The obvious choice is South Africa. Interesting choices would be Egypt, Ethiopia, or Liberia. All are difficult, but probably not impossible.
Could happen if the German-educated Gebre-Hiwot Baykedagn becomes attracted to socialism in Germany but opts to establish an African/Ethiopian "variant" which comes to resemble the writings of Kita Ikki and Benito Mussolini's revolutionary nationalism. This provides the impetus from which Fascist thought in Ethiopia evolves as Gebre-Hiwot's works becomes a subject of interest among the Ethiopian intelligentsia while he becomes a prominent advisor to the Ethiopian government when Haile Selassie takes power in 1913. As an advisor to HS, Gebre-Hiwot's attempts to convince the Atse to emulate Japanese modernization prove successful with the establishment of Japanese-Ethiopian relations in 1915-16 as Japanese advisors arrive in Ethiopia to assist with Ethiopian modernization while young Ethiopian students arrive in Japan to receive an education.
In Tokyo, Ethiopian intellectuals read Kita Ikki's
The Theory of Japan's National Polity and Pure Socialism and
An Outline Plan for the Reorganization of Japan where parallels are drawn with Gebre-Hiwot's own literature as they add upon the latter's writings with inspiration from these works. Ethiopian students in Italy during the 1920s do the same with Fascist literature as the tenets of Fascism are also applied to Gebre-Hiwot's works, allowing for the creation of a genuinely Fascist Ethiopian ideology under one man (someone like Tekle Wolde Hawariat) in the late 1920s. Under the influence of TTL's Ethio-Fascism, Haile Selassie begins to see it as a means of ensuring absolute control over Ethiopia and to hasten Ethiopian modernization as he turns to the world's Fascist countries to provide assistance - this includes Mussolini's Italy and an interested Japan.
By the early 1930s, Haile Selassie is firmly in control of Ethiopia after quietly getting rid of the nobles who oppose his reforms and crushing those who dare revolt against his rule as reforms are implemented in earnest with the backing of the Japanese. Throughout the 1930s, he focuses on instituting Fascism in a top-down fashion that comes to resemble Fascist Italy's process while also taking inspiration from Imperial Japan, Metaxist Greece, Salazar's Portugal and Nazi Germany in Ethiopian modernization. Meanwhile, Italy is attempting to encroach on Ethiopia's sovereignty while planning to displace the significant Japanese influence in East Africa - Ethiopia continues protecting her sovereignty via the growing Imperial Ethiopian Army with Japanese backing.
