Hey folks, i just want to mention that over 95% of Ethiopian runners are from Oromo ethnic group who make up half of the Ethiopian population. Here is an excerpt why we don't hear so much about the Oromo people:
"The Oromo were colonised during the last quarter of the nineteenth century by a black African nation - Abyssinia - with the help of the European colonial powers of the day. During the same period, of course, the Somalis, Kenyans, Sudanese and others were colonised by European powers. The fact that the Oromo were colonised by black African nation makes their case quite special.
During the process of colonisation, between 1870 and 1900, the Oromo population was reduced from ten to five millions. This period coincides with the occupation of Oromo land by the Abyssinian emperors Yohannes and Menilek. After colonisation, these emperors and their successors continued to treat Oromo with utmost cruelty. Many were killed by the colonial army and settlers, others died of famine and epidemics of various diseases or were sold off as slaves".
