Not really Zanj was the name they had for Bantu population from in the Swahili States in south. It was an Ethnonym for ''Bantus''
This is one of the mistakes many Western Oriental writers like Ali Jimale /Ali Mukhtar make when they speak of Mogadishu they tend to lump it with the Swahili world , despite the Arab world were direct in distinguishing us from them. So this is an assertion they are copying and pasting into Somali historiography.
Plus Land of the Barbars was an earlier Pre-Islamic denote for Somalis used by the Greeks and Ancient Egyptians, which was then afterwards carried by the Arabs ,so it existed way before there was any mention of the word Zanj.
There is no actua sources mentioning Mogadishu being part of Bilad Al Zanj there are only mentions of Southern Somalia(Including Mogadishu) being part Bilad Al Barbar and inhabited by Barbars.
For example one of the sources include the twelfth century Syrian historian Yaqut al-Hamawi, who explained that the inhabitants of Mogadishu were dark-skinned Berbers (the ancestors of the Somali). From J. D. Fage, Roland Oliver, Roland Anthony Oliver, The Cambridge History of Africa, (Cambridge University Press: 1977), p. 190.:
And the Moroccan traveler Ibn Battuta, who visited the city in 1331 and made sure to distinguish between the inhabitants of the Bilad al-Barbar ("The Land of the Berbers", which was the medieval Arabic name for the Somali coast) and the Bilad al-Zanj ("The Land of the Zanj, which was the old Arabic name for the Swahili coast to the south of it). From The Rise and Fall of Swahili States by Chapurukha Makokha Kusimba, p.58:

Saldanadda Muqdisho (which was a prosperous trading empire) existed before it eventually became part of Dawladii Ajuuran. Do you have proof that the expansion south was so recent?Don't forget that Somalis migrated from Barbara/the North. Like the Ajuran. They never settled in the south which was at that time mostly empty or had Eastern Cushitic people. On the coast, the Parthian empire had colonies to export minerals and slaves from. Somalis conquered the South not before the 13th century. The first ones to expand south was Ajuran
There is a clan named "Harla Koombe"-brother of Geri, Cabdi and Harti Koombe. Similar name or are they connected? Somali history is so fascinating, too bad our history is mostly oral and not written down.
