English: Between 1946 and 1991, the border between Begemder and Tigray was located on the Tekeze River, as displayed on an atlas map by The Times Atlas of the World (1956). Earlier on, that course of the border had made a relatively short appearance in the time series, around the turn of the 20th Century (Habenicht 1891, Johnston 1893, De Chaurand 1894, Stieler and Lueddecke 1894, Brockhaus 1895, Anon. 1896, Rossetti 1907, Petri and Shokalskago 1909).

The map displays boundaries of political control, which may locally be different from lines of language transition. This map extract is conformably oriented with north up and approx. 450 km wide.
