The tropics are the regions of Earth surrounding the Equator, where the sun may shine directly overhead. This contrasts with the temperate or polar regions of Earth, where the Sun can never be directly overhead. This is because of Earth's axial tilt; the width of the tropics is twice the tilt. The tropics are also referred to as the tropical zone and the torrid zone.
The Tropic of Capricorn is the circle of latitude that contains the subsolar point at the December solstice. It is thus the southernmost latitude where the Sun can be seen directly overhead. It also reaches 90 degrees below the horizon at solar midnight on the June Solstice. Its northern equivalent is the Tropic of Cancer.

The subtropical zones or subtropics are geographical and climate zones immediately to the north and south of the tropics. Geographically part of the temperate zones of both hemispheres, they cover the middle latitudes from 23°26′09.8″ (or 23.43605°) to approximately 35° north and south. The horse latitudes lie within this range.

A tropical marine climate is a tropical climate that is primarily influenced by the ocean. It is usually experienced by islands and coastal areas 10° to 20° north and south of the equator. There are two main seasons in a tropical marine climate: the wet season and the dry season. The annual rainfall is 1000 to over 1500 mm. The temperature ranges from 20 to 35 °C. Under the Köppen climate classification, a "tropical marine climate" would fall under Af or Am, tropical rainforest or tropical monsoon climate. The trade winds blow all year round and are moist, as they pass over warm seas. These climatic conditions are found, for example, across the Caribbean, the eastern coasts of Brazil, Madagascar and Queensland; and many islands in tropical waters.

Stephen Adebanji Akintoye, also known as S. Banji Akintoye, is a Nigerian-born academic, historian and writer. He attended Christ's School Ado Ekiti, Nigeria from 1951–1955, and studied history at the University College, Ibadan (1956–1961), and doctoral studies from 1963-1966 at the University of Ibadan, where he was awarded a PhD in History in 1966. He taught at the History Department at Obafemi Awolowo University, Ile-Ife, Nigeria, where he became a professor and Director of the Institute of African Studies from 1974-1977. He has also taught African History in universities in the United States including the University of South Florida, Tampa, Florida; Montgomery County Community College, PA, and Eastern University, St. Davids, Pennsylvania. Akintoye has written four books, chapters in many joint books, and several articles in scholarly journals. He took a leading part for some time in the politics of Nigeria and served on the Nigerian Senate from 1979–1983 during the Second Republic. He currently lives in Cotonoue, Benin Republic. Akintoye is one of the current leading scholars on the history of the Yoruba people. His most recent work, A History of the Yoruba People, draws on decades of new findings and thinking on Yoruba studies that challenges some previously dominant notions about the origins of the Yoruba. This work dispels the Middle Eastern and Arabia origins propounded by such scholars as the late Samuel Johnson (1846–1901) and also gave prominence to the works on the Pre-Oduduwa Period by Ulli Beier among others. Akintoye also gave prominence to the role of Ilé-Ifè over that of Oyo. A reviewer, Wale Adebanwi, notes: "...this book directly contests and shifts th e focus of Yoruba history away from what many have called the Oyo-centric account of Samuel Johnson... Where Johnson avoids the creation myth that positions Ife as the sacred locus of Oduduwa's original descent and the orirun (creation-source), Akintoye, justifiably, restores Ile-Ife to its proper place as "ibi ojumo ti mon wa'ye" ..."
