During the interwar period, Latin America saw its fair share of wars and revolutions. Mexico, Colombia, and Venezuela became famous for political violence. Paris, Madrid, Washington, London, Berlin, and San Juan all got involved in those nations’ conflicts in one way or another. But the world paid comparatively little attention to what was going on in Bolivia and Peru. A revolt by indigenous peoples began in 1916, as most other nations were involved in the First Great War (a war in which Bolivia and Peru were neutral). The consequences of that rebellion would be huge. A chain of events would lead to South America becoming engulfed in war as outside powers put hundreds of thousands of boots on the ground.
In Southeastern Peru, in the 1910s, a man claiming descent from Tupac Ameru began to rally supporters to resist the mistreatment of Peru’s indigenous population. He called himself Tupac III. After a protest in Nazca was put down violently, Tupac responded by revolting against the Peruvian government. The rebels were small in number at first, mainly using guerilla warfare. But they quickly attracted followers. Much of the countryside was under rebel control. By 1920, the rebels began to attract followers from Bolivia as well. In 1921 a rebellion broke out in Northern Peru, inspired by Tupac III in the South. In December, Tupac III was shot and killed in a raid outside Arequipa. It looked as if the rebellion was going to fall apart. But a young, charismatic leader named Anca Lopez soon assumed command of the rebellion, and most of the rebels fell in line. Meanwhile, France and Spain (Madrid) sent weapons to the rebels, hoping to influence rebel leadership.
But Lopez was vigilant against any attempts to undermine his authority. French and Spanish authorities soon realized that they would not be able to control him. He killed French and Spanish agents who he viewed as imperialistic forces trying to co-opt the people’s rebellion. In retaliation, France and Spain began to give aid to the Peruvian government. Spanish monarchist agents in Lima began to give information to Lopez’s forces. Valerio Roldan was Alfonso’s man in Peru, his best agent. Roldan’s efforts were funded by Royal Spanish alcohol that was sold mainly to the Southern United States. In the summer of 1925, ten Peruvian politicians were assassinated, all in separate incidents. Roldan noticed that all the slain politicians had been vocal in their support for recognizing the Spanish government in exile in San Juan. Roldan uncovered the identity of several pro-Madrid agents, and payed local mobsters to kill them. Roldan continued to provide classified information to the rebels until he was exposed and executed in 1927.
Though Roldan never confessed, other agents did, telling Peruvian government officials what they knew about the rebels. On July 1, 500 rebel fighters were lured into a trap outside Nazca and they perished to the last man. Peruvian President José Carlos Mariátegui then issued a surprising offer of amnesty. He said that any rebel not in leadership who surrenders will be allowed to return to normal life. He also offered a bounty for “anyone who brings Anca Lopez to Lima, preferably alive.” Some rebels took the offer, but Moralez told his followers that the government wouldn’t hold up its end of the bargain. Nevertheless, government forces held the upper hand, and were gaining ground. Lopez took some of his followers across Lake Titicaca into Bolivia. They made a surprise attack on La Paz and captured it. Lopez declared himself the President of Bolivia as the actual president fled the city. Bolivian President Candelario Romero tried to rally loyal forces at Sucre, but was shot while giving a speech. Romero had been unpopular due to his extreme corruption and had made more than a few enemies. The mayor of Sucre, Bernardo Terrazas, had hired the assassin. He then assumed the position of president. He believed defeating Lopez at La Paz would be easy.
But Lopez began to rally support among the indigenous population of Bolivia, aided by his forces who had been operating in the Bolivian countryside for years. Rebel fighter in Peru were quickly running across the border. Along with La Paz, the rural areas were quickly being taken over by Lopez’s forces. Lopez also found supporters among those who had opposed Romero. He assured the upper class of the Bolivian capitol that he was no radical revolutionary. Many politicians and generals kept their jobs as they supported Lopez’s claim. Thousands of whites joined what had been a mostly indigenous movement only weeks earlier. Terrazas was also having difficulty rallying support. Soldiers were defecting at alarming rates. He began to fortify Sucre and Potosi and begged Peru for help. Peru responded by sending a small force to try and capture La Paz. Artillery shells pounded the city for a day, but the Peruvian military underestimated the resolve of the defenders and was pushed back. Civil unrest back home caused the Peruvian forces in Bolivia to withdraw in January 1928. Peruvian planes would occasionally conduct air strikes into pro-Lopez territory.

Meanwhile, pro-Lopez insurgents took over most of Southern Bolivia. Surrounded, Terrazas could only receive supplies by air from Argentina. While some suggested shooting down the Argentine planes, Lopez knew that he couldn’t win a war with Argentina. In April, Lopez’s forces captured Potosi, liberating silver miners who had been working in conditions close to slavery. Sucre held out much longer, and only fell in December. With the fall of Sucre, Bolivia was united. Lopez enacted moderate land reforms with the support of the parliament. 1929 saw border skirmishes between Peru and Bolivia. Then, in 1930, Bolivia invaded Peru. Lopez was popular in much of the country, and took several towns along the border. Peru then began conscription. The Peruvian military, bolstered by new soldiers, pushed the Bolivians out of Peru in early 1931, but went no further.
In 1933, Lopez ordered another invasion. This one was short-lived as Bolivian forced were routed at the border towns of Iñapari and Puerto Maldonado. Peruvian general Carmelo Moralez became a national hero overnight. Moralez also had political ambitions, and that was his downfall. On November 3, 1933, he was shot by a man dressed as a priest. The politicians in Lima were jealous of his popularity and a group of them conspired to assassinate the general. It was described by one source as “the single most idiotic action ever taken.” Riots broke out in most major cities. Peruvian morale plummeted and Bolivia struck back. Lopez pushed towards the coast this time, hoping he might receive supplies from Europe or the United States. The veterans in his army knew the Andes Mountains well. In December, there was a coup against the increasingly unpopular government by general Francisco Medina. The Peruvian military was starting to get back on its feet. Nevertheless, Lopez was gaining ground, aided by rebels along the way. In March 1934 Cuzco fell.
France and Spain were initially worried about a possible change in direction with the new leadership. But Medina quickly made it clear that he was pro-French and pro-Madrid. Weapons shipments increased, though many of the vehicles sent from France were close to useless in the Mountains. So, the Bolivians were lured into the much flatter town of Pisco. In August, Bolivian and Peruvian soldiers fought for the town. The Peruvians had a single Motor-gun and several armored vehicles, which won them the battle. Medina slowly pushed the Bolivians back. During the retreat, Bolivian soldiers confiscated food and supplies from local towns, and used scorched earth tactics. Before the invasion many Peruvians saw Lopez as a liberator, now he was seen as a cold-hearted tyrant. By the end of 1935, all of Peru was under Medina’s control. On New Year’s Eve, there was a ceasefire between the two nations.
While Lopez had been defeated, he lost less men than the Peruvians, and had brought back money and supplies, in addition to liberated POWs. He began to get involved in political skirmishes, notably with the mining companies and the Catholic Church. He held an election in 1936, in which his Liberty Party won 56%, while Conservative candidates won 38%, and far-left candidates won 6%. In Peru, Medina dissolved parliament. He became increasingly authoritarian and embarked on a program of eugenics. When war broke out around the world in 1936, Peru and Bolivia actually signed a joint statement of neutrality. France and Spain were obviously busy, and were unable to continue fueling the Peruvian war machine anyway. Bolivia was uninterested in war coming to South America, as Lopez feared the possibility of fighting a two-front war against Argentina and Peru.
When the war was coming to a close, some French military personnel, concerned about facing war-crimes tribunals, made their way to Peru in submarines. They received a warm welcome in Peru, where they would help the army and design superior aircraft. This was kept a secret until 1948, however. Medina used brutal repression to keep himself in power, including mass public executions in 1943. In Bolivia, Lopez’s position was becoming weaker. Members of his own party were trying to challenge him for control. In 1944, He won the Presidential election by only 3,000 votes, and many believed he used fraud to win the election. After an assassination attempt in 1945 he began arresting opposition party members. Soon there was talk behind closed doors of a coup. Lopez was aware of his increasing unpopularity, and decided to do something to rally the country; launch a fourth invasion of Peru.
While the first three invasions had widespread support, the fourth did not. Newspapers were threatened or bribed into putting a positive spin on the invasion. On September 1, 1946, the invasion began. The Peruvian front lines were broken through, but this time Peru inflicted much higher casualties on the invaders. Ecuador declared war on Bolivia. From October to December, the Bolivians attempted to take Puno, but were repeatedly pushed back. Bolivian agents trying to stir up unrest and rebellion largely failed. The Bolivian air force was also decimated. In March 1947, Medina led an offensive that pushed the Bolivians out of Peru. Then, in April, Medina gave a speech in which he declared that Lopez was a threat to all of South America, and must be removed from power. In May, Peru invaded Bolivia. With overwhelming air superiority, Peru captured Desaguadero on the 29th. La Paz was put under siege. The city’s defenders lasted until late July, at which time Lopez escaped and continued the war from the city of Trinidad in the North.
The Peruvians were advancing all along the border. In September the city of Santa Anna fell, putting Trinidad within striking distance. Bolivia was, however, able to temporarily hold back the Peruvian advance. Colombia declared war on Peru and Ecuador. Voices within the Landon cabinet spoke in favor of intervention, but Vice President Robert Taft convinced the president to not get involved. Lopez couldn’t hold out forever. In February 1948 Trinidad fell to Peruvian attackers using chemical weapons and Lopez died with a gun in his hand. Bolivian resistance continued for several months, however. Medina turned his attention to the North, where Colombia was aiming to take his ally out of the war. The Ecuadorians had been defeated at Otavalo and Quito was now under attack. In June, the beleaguered defenders were relieved by Peruvian reinforcements, who beat back the Colombians.
Bolivia was annexed by Peru and Bolivians were conscripted into the Peruvian Army. Many more were sent to do forced labor in factories producing war materiel. Peruvian doctors and scientists captured Bolivians and performed medical experiments on them. Medina declared the formation of the Peruvian Empire. Colombia was, for now, alone in its fight with Peru and Ecuador. The two nations slowly advanced into Colombian territory. In Early 1949 they took the city of Cali. Brazil then declared war, sending one force to defend Colombia, and another to invade occupied Bolivia. Peru responded by using more chemical weapons, on both soldiers and civilians. Brazilian and Colombian cities were hit by biological agents, causing hundreds of thousands of deaths. The world began to take notice of what was going on. All of South America besides Argentina placed a trade embargo against Peru, followed by Britain, Germany, Spain, Portugal, France, the US, Mexico, Mali, Japan, China, and many other nations as well.
As Peruvian air raids against Colombia continued, British and German companies came under increasing danger. In February 1950, both nations entered the conflict. In June, Patton convinced the US Congress to declare war on Peru and Ecuador. There was significant opposition to the war and both parties were split between pro and anti-war wings. Spain, Portugal, and Cuba joined in as well. Medina took the opportunity to portray himself as a man fighting for South Americans against foreign imperialists. He acted brave in public appearances. But privately, he was very afraid. The French and Spanish war criminals he was harboring were even more scared than he.
