The big idea: Juan Perón is the key Americas example of an authoritarian state for Paper 2. He rose from an army officer to an elected president by building a mass following among workers, then bent Argentina's institutions to keep himself in charge.

Picture Argentina in the early 1940s. It was a wealthy but unstable country, ruled by a narrow group of landowners and generals, and shaken by military coups. In June 1943 a group of army officers overthrew the elected government, worried that Argentina might be dragged into the Second World War on the Allied side and angry at corruption and the old order.

Colonel Juan Perón was one of these officers. He did not lead the 1943 coup, but he was quick to grab the department that mattered most: the Secretariat of Labour and Welfare, created that October.

From that unglamorous post, Perón built an entire political movement. He raised wages, backed union rights, and set up pensions and paid holidays for ordinary workers, who came to be called the descamisados.

By 1945 Perón held several government posts at once (Labour Secretary, War Minister and Vice-President) and rival officers grew alarmed at his growing power. They arrested him on 9 October 1945.

The turning point: 17 October 1945: Union leaders called workers onto the streets of Buenos Aires. Huge crowds of descamisados demanded his release, and the frightened government freed him within a day.

This single event, still marked every year as Loyalty Day, proved Perón had a genuine mass base and launched his run for the presidency.

Perón resigned from the army, married the radio actress Eva Duarte (Evita) in December 1945, and ran for president backed by a new coalition of unions and nationalists called the Labour Party. He won the election of 24 February 1946 with about 52% of the vote, a genuinely popular result, and was inaugurated on 4 June 1946.

How Perón rose to power

1

1943: the military coup

Army officers, unhappy with corrupt civilian rule and fearing entry into the Second World War, overthrew the government on 4 June 1943. Perón was a minor figure in the coup itself.

2

1943-45: building a base

As head of the new Secretariat of Labour and Welfare, Perón championed union rights, wage rises and welfare for workers, winning huge personal loyalty among the descamisados.

3

October 1945: arrest and release

Rival officers arrested Perón on 9 October 1945. Mass worker demonstrations on 17 October forced the government to free him within a day, showing his real popular power.

4

1946: election victory

Perón resigned his commission, married Eva Duarte, and won the presidential election of 24 February 1946 with about 52% of the vote on a Labour Party-led coalition ticket.

An officer built a worker following, survived an arrest, then won a real election.

DateEventWhy it matters
4 Jun 1943Military coup topples civilian governmentPerón enters government as an army officer, not yet as leader
Oct 1943Perón heads the Secretariat of Labour and WelfareHe builds a mass base among workers, the descamisados
9 Oct 1945Rival officers arrest PerónShows the old elite feared his growing power
17 Oct 1945Mass worker protests free PerónProves genuine popular support, becomes 'Loyalty Day'
24 Feb 1946Wins presidential electionLegal, electoral route to power, about 52% of the vote
Legal route, not a coup: Unlike some authoritarian leaders, Perón reached the presidency through a real election in 1946, not by seizing power himself. His authoritarian methods came after this, in how he then consolidated and used that power.

Winning the 1946 election was only the start. Perón then spent his first term reshaping Argentina's laws, unions, courts and media so that his power would be very hard to challenge.

How Perón consolidated and kept power

1

A new constitution

The 1949 constitution allowed a president to be re-elected immediately (Perón had been barred from a second consecutive term before), and expanded workers' and social rights. It concentrated power in the presidency.

2

Controlling the unions

Perón fused the main union federation, the CGT, into his movement. Loyal unions gave him a permanent organised base, but independent unions and strikes outside his control were crushed.

3

Force and repression

Opposition politicians, judges and journalists faced arrest, dismissal or exile. Independent newspapers, including the major paper La Prensa, were closed down or seized by 1951, and the political police watched dissenters.

4

Charisma and cult of personality

Perón and his wife Eva were presented as the parents of the nation. Portraits, slogans and rallies built a cult of personality around 'Perón' and 'Evita' that went well beyond ordinary popularity.

5

Propaganda machine

Radio, state-backed newspapers and school textbooks spread Justicialist doctrine and loyalty to Perón to children and adults alike, while censorship silenced critical voices.

New laws, loyal unions, control of the courts and press, then a cult of personality around the Peróns.

Eva Perón's role: Eva Perón (Evita) was not just a supportive wife. She ran the Eva Perón Foundation, a huge charity that handed out aid, homes, medicine and toys directly to the poor, building loyalty that bypassed ordinary government and Congress.

She also led the campaign for women's votes and headed the Peronist Women's Party. Her early death from cancer in 1952, at only 33, turned her into a near-saint-like symbol for Peronism.
Cult of personality versus real charisma: Perón had genuine, earned charisma from his years running the Labour Secretariat. But the regime added a manufactured cult on top: statues, renamed cities (La Plata briefly became 'Eva Perón City'), portraits in schools, and compulsory chants of loyalty. Exam answers should separate the real popularity from the state-manufactured cult.

Foreign policy also shaped how long Perón could hold on. His Third Position claimed neutrality between the capitalist United States and the communist Soviet Union, which boosted Argentine nationalist pride at first.

But by the mid-1950s this foreign policy brought no allies and no aid when Argentina's economy soured, leaving Perón isolated. A serious clash with the Roman Catholic Church from 1954, after Perón legalised divorce and moved to separate church and state, cost him a crucial ally and helped the military turn against him.

Perón's programme was called Justicialism, a mix of nationalism, state control of the economy and welfare for workers. It reshaped Argentina fast, but the results were mixed, and the whole system began to crack by the mid-1950s.

Perón's policies and their real results

1

The economy

Perón nationalised the railways, telephones and the central bank, and pushed import substitution industrialisation to reduce reliance on Britain and the US. Early growth and full employment pleased workers, but by the early 1950s exports fell, inflation rose and the state ran short of money.

2

Workers and welfare

Wages, pensions, paid holidays and labour protections expanded hugely for unionised workers, which is why the descamisados stayed loyal even as economic problems grew.

3

Women and the vote

Argentina passed women's suffrage in September 1947, letting women vote in national elections for the first time, in the 1951 election. Eva Perón led this campaign and organised the new Peronist Women's Party, though within a movement tightly controlled from the top.

4

The Church and minorities

Perón first courted the Catholic Church, then clashed with it badly from 1954 over divorce law and secular education, losing a major ally. Political opponents, rather than ethnic minorities, were the main target of repression under Perón.

Big welfare and nationalist wins at first, then economic strain and repression.

The 1955 overthrow: Economic strain, the break with the Church, and a military worried about Perón's grip on power combined. The armed forces overthrew him in September 1955 in a coup known as the Revolución Libertadora ('Liberating Revolution'), and Perón fled into exile. He briefly returned to the presidency in 1973 but died in office in July 1974.
Using Perón in Paper 2: Perón's region is the Americas, so pair him with a leader from a different region, such as Hitler or Stalin in Europe, or Mao in Asia. Never pair him with Castro or another Americas leader.

He is strong evidence for legal/electoral routes to power, for the role of a charismatic partner (Eva Perón) in sustaining a regime, and for how economic strain and loss of key allies (the Church, the military) can bring an authoritarian leader down.
