Question: Is the first proposer of the existence of an Abydos Dynasty still alive today? Passage 1:The existence of an Abydos Dynasty was first proposed by Detlef Franke and later elaborated on by Kim Ryholt in 1997. Ryholt observes that two attested kings of this period, Wepwawetemsaf (Wepwawet is his protection) and Pantjeny (He of Thinis), bore names in connection with Abydos: Wepwawet being an important Abydene god and Thinis being a prominent city, located a few miles north of Abydos. Additionally, Wepwawetemsaf, Pantjeny and Snaaib, another king of the period, are each known from single stelae discovered in Abydos, which could be a sign that this was their seat of power. Finally, Ryholt argues that the existence of an Abydos Dynasty would explain 16 entries of the Turin canon at the end of the 16th Dynasty. The Abydos Dynasty may have come into existence in the time lapse between the fall of the 13th Dynasty with the conquest of Memphis by the Hyksos and the southward progression of the Hyksos to Thebes.
 Passage 2:The Derg overthrew the Ethiopian Empire and Emperor Haile Selassie in a coup d'état on 12 September 1974, establishing Ethiopia as a Marxist-Leninist communist state with itself as a military junta and provisional government. Various left-wing, ethnic, and anti-communist opposition groups supported by the United States began armed resistance to the Soviet-backed Derg, in addition to the Eritrean separatists already fighting in the Eritrean War of Independence. The Derg used military campaigns and the Qey Shibir (Ethiopian Red Terror) to repress the rebels. By the mid-1980s, various issues such as the 1983–1985 famine, economic decline and other after-effects of Derg policies ravaged Ethiopia, increasing popular support for the rebels. The Derg dissolved itself in 1987, establishing the People's Democratic Republic of Ethiopia (PDRE) under the Workers' Party of Ethiopia (WEP) in an attempt to maintain its rule. The Soviet Union ended its support for the PDRE in the late-1980s and the government was overwhelmed by the increasingly victorious rebel groups. In May 1991, the PDRE was defeated in Eritrea and President Mengistu Haile Mariam fled the country. The Ethiopian Civil War ended on 4 June 1991 when the Ethiopian People's Revolutionary Democratic Front (EPRDF), a coalition of left-wing ethnic rebel groups, entered the capital Addis Ababa and overthrew the WEP. The PDRE was dissolved and replaced with the Tigray People's Liberation Front-led Transitional Government of Ethiopia.
