Asia Asia is the largest and most populous landmass on Earth, spanning diverse climates, peoples, and political entities. It contains major river systems, mountain ranges, deserts, archipelagos, and megacities that shape global trade, technology, and culture. The region hosts ancient civilizations, modern states, international organizations, and transcontinental infrastructures that link Europe, Africa, and Oceania.

Etymology and Definitions

The term "Asia" derives from classical usage by Herodotus and Homer and was later codified in works by Strabo and Ptolemy. Definitions vary among cartographers such as Claudius Ptolemy and modern entities like the United Nations and the International Hydrographic Organization. Geographic delimitations invoke features like the Ural Mountains, Caspian Sea, Caucasus Mountains, and the Suez Canal; legal and political boundaries reference treaties such as the Treaty of Lausanne and accords involving the Ottoman Empire and successor states.
