I'll be frank bro, I'm not well researched when it comes to the topic of the Axumite kingdom, I'm just recalling bits & pieces of information I came across of it over the years. I don't have spare time to delve into further research of it either which is why I'm mostly linking wikipediaWell walaal if historical research in the horn of africa is very limited anything we say is conjunction and mere speculation. How can we confidently say that the ezana tablet is not a boast an empty bravado by the axumite king? We need at the very least another outside source to confirm the claim. If anything the descendent of the axumite today are well known for their outrageous claims.
The presence of somali mercenaries is also known by the arabs and you could find reference to it in sirat ibn hashim. That being said the presence of somali mercenaries or berbers as they were called doesn't mean much. There were berber mercenaries in the kinda armies does that mean that kinda also ruled northern somali?
The presences of christians back then is no proof of any axumite rule. Does the presence of islam in somalia means yemeni ruled northern somali? In fact in the case of islam almost the whole of somalia in the 15th century were muslims does that mean that yemen ruled all of somalia? Socotra had orthodox christians community up until the 16th century does that mean axumite ruled socotra? Kerala in india had orthodox christians does that mean axumite ruled southern india?
At the very least the yemeni theory have somethings to go off of such as some letters writing by somalis in the 20th century appears to have a yemeni dialect in them, somalia and yemen follow the shafi' madhab and some somali not only claim to have come from yemen but also a lot of somalis would travel there for seeking knwoledge. Plus somali presence in yemen is well known and very old.
There obviously needs to be more research to determine for sure that Axum governed Somali territories, and with such little information on the history of the horn in general the most we can do is speculate at the moment. I still think that it's likely Axum ruled parts of Somali territory during its peak which isn't anything to be ashamed about, we also ruled them during various periods, and have an illustrious history of own to be proud of.
The only reason I even bothered getting into the topic is because I found the reasoning of the person above to be very cringe. His logic can also easily be turned against Somalis & makes us come off as jealous of other peoples history.there is more proof that the aksumite kingdom wasn’t even a habesha kingdom. I was reading how the nobles and high officials of Aksum lived in massive stone buildings yet the Abyssinians were living in mud huts and tents lmao. Massive civilizational decline does not happen unless some form of population replacement occurs
