During the late 1940s and the early 1950s, there were serious negotations going on about the future of the former German colony of Togoland, at the time administerd as two trust territories by the UK and France. In particular the Ewe people, who formed the majority in the southern parts of both British and French Togoland, were strong advocates for the reunification of Togoland. Several petitions were made, mostly from the southern section of British Togoland (pictured above), though some were also filed from the northern section and French Togoland.
According to "The Internationalization of Colonialism: Britain, France, and Black Africa 1939-1956 " by John Kent, in 1951 several Togolese advocacy groups, mostly Ewe, were hosting a conference at the town of Kpalimé in French Togoland to declare their wishes to the UN that the halves of Togoland were to be united into a unified mandate, controlled by the UN itself, with a clear schedule towards decolonization in five years, which would also involve a new referendum on the various parts of Togoland determining whether they wish to join any neighboring states or be part of a unified Togoland.
Meanwhile a concurrent international factfinding mission had its own proposals for the Togoland question. American diplomat Benjamin Gerig suggested that the Gold Coast Colony should be united with both the French and British controlled areas inhabited by the Ewe people. While he is not reported to have said anything about what would happen with the two northern halves, there would be, in my opinion, three reasonable options: a landlocked unified North Togoland, a partition of northern Togoland between Ghana and Benin/Dahomey, and a replication of OTL (independent northern French Togo and northern British Togoland becomes also part of Ghana or a northern state in Ghana).
The main Iraqi diplomat of that mission, Awni Al-Khalidi, instead suggested that French Togoland also be put under British mandate, with future plebiscites determining the exact future of these territories. Britain was reportedly
strongly opposed to this idea.
When ultimately in 1956 a plesbicite was held in British Togoland on the question of whether British Togoland were to be integrated into the future country of Ghana, which became Britain's preferred solution, the results were as follows:
| PRO-INTEGRATION | ANTI-INTEGRATION |
NORTHERN TOGOLAND | 48,793 | 12,614 |
SOUTHERN TOGOLAND | 43,976 | 54,786 |
TOTAL | 92,769 | 67,400 |
Britain chose to interpret this plebiscite to mean that all of British Togoland would join Ghana, but if it had decided to follow the results based on region, then only the northern parts of British Togoland would've joined Ghana, while the southern half likely would have joined (French) Togo or a (purely) Ewe state sooner or later.
EDIT: I changed the wording a bit, mostly in regards to the uncertainty about northern British Togoland in the Gerig proposal, and I also wanted to mention that the 1956 map from
The Times Atlas of the World seems to indicate that the border of northern and southern British Togoland has been shifted northwards compared to the recreation of the 1925 situation shown above. Northern Togoland in 1956 seems to have its border roughly equivalent to the border between the Northern Territories and Ashanti, rather than the border between the Gold Coast Colony and Ashanti (though it also indicates the old border).
