Manuel Azaña Díaz was a Spanish politician who served as Prime Minister of the Second Spanish Republic, organizer of the Popular Front in 1935 and the last President of the Republic (1936–1939). He was the most prominent leader of the Republican cause during the Spanish Civil War of 1936–1939.
Juan Yagüe y Blanco, 1st Marquis of San Leonardo de Yagüe was a Spanish military officer during the Spanish Civil War, one of the most important in the Nationalist side. He became known as the "Butcher of Badajoz" because he ordered thousands killed, including wounded Republican soldiers in the hospital.
Juan Guilloto León, usually referred to as Modesto or Juan Modesto, was a Republican army officer during the Spanish Civil War.
The Spanish Civil War (1936–1939) broke out with a military uprising in Morocco on July 17, triggered by events in Madrid. Within days, Spain was divided in two: a "Republican" or "Loyalist" Spain consisting of the Second Spanish Republic, and a "Nationalist" Spain under the insurgent generals, and, eventually, under the leadership of General Francisco Franco.
The Battle of Badajoz was one of the first major engagements of the Spanish Civil War, resulting in a tactical and strategic Nationalist victory, however at a significant cost in time and troops. After several days of shelling and bombardment, Nationalists stormed the fortified border city of Badajoz on August 14, 1936, cutting off the Spanish Republic from neighbouring Portugal and linking the northern and southern zones of Nationalist control.
The Battle of Mérida saw the Republican militia twice fail to halt the Spanish Army of Africa near the historic town of Mérida early in the Spanish Civil War.
The Battle of Brunete, fought 24 kilometres (15 mi) west of Madrid, was a Republican attempt to alleviate the pressure exerted by the Nationalists on the capital and on the north during the Spanish Civil War. Although initially successful, the Republicans were forced to retreat from Brunete after Nationalist counterattacks, and suffered devastating casualties from the battle.
The siege of Madrid was a two-and-a-half-year siege of the Republican-controlled Spanish capital city of Madrid by the Nationalist armies, under General Francisco Franco, during the Spanish Civil War (1936–1939). The city, besieged from October 1936, fell to the Nationalist armies on 28 March 1939. The Battle of Madrid in November 1936 saw the most intense fighting in and around the city when the Nationalists made their most determined attempt to take the Republican capital.
The Battle of the Sierra Guadalupe, also known as the Tagus Campaign, was a continuation of the Nationalist Army's race north toward Madrid in the early stages of the Spanish Civil War. In mid-late August 1936, the three Regulares columns of General Yagüe's Army of Africa dashed through the Sierra de Guadalupe Mountains, also known as Sierra de Villuercas, in central Spain and forded across the Tagus River, capturing several towns and routing the Republicans in a succession of rapid advances.
The War in the North was the campaign of the Spanish Civil War in which the Nationalist forces defeated and occupied the parts of northern Spain that had remained loyal to the Republican government.
The campaign of Gipuzkoa was part of the Spanish Civil War, where the Nationalist Army conquered the northern province of Gipuzkoa, held by the Republic.
The Battle of Irún was the critical battle of the Campaign of Gipuzkoa prior to the War in the North, during the Spanish Civil War. The Nationalist Army, under Alfonso Beorlegui, captured the city of Irún cutting off the northern provinces of Gipuzkoa, Biscay, Santander, and Asturias from their source of arms and support in France.
The Spanish Civil War was a military conflict fought from 1936 to 1939 between the Republicans and the Nationalists. Republicans were loyal to the left-leaning Popular Front government of the Second Spanish Republic, and consisted of various socialist, communist, separatist, anarchist, and republican parties, some of which had opposed the government in the pre-war period. The opposing Nationalists were an alliance of Falangists, monarchists, conservatives, and traditionalists led by a military junta among whom General Francisco Franco quickly achieved a preponderant role. Due to the international political climate at the time, the war had many facets and was variously viewed as class struggle, a religious struggle, a struggle between dictatorship and republican democracy, between revolution and counterrevolution, and between fascism and communism. According to Claude Bowers, U.S. ambassador to Spain during the war, it was the "dress rehearsal" for World War II. The Nationalists won the war, which ended in early 1939, and ruled Spain until Franco's death in November 1975.
The Badajoz massacre occurred in the days after the Battle of Badajoz during the Spanish Civil War. Between 500 and 4,000 civilian and military supporters of the Second Spanish Republic were murdered by the Nationalist forces after the seizure of the town of Badajoz on August 14, 1936.
The Paracuellos massacres were a series of mass killings of civilians and prisoners of war by the Republican faction of the Spanish Civil War that took place before and during the Siege of Madrid during the early stages of the war. The death toll remains a subject of debate and controversy.
The Battle of Guadarrama was the first battle in the Spanish Civil War involving troops loyal to the Second Spanish Republic in the Sierra de Guadarrama. The battle took place in the last week of July and in early August 1936. The Nationalist side sent by General Mola was attempting to cross the mountain passes of the Sierra de Guadarrama and reach Madrid by the North, but the Republican side, made up of militiamen and troops disbanded by the government left Madrid to stop the Nationalists. The Republican side was successful and the Nationalist troops did not manage to cross the mountain passes.
The Extremadura campaign was a campaign in Extremadura, Spain during the Spanish Civil War. It culminated in the Battle of Badajoz in August 1936, from which the troops of the Army of Africa under the command of Francisco Franco moved quickly to begin the march to Madrid.
The Battle of Seseña was a Republican-Soviet assault on the Nationalist stronghold of Seseña, near Toledo, 30 km south of Madrid in October 1936 during the Spanish Civil War. After the fall of Talavera de la Reina and Toledo in September 1936, the Nationalist troops pushed towards Madrid and in October they were 30 km from the city. The Republican government which had received new Soviet weapons decided to launch a counteroffensive in order to stop the Nationalist offensive at Seseña. The attack failed and the Nationalists resumed their advance towards Madrid. The battle is notable for being the first time that massive tank warfare was seen in the Spanish War and for the use by Nationalist troops of Molotov cocktails against Soviet T-26 tanks.
The siege of Gandesa took place between July and November 1938 during the Spanish Civil War, a few months after a battle in the same town.
The Spanish Republican Army was the main branch of the Armed Forces of the Second Spanish Republic between 1931 and 1939.
