In 1978, a prominent member of the People's Democratic Party of Afghanistan (PDPA), Mir Akbar Khyber, was killed by the government. The leaders of PDPA apparently feared that Daoud was planning to exterminate them all, especially since most of them were arrested by the government shortly after. Hafizullah Amin and a number of military wing officers of the PDPA managed to remain at large and organised an uprising.
The PDPA, led by Nur Mohammad Taraki, Babrak Karmal and Hafizullah Amin, overthrew the regime of Mohammad Daoud, who was assassinated along with his family during the April 1978 Saur Revolution. On May 1, 1978, Taraki became President, Prime Minister and General Secretary of the PDPA. The country was renamed the Democratic Republic of Afghanistan (DRA), and the PDPA regime lasted, in some form or another, until April 1992. Some believe that the 1978 Khalq uprising against the government of Daoud Khan was essentially a resurgence by the Ghilzai tribe of the Pashtun against the ruling Durranis.
Following the removal of the Soviet forces, the U.S. and its allies lost interest in Afghanistan and did little to help rebuild the war-ravaged country or influence events there. The USSR continued to support President Mohammad Najibullah (former head of the Afghan secret service, KHAD) until 1992 when the new Russian government refused to sell oil products to the Najibullah regime.
