During the 1980s the democratic restoration made possible a growing open society. New cultural movements based on freedom appeared, like La Movida Madrileña and a culture of human rights arose with Gregorio Peces-Barba. On 30 May 1982 Spain joined NATO, followed by a referendum after a strong social opposition. That year the Spanish Socialist Workers Party (PSOE) came to power, the first left-wing government in 43 years. In 1986 Spain joined the European Economic Community, which later became the European Union. The PSOE was replaced in government by the Partido Popular (PP) in 1996 after scandals around participation of the government of Felipe González in the Dirty war against ETA; at that point the PSOE had served almost 14 consecutive years in office.
