The Democratic Republic of Afghanistan, later known as the Republic of Afghanistan, was the left-wing led Afghan state from 1978 to 1992. It was bordered by Pakistan to the east and south, by Iran to the west, by the Soviet Union to the north, and by China to the northeast. Established by the People's Democratic Party of Afghanistan (PDPA) following the Saur Revolution in April 1978, it came to rely heavily on the Soviet Union for financial and military assistance and was therefore widely considered to be a Soviet satellite state. The PDPA's rise to power is seen as the beginning of the ongoing Afghan conflict, and the majority of the country's years in existence were marked by the Soviet–Afghan War. It collapsed by the end of the First Afghan Civil War in April 1992, having lasted only four months after the dissolution of the Soviet Union.
