Banco Ambrosiano was an Italian bank that collapsed in 1982. At the centre of the bank's failure was its chairman, Roberto Calvi and his membership in the illegal Masonic Lodge Propaganda Due (aka P2). Vatican Bank was Banco Ambrosiano's main shareholder, and the death of Pope John Paul I in 1978 is rumored to be linked to the Ambrosiano scandal. Vatican Bank was also accused of funneling covert United States funds to Solidarity and the Contras through Banco Ambrosiano.
