Tigray Province
The oldest inscriptions and texts referring to the population of the Aksumite kingdom and its neighbors do not know the term Tigray yet; they show an ethnic diversity, which has partially disappeared today. A variant of the term Tigray, first appears in a 10th-century gloss to "Cosmas Indicopleustes", i.e. after the Aksumite period; according to this source important groups of the region were the "" and the "" (i.e. the Agʿazi), the latter being the Aksumites. The toponym Tigray is probably originally ethnic, the "" then meant "the tribes near Adulis". They correspond to the Tigre groups living in the same area today; however, a historical identity between today's sub-groups and the 10th century groups cannot be supposed, as this could not explain the existence of the toponym "Tigray" for the Aksum-Adwa area. It should be concluded that Tigray groups lived along the main route between Aksum and the coast, and later separated, both ethnically and linguistically. There is no indication that the term Tigray could be explained through Ge'ez ("subdue"), with the meaning "the submitted" (in supposed contrast to the "free" Agaziyan linked with the rulers of Aksum), as this could not explain why the most important province took the name Tigray. The term might even not be Ethiosemetic and predate the Sabaen presence in Ethiopia. It is not excluded that the term ("Tekaru") from a list of southern peoples and countries allegedly subdued by Pharaonic Egypt in the 15th century BC may already be linked with the term Tigray; in this case it should mean a region within or in the vicinity of Punt.
Tigray Region
In the 14th century the Tigrinya-speaking lands (Tigray-Mereb Melash) were divided into two provinces, separated by the Mereb River by the newly enthroned Amhara Emperors. The governor of the northern province received the title Bahre Negash (Ruler of the sea), whereas the governor of the southern province was given the title of Tigray Mekonen (Lord of Tigray). The Portuguese Jesuit, Emanuele Baradas' work titled "Do reino de Tigr" and written in 1633-34 states that the "reino de Tigr" extended from Hamasien to Temben, from the borders of Dankel to the Adwa mountain. He also stated that Tigray-Mereb Melash was divided into twenty-four smaller political units (principalities), twelve of which were located south of the Mereb and governed by the Tigray Mekonen based in Enderta. The other twelve were located north of the Mereb under the authority of the Bahre Negash, based in the district of Serae.
