André Léon Blum (French pronunciation: [leɔ̃ blym]; 9 April 1872 – 30 March 1950) was a French politician, usually identified with the moderate left, and three times Prime Minister of France.

While in his youth an avid reader of the works of the nationalist writer Maurice Barrès, Blum had little interest in politics until the Dreyfus Affair of 1894, which had a traumatic effect on him as it did on many French Jews. Campaigning as a Dreyfusard brought him into contact with the socialist leader Jean Jaurès, whom he greatly admired. He began contributing to the socialist daily, L'Humanité, and joined the Socialist Party, then called the SFIO. Soon he was the party's main theoretician.

In July 1914, just as the First World War broke out, Jaurès was assassinated, and Blum became more active in the Socialist party leadership. In August 1914 Blum became assistant to the Socialist Minister of Public Works Marcel Sembat. In 1919 he was chosen as chair of the party's executive committee, and was also elected to the National Assembly as a representative of Paris. Believing that there was no such thing as a "good dictatorship", he opposed participation in the Comintern. Therefore, in 1920, he worked to prevent a split between supporters and opponents of the Russian Revolution, but the radicals seceded, taking L'Humanité with them, and formed the SFIC.

Roger Henri Charles Salengro (born May 30, 1890 in Lille, died November 18, 1936 in Lille) was a French politician. He achieved fame as Minister of the Interior during the Popular Front government in 1936. He committed suicide a few months after taking office, after being hounded by a calumny campaign orchestrated by extreme right-wing newspapers.

In 1909, Salengro enrolled at the University of Lille to study literature. The same year, he joined the French Section of the Workers' International, a socialist party, and founded a left-wing students' organisation.

In 1914, he signed up to join the French military for the First World War, despite having spoken out as a pacifist in previous years. Captured by the Germans on October 7, 1915, he became a prisoner of war. He refused to work in a German factory, and was incarcerated. His treatment was harsh; he weighed only 42 kg when he was freed after the war.

In 1918, he became a journalist, and resumed his involvement in politics. In 1919, he was elected municipal councillor in Lille, and general councillor of the Lille-Sud-Ouest canton.

The Spanish Civil War was a major conflict fought in Spain from 17 July 1936 to 1 April 1939. The war began after a pronunciamiento (declaration of opposition) by a group of generals under the leadership of José Sanjurjo against the elected government of the Second Spanish Republic, at the time under the leadership of President Manuel Azaña. The rebel coup was supported by a number of conservative groups including the Spanish Confederation of the Autonomous Right, monarchists such as the religious conservative Carlists, and the Fascist Falange. The uprising was authoritarian and anti-separatist in inspiration; anti-Basque and anti-Catalan feeling marked the Nationalist zone.

Following the only partially successful coup, Spain was left militarily and politically divided. From that moment onwards, general Francisco Franco began a protracted war of attrition against the established government for the control of the country. The rebel forces received the support of Nazi Germany and the Kingdom of Italy, as well as neighbouring Portugal, while the Soviet Union and Mexico intervened in support of the Republican government or loyalist side.
