Illustrated timeline of the Spanish Civil War (short)

Most of the images included in this timeline are from documents made available online as part of our Spanish Civil War digitisation project.

A note about terms: supporters of the Spanish government during the Spanish Civil War are usually referred to as Republicans (Republican leaders included Francisco Largo Caballero and Juan Negrín); supporters of the military coup against the government are usually referred to as Nationalists (Nationalist leaders included General Francisco Franco and General Emilio Mola).

Election map of Spain, 1936 16 February 1936

Elections held for the Cortes (Spanish parliament). They are won by the 'Popular Front' (a coalition of left-wing political parties).

General Franco and General Mola

Meeting of army officers in Madrid (including General Mola and General Franco) to discuss a military coup against the Popular Front government.

Members of the Falange

15 March 1936

The government bans the Falange, a Spanish fascist organisation. Its leader, José Antonio Primo de Rivera, is arrested for illegal possession of weapons.

The Falange was banned after members tried to assassinate Luis Jiménez Asúa, a Socialist member of the Cortes, on 10 March, and the trade union leader Francisco Largo Caballero on 14 March.

Map of Spain shortly after the coup

17-18 July 1936

Start of military rebellion against the Spanish government in North Africa, then mainland Spain.

Distribution of weapons to supporters of the government

19-20 July 1936

The military uprising is defeated in Madrid and Barcelona. Morocco, Galicia, Navarre, Old Castile and Seville soon come under the control of the rebels. The intended leader of the coup, General Sanjurjo, is killed when the aeroplane carrying him from Portugal to Spain crashes.

The relief of Alcazar

21 July - 27 September 1936

Members of the Civil Guard and military cadets are besieged in the Alcazar citadel, in Toledo, by pro-government forces. After more than two months the siege was raised by Nationalist troops commanded by General Franco.

The relief of Alcazar was seen as a great symbolic victory by the Nationalists, and stories of 'red' atrocities towards civilians during the siege were used in anti-government propaganda.

German bombs sent to Spain

Late July 1936 onwards

Italian and German military supplies, including aircraft, are received by the rebels in North Africa and Spain. The Soviet Union agrees to send aid to the Republican side.

Italian torpedo August 1936

A "non-intervention" agreement, banning military intervention in Spain by other countries, is proposed and promoted by the French and British governments. Key governments (including those of Portugal, Germany, Italy and the Soviet Union) agree to this in principle. In practise Germany, Italy and the Soviet Union continue to send military supplies throughout the war.


14 August 1936

Capture of the city of Badajoz (near the Portuguese border) by Nationalist forces commanded by Lieutenant Colonel Juan Yagüe. The massacre of an estimated 2,000 - 4,000 civilians followed.

Badajoz was used in Republican propaganda as a symbol of Nationalist barbarism. The Nationalists' use of Moroccan troops ("Moors") to carry out atrocities against Spaniards in Badajoz and elsewhere was often highlighted.

Francisco Largo Caballero

4 September 1936

Francisco Largo Caballero becomes Republican Prime Minister. His coalition government would include socialists, communists, Left Republicans, Basque nationalists and (after 4 November 1936) anarchists.


5 September 1936

The Basque town of Irun is taken by the Nationalists.

Large areas of the town were set on fire as Republican troops retreated (an act usually attributed to supporters of the anarchist CNT-FAI). Nationalists would later use the example of Irun as supporting evidence when they argued that the destruction of towns such as Guernica was caused by Republican arson rather than Nationalist bombing.

Rebel leaders agree that General Franco should be appointed supreme commander of the Nationalist forces (Generalissimo).

Farewell parade of the International Brigade

4 October 1938

Withdrawal of the International Brigade from the front.
