Question: How many years had the Emperor Haile Selassie been in power when the Derg overthrew his rule in 1974? Passage 1: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.

 Passage 3:Berkeley Zen Center (BZC), temple name , is a Sōtō Zen Buddhist practice center located in Berkeley, California led by Sojun Mel Weitsman. An informal affiliate to the San Francisco Zen Center (SFZC), BZC was founded in 1967 by Weitsman and Shunryu Suzuki as a satellite group for the SFZC. Despite founding the center, Weitsman was not installed as abbot there until 1985, one year after receiving Dharma transmission from Hoitsu Suzuki. Weitsman's Dharma heir, Alan Senauke, lives on site with his wife Laurie Senauke (as of 1999) and also works for the Buddhist Peace Fellowship. Another former teacher at BZC was Maylie Scott, who died in 2001. In 1969 Zenkei Blanche Hartman began sitting zazen at BZC, receiving Dharma transmission from Weitsman in 1988. In 1979 the center relocated to its current location on Russell Street—and today houses a small group of residents who live on site.
