The party's first leader was Achille Occhetto, the final party secretary of the PCI. Although Ochetto had proclaimed the end of Communism, the new party's logo consisted of an oak tree sprouting from the previous symbol of the PCI in a roundel at the tree's roots. This logo was adopted not only to allow the PDS to trade on the PCI's roots but to keep any potential splinter party from immediately adopting the old PCI symbol. This did not prevent hard-liners leaving the party and launching the Communist Refoundation Party (PRC).[7] In 1993, the PDS was admitted into both the Socialist International and the Party of European Socialists (PES).[8] In the same year, the party's Members of the European Parliament moved from the European United Left to the PES group in the European Parliament.[9] In 1996, the PDS explored the possibility of adopting the fist and rose emblem of the Socialist International but was prevented to do it by the Transnational Radical Party, which had obtained the right to use it in Italy in the 1970s.[10]
In the 1992 Italian general election, the PDS reached second place with 107 seats in the Chamber of Deputies and 64 in the Senate. The PDS had briefly entered the national unity government of the Ciampi Cabinet, headed by Carlo Azeglio Ciampi, on 29 April 1993, holding three ministries. Both the PDS and Federation of the Greens quickly withdrew from the cabinet on 4 May 1993 in protest against the Chamber's refusal to begin prosecution of former Prime Minister Bettino Craxi.[11] The party's transformation from the PCI to the PDS happened with the background of Tangentopoli and the end of the First Republic, when the dominant Christian Democracy and four other establishment parties collapsed and were replaced by new political formations during 1992–1994.[12]
