Emilio Eduardo Massera (October 19, 1925 – November 8, 2010) was an Argentine military officer, and part of the 1976 coup d'état. In 1981, he was found to be a member of P2. (Wikipedia)
Propaganda Due or P2 was a Masonic lodge operating under the jurisdiction of the Grand Orient of Italy from 1877 to 1976 (when its charter was withdrawn), and a pseudo-Masonic or "black" or "covert" lodge operating illegally from 1976 to 1981. During the 1980s, when the lodge was headed by Licio Gelli, P2 was implicated in numerous Italian crimes and mysteries, including the nationwide bribe scandal Tangentopoli, the collapse of the Vatican-affiliated Banco Ambrosiano, and the murders of journalist Mino Pecorelli and banker Roberto Calvi. 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, parliamentarians, industrialists, and military leaders -- including the then-future Prime Minister Silvio Berlusconi; the Savoy pretender to the Italian throne Victor Emmanuel; and the heads of all three Italian intelligence services.
