	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.

	A military coup in 1963 replaced an elected government, and another coup in 1967 saw Gnassingbé Eyadéma assume the presidency, maintaining a one-party state until 1991, when under political pressure, opposition parties were legalised. Eyadéma remained in power until he died in 2005, and amidst further unrest was replaced by his son, who has won elections since. Anti-government protests that began in August 2017 have faced government suppression.

The Department of Water Resources, which sits within the Ministry of Water, is responsible for groundwater monitoring. However, there are currently no national groundwater level or groundwater quality monitoring programmes.

			A project called the Programme to Support Vulnerable Populations (PAPV in French) has been surveying rural water boreholes and rehabilitating non-functional boreholes. In 2017, more than 1500 water boreholes were rehabilitated, and a survey in 2019 identified another 1639 boreholes to be rehabilitated, which will also now be monitored to identify any future failures. This was reported on in an [https://www.afrik21.africa/en/togo-1639-boreholes-to-be-restored-monitored-and-repaired-on-site/ online article].
