A curated collection of ILN reports and images covering the Spanish Civil War — political background, major battles and key personalities.
The Spanish Civil War (1936–1939) began with a military uprising against the Republican government in July 1936. The conflict rapidly polarised Spanish society and drew international attention — the Nationalists (led by Francisco Franco) were supported by Fascist Italy and Nazi Germany, while the Republicans received aid from the Soviet Union and volunteers from the International Brigades. The war reshaped Spain and had wide-reaching cultural and political consequences across Europe.
On this page you will find ILN scans, captions, short biographies, and selected contextual notes to help readers understand the events and principal actors.

Who Were the Rebels?
The Rebels — later known as the Nationalists — were led by General Francisco Franco and other senior officers who rose in July 1936 against Spain’s elected Popular Front government, the left-wing administration of the Second Spanish Republic. Their ranks included much of the regular army, particularly units from Spanish Morocco, together with monarchists, conservatives, and members of the Falange (Spain’s fascist movement). They received crucial support from Nazi Germany, Fascist Italy, and Portugal.
The opposing Republicans comprised socialists, communists, anarchists, and regional nationalists, supported by the Soviet Union and the International Brigades of foreign volunteers.

Short historical note
The war was fought on multiple fronts and combined conventional battles with sieges (Guernica, Madrid, Bilbao) and aerial bombardment (notably Guernica in 1937). It ended in early 1939 with a Nationalist victory and Franco's long rule. The conflict was a testing ground for new military tactics and an ideological prelude to World War II.
