We only know the invasion, destruction and occcupation of the Sultanate of Shewa by kings of the defunct Solomonic Dynasty but we have no records of how badly the persons of Argoba were mistreated, how their social norms and cultures were destroyed, and how their lands were plundered and given to Amara settlers.
Their country stretch included Metehara, Ankober, Shewa Robit bordered Harla in the east and Afar in the north.
They are out of the national oppression languages of TPLF, OLF, SNLF. Could it be because Amara thugs claim Argobas to be a version of themselves by an unknown measurement yard stick. Obviously, simply speaking a semitic language doesn't constitute the same tribe. Example, Tigrey and Amara.
Also, none of the above organizations mention Gurage as a conquered and colonized subject of the feudal empire they fought against for freedom for themselves. Could be due to some Tenkirs. Tenkir, Chaha, was a PhD in Geography(BIH). I told him I was a brorher. He replied he was Amara. I told him I did not know Amara with a name, Tenkir, other than Gurage. He insisted he was an Amara.
