Various elements added to the continuous impoverishment and decrease of the Assume realm. The Arab venture into Northern Africa remove the realm's admittance to the Red-Sea stream (and to the business sectors which could be reached through it and on which an enormous piece of the realm's thriving had been based). There is additionally proof to propose that a portion of the realm's normal assets, like gold and ivory, had been exhausted. Almost now is thought about this period of Ethiopian history and researchers even differ on the dates of its start and end.
The political focus of Ethiopia appears to have continuously moved toward the southern and eastern pieces of the Tigray area (the northernmost of the nine locales of Ethiopia) in the Post-Aksumite period. A couple of houses of worship around there have been likely ascribed to this period, however ensuing variations joined with the powerlessness to get consents to direct archeological studies make dating troublesome. It appears to be likely that houses of worship kept on being worked just as (cut) out of rock. A gathering of funerary hypogea (underground loads) in the Hawken plain (in northern Ethiopia) may have been changed into places of worship during the post-Aksumite period. This could be the situation for temples, for example, Abreha-we-Atsbeha (beneath) and Thermos Munro (the artworks in these chapels most likely date from a later period). As indicated by nearby oral customs, few iron crosses date to the Assume or Post-Aksumite periods, yet the shortfall of solid dating strategies and the way that such crosses were delivered at any rate until the sixteenth century, makes it very hard to check these cases.
