In the 1980s, Mikhail Gorbachev's policies of perestroika and glasnost in the Soviet Union allowed political liberalisation at a regional level. This led to the creation of various informal movements all over the country, and to a rise of nationalism within most Soviet republics. In the Moldavian SSR in particular, there was a significant resurgence of pro-Romanian nationalism among Moldovans. The most prominent of these movements was the Popular Front of Moldova. In early 1988, PFM demanded that the Soviet authorities declare Moldovan the only state language, return to the use of the Latin alphabet, and recognise the shared ethnic identity of Moldovans and Romanians. The more radical factions of the Popular Front espoused extreme anti-minority, ethnocentric and chauvinist positions, calling for minority populations, particularly the Slavs (mainly Russians and Ukrainians) and Gagauz, to leave or be expelled from Moldova.
