The 1979 Soviet invasion in support of a communist government triggered a major intervention of religion into Afghan political conflict, and Islam united the multi-ethnic political opposition. Once the Soviet-backed Marxist-style regime came to power in Afghanistan, the People's Democratic Party of Afghanistan (PDPA) moved to reduce the influence of Islam. The "atheistic" and "infidel" communist PDPA imprisoned, tortured and murdered many members of the religious establishment. After National Reconciliation talks in 1987, Islam became once again the state religion and the country removed the word "Democratic" from its official name. From 1987-1992, the country's official name was the Republic of Afghanistan but today it is an Islamic Republic. For Afghans, Islam represents a potentially unifying symbolic system which offsets the divisiveness that frequently rises from the existence of a deep pride in tribal loyalties and an abounding sense of personal and family honor found in multitribal and multiethnic societies such as Afghanistan. Mosques serve not only as places of worship, but for a multitude of functions, including shelter for guests, places to meet and converse, the focus of social religious festivities and schools. Almost every Afghan has at one time during his youth studied at a mosque school; for some this is the only formal education they receive.
