 Recently the Association for the Recovery of Historical Memory (ARHM) initiated a systematic search for mass graves of people executed during Franco's regime, which has been supported since the Spanish Socialist Workers' Party's (PSOE) victory during the 2004 elections by José Luis Rodríguez Zapatero's government.A "Ley de la memoria histórica de España" (Law on the Historical Memory of Spain) was approved on 28 July 2006, by the Council of Ministers, but it took until 31 October 2007, for the Congress of Deputies to approve an amended version as "The Bill to recognise and extend rights and to establish measures in favour of those who suffered persecution or violence during the Civil War and the Dictatorship" (in common parlance still known as Law of Historical Memory).The Senate approved the bill on 10 December 2007.
