Renziani, previously known as Now! (Adesso!) and Big Bang, is a liberal and modernizing movement within the Democratic Party (PD), a political party in Italy. Its leader is Matteo Renzi, party's national secretary and Prime Minister of Italy.
The Open Foundation (Fondazione Open), whose Secretary-General is Maria Elena Boschi, serves as think tank and financial arm of the faction.
The movement, which has never been organised as a formal faction, grew around Matteo Renzi, mayor of Florence since 2009. Born in 1975, Renzi is a devout Catholic (he has been a scout leader of AGESCI) and a moderate. He started his political career in the Italian People's Party and was elected president of the Province of Firenze in 2004, when he was just 29. Through Democracy is Freedom – The Daisy he joined the PD in 2007. A frequent critic of his party's leadership, especially under Pier Luigi Bersani, Renzi made his name as "scrapper" (of old leaders and ideas), advocate of complete change in the party, reformer and modernizer.
After organizing a convention of "scrappers" in Florence in November 2010, Renzi repeated the event in November 2011 under the Big Bang name. Leading Democrats who took part to the convention included Sergio Chiamparino, Arturo Parisi, Graziano Delrio, Ermete Realacci, Andrea Marcucci and Roberto Giachetti, but most of the speakers were people from the civil society, mainly entrepreneurs, artists and intellectuals. Among the ideas espoused by Renzi and his fellow Big-Bangers, many were genuinely liberal for a social-democratic party: labour market flexibility, abolition of professional bars, pension reform and cuts in public sector. This was seens as the platform for a Renzi's run for prime-ministerial candidate of the PD. Renzi's group was dubbed by some journalists as the party's "new right".
