In historical times, present-day Togo lay between the powerful kingdoms of Ashanti and Dahomey. From the 11th to 16th centuries, various peoples migrated there from neighbouring regions, including Ewe people from the area of present-day Nigeria, who comprise the majority ethnic group today. European slave trading posts were established on the coast in the 16th century. In the late 19th century German claimed control over what was called Togoland, and after World War I this was claimed and divided by Britain and France. British Togoland voted to join the Gold Coast, becoming independent as part of the nation of Ghana in 1957. French Togoland remained separate and became independent as the Togolose Republic in 1960.

Togo is a narrow country extending from the border with Burkina Faso in the north to the Atlantic Ocean (Gulf of Guinea) in the south. The north of the country is dominated by savannah while the coast is generally a low lying plain with numerous lagoons and marshes. The Togo Mountains extend from the south west border with Ghana to the north east border with Benin, reaching a maximum elevation of over 900 m.

The climate of Togo is classified as Tropical Savannah. Annual average temperatures are slightly higher in the north and lower in the south. They also decrease with altitude in the mountainous regions. Precipitation is generally lower in the north and higher in the south but also increases slightly over the mountainous regions.
