Tigray Region
Tigray Region (, "kilil Tigrāy;" Official name: , "Bəh̩erawi Kəllelawi Mängəśti Təgray", "Tigray National Regional State") is the northernmost of the nine regions ("kililat") of Ethiopia. Tigray is the homeland of the Tigrayan, Irob and Kunama peoples. Tigray is also known as Region 1 according to the federal constitution. Its capital and largest city is Mekelle. Tigray is the 6th largest by area, the 5th most populous, and the 5th most densely populated of the 9 Regional States.
Tigray Province
Tigray went through numerous administrative changes in the course of its history. In 1991 Tigray was radically reshaped. During the reign of Haile Selassie I and also the following Derg period, Tigray did not yet encompass Welqayt (until 1991 having been part of Begemder), while Enderta in eastern Tigray extended over large Afar areas including the salt plains, which were given to Afar "kəlləl". Still in the 1930s the regions south of Enderta, i.e. Wajjarat and Angot, formed the separate governorate called "Southern Tigray". Modern Tigray is the result of a merger of diverse historical northern provinces (with Tigrinya and Agaw speakers), which were often independent from each other.
Today's unity of Tigrayan territories south of the Mereb river is a rather modern phenomenon. Most northern provinces were ruled by their own governors, often descending from local dynasties and preserving a high degree of autonomy within the empire, e.g., in legal and judicial issues, taxation etc. Only rarely these territories were unified under one ruler.
