After the 1989 revolution, the National Salvation Front (NSF), led by Ion Iliescu, took partial multi-party democratic and free market measures. In April 1990, a sit-in protest contesting the results of that year's legislative elections and accusing the NSF, including Iliescu, of being made up of former Communists and members of the Securitate grew rapidly to become what was called the Golaniad. Peaceful demonstrations degenerated into violence, prompting the intervention of coal miners summoned by Iliescu. This episode has been documented widely by both local and foreign media, and is remembered as the June 1990 Mineriad.
