World War I: The German colony of Togoland surrenders to French and British forces after a 20-day campaign. Togoland is the first German colony to fall to Allied hands in World War I.

World War I or the First World War, also known as the Great War, was a global conflict between two coalitions: the Allies and the Central Powers. Main areas of conflict included Europe and the Middle East, as well as parts of Africa and the Asia-Pacific. There were important developments in weaponry including tanks, aircraft, artillery, machine guns, and chemical weapons. One of the deadliest conflicts in history, it resulted in an estimated 30 million military casualties, plus another 8 million civilian deaths from war-related causes and genocide. The movement of large numbers of people was a major factor in the deadly Spanish flu pandemic.

A colony is a territory subject to a form of foreign rule, which rules the territory and its indigenous peoples separated from the foreign rulers, the colonizer, and their metropole. This separated rule was often organized into colonial empires, with their metropoles at their centers, making colonies neither annexed or even integrated territories, nor client states. Particularly new imperialism and its colonialism advanced this separated rule and its lasting coloniality. Colonies were most often set up and colonized for exploitation and possibly settlement by colonists.

Togoland, officially the Togoland Protectorate, was a protectorate of the German Empire in West Africa from 1884 to 1914, encompassing what is now the nation of Togo and most of what is now the Volta Region of Ghana, approximately 90,400 km² in size. During the period known as the "Scramble for Africa", the colony was established in 1884 and was gradually extended inland.

The Togoland campaign was a French and British invasion of the German colony of Togoland in West Africa, which began the West African campaign of the First World War. German colonial forces withdrew from the capital Lomé and the coastal province to fight delaying actions on the route north to Kamina, where the Kamina Funkstation linked the government in Berlin to Togoland, the Atlantic and South America.
