France at the end of the 1920s had apparently recovered its prewar stability, prosperity, and self-confidence. For a time it even seemed immune to the economic crisis that spread through Europe beginning in 1929; France went serenely on behind its high-tariff barrier, a healthy island in a chaotic world. By 1931, however, France in its turn succumbed to the effects of the Great Depression, and the impact was no less severe than elsewhere.

In 1932 the right-wing parties lost control of the Chamber to the Radicals and Socialists. The Radical leader Édouard Herriot returned to the premiership, with Socialist support but not participation. During the next two years Herriot and a series of successors groped for a solution to the deepening crisis. French nervousness was increased by the surge of Nazi power across the Rhine, culminating in Adolf Hitler’s accession to the chancellorship in January 1933. Right-wing movements in France—some openly fascist, others advocating a more traditional authoritarianism—grew in size and activity. By 1934 the shaky coalition was at the mercy of an incident—the Stavisky scandal, a sordid affair that tarnished the reputations of several leading Radicals. Antiparliamentary groups of the far right seized the occasion to demonstrate against the regime; on February 6 a huge rally near the Chamber of Deputies degenerated into a bloody battle with armed police, during which 15 rioters were killed and 1,500 injured. Premier Édouard Daladier, confronted by a threat of civil war, resigned in favour of a national union cabinet under former president Gaston Doumergue. The regime survived the crisis, but serious stress persisted. Right-wing agitation was countered by unity of action on the left, grouping all the left-wing parties and the CGT; even the Communists participated in this effort, which culminated in 1935 in the formation of the Popular Front.

Doumergue’s government had meanwhile disintegrated when Radical ministers resigned over the premier’s increasingly authoritarian tone. Doumergue was soon replaced by Pierre Laval, a former socialist who had migrated toward the right. Laval embarked on a vigorous but unpopular attempt to combat the Depression through traditional techniques: sharp cuts in government spending and increased taxes. These policies wrecked his cabinet early in 1936 and became campaign issues in the parliamentary election that spring. That election, probably the most bitterly contested since 1877, gave the Popular Front a narrow majority of the popular vote and a large majority in the Chamber. The Socialists for the first time became the largest party; but the greatest proportional gain went to the Communists, who jumped from 10 to 72 seats.

Blum, the Socialist leader, became premier. An intellectual, Blum was the first French premier of Jewish origin. His ministers were mostly Socialists and Radicals; the Communists refused his urgent invitation to participate. At the very outset, a wave of sit-down strikes spread throughout the country, expressing workers’ pent-up resentment toward past governments and their determination to get what they considered to be justice. Blum persuaded industrial leaders to grant immediate wage increases, which ended the strike. Then he pushed additional reforms through parliament: the 40-hour workweek, paid vacations, collective bargaining, and the seminationalization of the Bank of France. Many other reform bills, however, were stalled in committee or in the Senate, which remained much more conservative than the Chamber.

Blum’s social reforms were costly and controversial and were not buttressed by a program of economic reforms that might have stimulated production and restored confidence. Production surged briefly, then lagged again; unemployment remained high, rising prices offset wage gains, a flight of capital set in. When Blum attempted to impose exchange controls, the Senate rebelled and overthrew his cabinet (June 1937). The Popular Front held together for another year, but the Socialists and Radicals were irretrievably divided on economic policy. In April 1938 France returned once more to the usual pattern of unstable centre coalitions, with the Socialists in opposition. The Radical Daladier served as premier in 1938–40; his finance minister, Paul Reynaud, suspended most of the Popular Front reforms and sought economic recovery through more orthodox policies favoured by business.
