Propaganda Due

Propaganda Due, or P2, was a Masonic lodge operating under the jurisdiction of the Grand Orient of Italy from 1945 to 1976 (when its charter was withdrawn), and a pseudo-Masonic, "black", or "covert" lodge operating illegally (in contravention of Article 18 of the Constitution of Italy banning secret associations) from 1976 to 1981. During the years that the lodge was headed by Licio Gelli, P2 was implicated in numerous Italian crimes and mysteries, including the collapse of the Vatican-affiliated Banco Ambrosiano, the murders of journalist Mino Pecorelli and banker Roberto Calvi, and corruption cases within the nationwide bribe scandal Tangentopoli. P2 came to light through the investigations into the collapse of Michele Sindona's financial empire.

P2 was sometimes referred to as a "state within a state" or a "shadow government". The lodge had among its members prominent journalists, members of parliament, industrialists, and military leaders—including Silvio Berlusconi, who later became Prime Minister of Italy; the Savoy pretender to the Italian throne Victor Emmanuel; and the heads of all three Italian intelligence services (at the time SISDE, SISMI and CESIS).

When searching Licio Gelli's villa, the police found a document called the "Plan for Democratic Rebirth", which called for a consolidation of the media, suppression of trade unions, and the rewriting of the Italian Constitution.

Outside Italy, P2 was also active in Uruguay, Brazil and in Argentina, with Raúl Alberto Lastiri, Argentina's interim president (between July 13, 1973 to October 12, 1973) during the height of the "Dirty War" among its members. Emilio Massera, who was part of the military junta led by Jorge Rafael Videla from 1976 to 1978, José López Rega, minister of Social Welfare in Perón's government and founder of the Argentine Anticommunist Alliance ("Triple A"), and General Guillermo Suárez Mason were also members.
