  • Leaders who steered the Americas into the modern era
  • A case study: Porfirio Díaz in Mexico
  • African American life, 1865–1929: from Jim Crow to the Harlem Renaissance

By the late 1800s, the countries of the Americas were being reshaped by railroads, cities and new ideas (covered in the first half of this topic). But individual leaders also mattered. The syllabus names three: Theodore Roosevelt (United States), Wilfrid Laurier (Canada), and any one Latin American leader. Each tried to modernize their country politically and economically — with real successes, and real failures.

Theodore Roosevelt (US president, 1901–1909)

  • Political aims — break the power of trusts (giant monopolies); expand the federal government's role as a referee between big business and ordinary citizens; his approach was called the Square Deal
  • Trust-busting — used the Sherman Antitrust Act to sue over 40 companies, most famously breaking up the Northern Securities railroad monopoly in 1904
  • Conservation — created 5 national parks and over 100 million acres of national forest, tying modernization to protecting natural resources
  • Economic aims — supported the gold standard, tariffs that protected US industry, and government regulation of railroads (Hepburn Act, 1906)
  • Successes — raised the presidency's power and prestige; made regulation of big business politically acceptable; strengthened the US Navy and international standing
  • Failures — did not challenge racial segregation; his conservation and regulation went only as far as business interests would tolerate; critics said his reforms protected capitalism rather than changing it

Sir Wilfrid Laurier (Canadian prime minister, 1896–1911)

  • Political aims — hold together English and French Canada; promote national unity while respecting provincial and linguistic differences
  • Economic aims — encourage immigration to settle the Canadian prairies; build railways; industrialize through tariffs that protected Canadian manufacturing
  • Successes — presided over rapid growth: two new provinces (Alberta and Saskatchewan, 1905), a doubling of Canada's population through immigration, and construction of a second transcontinental railway
  • Failures — the 1911 election was lost partly over a proposed reciprocity (free-trade) deal with the US, which many English Canadians feared threatened ties to Britain; conscription and French–English tensions were never fully resolved and would resurface later
Choosing your Latin American leader: The syllabus lets you pick any one Latin American leader from this era — common choices are Porfirio Díaz (Mexico, before the 1910 revolution) or Julio Roca (Argentina). Whichever you choose, prepare the same three things examiners want for Roosevelt and Laurier: their political aims, their economic aims, and a balanced verdict on successes and failures.

One strong option for the 'one Latin American leader' bullet is Porfirio Díaz, who ruled Mexico almost continuously from 1876 to 1911. His era is known as the Porfiriato — a case study in how modernization could bring growth and repression at the same time.

1

Political aims

Díaz wanted order and stability after decades of civil war. His method was summed up as 'pan o palo' (bread or the stick) — reward allies with land and office, crush rivals with the army and police.

2

Economic aims

He wanted Mexico to modernize fast by attracting foreign investment, especially from the US and Britain, to build railroads, mines and oil wells.

3

Successes

Mexico's rail network grew from about 640 km to over 19,000 km; foreign capital poured in; exports of silver, henequen and oil boomed; Mexico City was rebuilt with modern boulevards and utilities.

4

Failures

Growth mainly benefited foreign investors and a small Mexican elite (cientificos). Peasants lost communal land (ejidos) to large haciendas; wages stagnated; political opposition was suppressed. This inequality is exactly what triggered the Mexican Revolution of 1910 (a later topic).

Díaz: order + foreign money in, land + rights out for the poor — modernization with a price.

What all three leaders shared

  • Wanted to modernize their economies (railways, trade, industry)
  • Balanced modernization against political unity or order
  • Left a mixed legacy of growth alongside unresolved tension

What made each different

  • Roosevelt regulated capitalism from within a stable democracy
  • Laurier managed a young federation split by language and religion
  • Díaz used authoritarian control, not democracy, to force growth
Why examiners love this comparison: A strong Paper 3 essay on 'leaders and modernization' does not just describe each leader — it compares their methods (democratic reform vs authoritarian control) and their results (durable institutions vs an era ending in revolution).

The syllabus also requires the social, economic and legal conditions of African Americans in this period — a story of new laws of oppression in the South, and new forms of resistance and culture across the whole country.

The New South and legal segregation

  • The New South — after Reconstruction ended in 1877, southern leaders promised industrial growth, but the economy stayed mostly agricultural and dependent on cheap Black labour through sharecropping and tenant farming
  • Black codes — laws passed right after the Civil War restricting Black Americans' rights to own property, move freely, or make contracts; these evolved into a fuller system of segregation
  • Jim Crow laws — state and local laws from the 1880s onward enforcing racial segregation in schools, transport, restaurants and public spaces across the South
  • Plessy v. Ferguson (1896) — the Supreme Court ruled that segregation was constitutional as long as facilities were 'separate but equal'; in practice, Black facilities were always underfunded and inferior, and this ruling legalized Jim Crow for almost 60 years
  • Disenfranchisement — poll taxes, literacy tests and 'grandfather clauses' stripped most Black men of the vote they had gained after the Civil War
LeaderCore ideaMethod
Booker T. WashingtonEconomic self-help first, political rights laterVocational education (Tuskegee Institute); the 1895 'Atlanta Compromise' speech accepted segregation short-term in exchange for economic opportunity
W. E. B. Du BoisFull and immediate civil and political rightsAcademic research and activism; co-founded the NAACP in 1909; argued for a 'Talented Tenth' of educated Black leaders
Marcus GarveyBlack pride, self-reliance and a return to AfricaFounded the UNIA; built Black-owned businesses; promoted Pan-Africanism and racial separatism
Three different tactics, one shared goal: Washington, Du Bois and Garvey disagreed sharply on method — accommodation, immediate legal equality, or Black separatism — but all three were responding to the same reality: a country that had legalized racial exclusion through Jim Crow and Plessy v. Ferguson.
