAC, but in Eurasia there is no such pan-continental association yet."
