No one said it was kingdoms u fool, they were city statesNot a single historical source or proof what's so ever lol. You don't even understand what your argument entails. Your source says "One route led down to the East African coast from Ethiopia to Somalia." Once again, there is no mention of any ancient Somali kingdom trading with the Romans. The source was literally describing the geographical area that the Romans traded with. Somalia didn't exist until 1960.
The video you presented literally says Far-Side ports were relatively uncivilized. There were no cities or indigenous kingdoms. The natives lived in self-governing tribal kingdoms lol. You literally debunked yourself. You still didn't show me any source that states that ancient Somalis traded with the Romans. You just provide numerous articles and videos that show no concrete proof
