Macaronesia

Macaronesia (Portuguese: Macaronésia; Spanish: Macaronesia) is a collection of four volcanic archipelagos in the North Atlantic Ocean, off the coast of North Africa and Europe. Each archipelago is made up of a number of Atlantic oceanic islands, which were formed by seamounts on the ocean floor whose peaks have risen above the ocean's surface.

Each of the archipelagos is a distinct political entity: the Azores and Madeira are autonomous regions of Portugal, the Canary Islands is an autonomous community of Spain, while Cape Verde, a former Portuguese colony, is a sovereign state and member of the United Nations. Politically, the islands belonging to Portugal and Spain are parts of the European Union, while Cape Verde is a member of the African Union. Geologically, most of Macaronesia is part of the African tectonic plate. The Azores are located in the triple junction between the Eurasian, African, and North American plates.

In one biogeographical system, the Cape Verde archipelago is in the Afrotropical realm while the other three archipelagos are in the Palearctic realm. According to the European Environment Agency, the three archipelagos within the European Union constitute a unique bioregion, known as the Macaronesian Biogeographic Region. The World Geographical Scheme for Recording Plant Distributions places the whole of Macaronesia in its botanical continent of Africa.

In 2022, Macaronesia had an estimated combined population of 3,222,054 people; 2,172,944 (67%) in the Canary Islands, 561,901 (17%) in Cape Verde, 250,769 (8%) in Madeira, and 236,440 (7%) in the Azores.

The name Macaronesia was originally used by Ancient Greek geographers to refer to any islands west of the Strait of Gibraltar. It is derived from the Greek words meaning 'islands of the fortunate' (μακάρων νῆσοι, makárōn nēsoi). The term fell out of use until it was revived in 1917 with its current meaning.

The name is occasionally misspelled "Macronesia"[citation needed] in false analogy with Micronesia, an unrelated group of archipelagos in the Pacific Ocean whose name is also derived from Greek.

Macaronesia consists of four main archipelagos. In alphabetical order, these are:
