The UGT worker-leader they called the Spanish Lenin, a prime minister broken between revolution and war
In November 1936 Largo Caballero appointed four CNT leaders to his cabinet: anarchists whose programme was the abolition of the state took ministerial office in one. One of them, the health minister Federica Montseny, was the first woman to hold a ministry in Spanish history.
A man who left school at seven, worked as a stucco plasterer and became a union leader. At the head of the UGT he was sentenced to life for the general strike of August 1917, and under the Primo de Rivera dictatorship he took a seat on the Council of State to keep the organization alive, a choice argued over for the rest of his life. As labour minister of the Second Republic he pushed through the eight-hour day in the countryside, and around the Asturias rising of 1934 he moved so far left that his supporters called him the Spanish Lenin. In September 1936 he became prime minister and war minister, and in November brought four CNT leaders into the cabinet, seating anarchists in a government for the first time; but he clashed continuously with the communists and the Soviet advisers over rebuilding a regular army and over the pace of the revolution.

His first chancellorship in 1920 combined the suppression of left-wing uprisings with reforms expanding disability employment, primary education, unemployment benefits and workers’ social protection. He returned as chancellor in 1928 to lead a grand coalition, which collapsed amid the Great Depression and disputes over financing unemployment insurance; he resigned in 1930.
