An overview of R2 The Americas

5 min readLast reviewed 16 Oct 2026

The Americas is one of the four regions of the HL regional studies. Its twelve studies cover North, Central and South America and the Caribbean from about 750 to 2020: Indigenous societies before European contact, colonial rule and slavery, the independence movements, the US Civil War, the making of modern nations, the Mexican Revolution, the Great Depression, the rise of the United States as a world power, the Cold War, and the politics and social movements of the decades since.

Twelve regional studies

Each regional study is a page of its own. The chart of the twelve studies places them on one time axis.

Bar chart of the date ranges of the twelve regional studies of the Americas on one axis from 750 to 2020. R2.1 runs c. 750–1500 and R2.2 c. 1492–1830; R2.3 runs 1763–1860; the other nine studies begin between 1840 and 1960, and four of them run to 1991 or 2020.
The twelve studies of the Americas on one time axis. One covers the Indigenous societies before European contact and one the colonial era; the other ten cover the two and a half centuries from the independence movements to 2020.

Most of the studies fall after 1760, and several overlap. The Great Depression, for example, appears as a crisis in its own right and as the background to the rise of Vargas in Brazil and Cárdenas in Mexico. The table of themes groups the studies by what they are mainly about.

Studies

What they cover

Indigenous societies, conquest and colonial rule

R2.1, R2.2

Maya, Mexica (Aztec), Inca, Haudenosaunee and other societies (c. 750–1500); European conquest, Indigenous labour, the transatlantic slave trade, plantation slavery, resistance and the first abolitions (c. 1492–1830)

Independence and nation-building

R2.3, R2.4, R2.5, R2.6

The independence of the United States, Spanish America and Brazil and the Monroe Doctrine (1763–1860); slavery, the Civil War and Reconstruction (1840–1877); railways, immigration, export economies and political change (1860–1929); the Mexican Revolution from Díaz to Cárdenas (1884–1940)

Crisis and the Americas in the world

R2.7, R2.8, R2.9

The Great Depression, the New Deal and Latin American responses (c. 1920–1939); US expansion, the two world wars and the roles of Canada and Latin America (1880–1945); containment, Cuba and US intervention in the hemisphere (1945–1991)

Politics and society since the 1930s

R2.10, R2.11, R2.12

Populism, the Cuban Revolution, military rule and the return of democracy in Latin America (1934–2020); the civil rights movement and other social movements (1945–2020); presidents and prime ministers of the USA and Canada (1960–2020)

Big ideas that run through the region

The rise of the United States runs through almost every study after 1800: from the Monroe Doctrine of 1823 and the war with Mexico, through the war of 1898 and the interventions in the Caribbean, to the Good Neighbor Policy, the Cold War and the overthrow of Árbenz in Guatemala in 1954. For Canada and Latin America, managing relations with their powerful neighbour was a constant theme, and historians disagree about whether US policy was driven by security, economic interest or ideology.

Race, slavery and citizenship form a second thread. Colonial slavery, the Civil War and Reconstruction, segregation and the civil rights movement can be read as one long struggle over who belonged to the nation, and Indigenous peoples appear from the societies of 750 through conquest and dispossession to the movements for land and rights after 1945. Independence and new constitutions often changed less for Indigenous peoples, enslaved Africans and women than for the elites who led them.

A third thread is the search for stable government and economic growth. New states in Latin America faced civil war, caudillos and dependence on exports; Díaz, Vargas, Perón and the military regimes of the 1960s and 1970s each claimed to offer order and development, while democracy returned across the region in the 1980s. Historians debate how far export-led growth brought development or a lasting dependence on foreign capital and world prices. Perspectives matter throughout: for example, whether the Mexican Revolution was a genuine popular revolution, and how the reputations of Reconstruction and of presidents such as Roosevelt and Reagan have changed over time.

Tip

Where the two studies chosen follow each other in time, such as the US Civil War and the formation of modern nations, or the Great Depression and the Americas in global affairs, linking them gives each essay a stronger sense of long-term causes and consequences.

How the regional studies are studied and examined

The regional studies are taken by HL students only; SL students do not study them. Each school chooses one of the four regions (Africa and the Middle East, the Americas, Asia and Oceania, or Europe) and then two of its twelve studies, taught in about 90 hours. They are the part of IB History that builds skill in evaluating historical arguments.

The regional studies are assessed by Paper 3 (2 hours, 30 marks; 35 per cent of the HL grade). There is a separate paper for each region, with two essay questions on each of its twelve studies. Students answer two questions, each from a different study, and each essay is marked out of 15. Every question gives an argument to evaluate and asks "To what extent do you agree …?". The IB's published sample for this region is: "'The Mexican Revolution significantly changed the role of women.' To what extent do you agree with this statement?" Several studies of the Americas cover many countries or movements; questions on these can ask students to answer with reference to one country, society or movement they have studied, so at least one needs to be known in depth.

Exam tip

A strong Paper 3 essay tests the claim in the question against other factors, other groups and other periods, and reaches a clear, supported judgement; historians' views are a useful kind of perspective but not the only one. Prepare every inquiry topic of each of your two studies, because either question may come from any of them.
