During the 1980s, the Marxist underpinnings of the PZPR steadily eroded, and, long before the round table talks, the ruling party had lost its ideological fervor. Official PZPR documents compiled in May 1987 revealed that only about 25 percent of the membership were politically active, more than 60 percent paid their dues but were inactive, and 15 percent did not even pay their dues. By that time, protecting the national interest had replaced Marxist doctrine as the guiding principle of the government's actions. For example, the Jaruzelski regime characterized its imposition of martial law in 1981 not as an attempt to restore Marxist purity but as a preemptive measure to avoid Soviet military intervention in Poland. The PZPR had accepted the necessity of economic decentralization, privatization, and price liberalization, realizing that to regain political legitimacy it had to win the cooperation of the opposition.

Despite its enormous advantage in institutional and monetary resources, control of the electronic media and most print media, and a slate of reformist, nonideological candidates, the PZPR suffered an overwhelming defeat in the parliamentary elections of June 1989. Once the parties that were its traditional allies had repositioned themselves with Solidarity to install a noncommunist government, the PZPR had become a political relic. In January 1990, at its final congress (the eleventh), the PZPR patterned itself after Western social democratic parties and adopted the name Social Democracy of the Republic of Poland (Socjaldemokracja Rzeczypospolitej Polski--SdRP).

The SdRP, which inherited the assets and infrastructure of the PZPR, was a political force that could not be ignored in the reform era. During the 1990 presidential elections, for example, the SdRP candidate received 9 percent of the vote. At its first national convention in May 1991, the party adopted a platform supporting pluralistic democracy, a parliamentary form of government, strict separation of church and state, women's rights, environmental protection, the right to work, a generous social safety net, and good relations with all of Poland's neighbors. In July 1991, preparing for the October parliamentary elections, the SdRP invited other groups with a communist lineage to join it in a broad coalition, the Alliance of the Democratic Left (Sojusz Lewicy Demokratycznej--SLD). The most important of these groups was the All-Polish Alliance of Trade Unions (Ogólnopolskie Porozumienie Zwiazków Zawodowych--OPZZ), which Jaruzelski had created in 1984 to co-opt Solidarity's influence among the working people. By the time of the 1991 elections, the OPZZ had a larger membership than Solidarity. Of the 390 SLD candidates for the parliamentary elections of October 1991, 45 percent were members of the SdRP and about one-third belonged to the OPZZ. The SLD surprised most political observers by finishing a close second to the Democratic Union and winning sixty Sejm and four Senate seats. Its failure to expand its membership, however, made the SLD a political outcast in the coalition-building efforts that followed the 1991 election.
