The Socialist Party (PS) achieved the biggest electoral success of their history. This result marked the triumph of Mitterrand's strategy. Like the GaullistUnion of Democrats for the Republic in 1968, the PS obtained an absolute parliamentary majority. The French Communist Party (PCF) obtained its poorest result since 1936 and lost the half of its MPs, most of them to the PS. However, four Communists became members of Pierre Mauroy's government. This was the first PCF governmental participation since 1947. The two main right-wing parliamentary parties, the Rally for the Republic (RPR) and Union for French Democracy (UDF), lost the half of their seats too. This result earned the nickname "the pink wave" from the press.
Background
On 10 May 1981 François Mitterrand was elected president, becoming the first Socialist to win a presidential election under universal suffrage. It was also the first occasion of alternance (between the right and the left) in government during the Fifth Republic.
The new head of state nominated Pierre Mauroy to lead a Socialist cabinet. He then dissolved the National Assembly so that he could rely on a parliamentary majority. The left had lost the 1978 legislative election and the full term of the National Assembly would have expired in 1983.
Campaign
Knocked out after its defeat in the recent presidential election, the right campaigned against the concentration of the powers and the possible nomination of Communist ministers. However, it suffered from the economic crisis, the will for change amongst the electorate, and the rivalry between RPR leader Jacques Chirac and previous UDF President Valéry Giscard d'Estaing. The formation of the Union for a New Majority appeared as a false reconciliation and so, had not convinced voters. Furthermore, as the PCF had been declining, and was no longer the dominant party of the Left, it did not seem to be a real danger.
The Communist leaders were very disappointed by the result of their candidate, Georges Marchais, in the presidential election, and very worried by the legislative elections. During the presidential campaign, the PCF had denounced the "turn towards the right" of the Socialist Party, in vain. It understood that Mitterrand was ready to win his bet, expressed in the 1972 Congress of the Socialist International, to capture 3 of the 5 million PCF voters. Perceiving the great hope of the left-wing voters after Mitterrand's election, Marchais signed a "contract of government" with the First Secretary of the PS Lionel Jospin.
