The State of Somaliland (former British Somaliland) could have stayed a separate country instead of merging with the Trust Territory of Somaliland (former Italian Somaliland) to create Somalia.
Former British Somaliland is an autonomous region calling themselves the Republic of Somaliland and is independent in every way except international recognition. The reason they're not recognized internationally is that it would give legitimacy to the extremist government that controls the former Italian Somaliland.
