In late August 1989, the Popular Front of Moldova organized a mass demonstration in Chişinău, that became known as the Great National Assembly, which pressured the authorities of the Moldovan Soviet Socialist Republic to adopt a language law on August 31, 1989 that proclaimed the Moldovan language written in the Latin script to be the state language of the MSSR.
Its identity with the Romanian language was also established. On June 23, 1990 the Moldovan Parliament established August 31 as a national language day.
