Eritrea was created in 1993, half of Eritrea was under Adal for more than a few decades, and we have shared history with the now wild Canfar and Saho people.How somalis eritreans and ethiopains were one?
Ethiopia is also a recently created modern times state, its imperial days ended with Italian colonization in the 1930s.
What you need to differentiate is Abyssinia or Habeshistan from Eritrea and Ethiopia, I never said we were one with Abyssinia, its infact much smaller than Adal historically and thats excluding the southern muslim provinces of Adal and most of present day Somalia/NDF and DDS
We were however one with almost the entirety of cushetic speakers and have shared history, language, and religion, even pre-islamic history.
