Many many documents in Arabia attest to Axumite conquest of Yemen and parts of Saudi Arabia, a Roman traveller also attests to Axumites having control over parts of Sudan theres no reason to believe this is an "empty bravado" Somalia was no way near as developed or relevant as South Arabia or Kush(at this point in time), 2 regions which have both been confirmed by non Axumite sources to have be conquered by Axumites, so why would they lie about conquering Somalia?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.
Its funny because if there were texts in Somalia that said that they conquered Habeshas/Axumites and there was no non-Somali sources to prove it, no one here would care and everyone would treat it as gospel and scream from the rooftops that Somalis conquered Axum.
