Afro-Eurasia
Three continents combined
Afro-Eurasia is the combined landmass of Africa, Europe, and Asia—the largest continuous land area on Earth, connected at the Sinai Peninsula and historically at various land bridges.
The term appears mainly in geography and world history discussions that treat these three continents as a single interconnected zone of human civilization and migration: Afro-Eurasian trade networks predated European colonialism by millennia.
