Why English, French, Spanish, and Portuguese Spread Across the World

by
An 1886 world map showing the extent of the British Empire coloured pink.

About 1.5 billion people speak English, most as a second language; French, Spanish, and Portuguese are official across three continents. Four different mechanisms carried them there — replacement, administration, the mission school, and a choice made at independence — and Indonesia and Tanzania show what the alternative looked like.

Did Colonialism Develop Africa — or Build Systems for Extraction?

by
A 1907 photograph of the Matadi to Stanley Pool railway, built to carry exports to the coast.

Colonial rule built railways, ports, and schools across Africa — and designed the railways to run from mine to port, not region to region. Separating ‘were things built?’ from ‘what were they built for?’, and what the economic-history evidence says about the net effect.

African Kingdoms and the Slave Trade: Agency, Coercion, and the Danger of Simple Narratives

The transatlantic trade ran on purchase, not seizure, and African states and merchants managed its African end. That is a fact, and it settles less than people expect. Dahomey, Asante, Oyo, Kongo; the Rodney-Thornton debate; and why ‘Africans did it too’ does not do the work it is asked to.

Who Profited from the Slave Trade? Following the Money Across the Atlantic

by
Herman Moll's 1711 map of the region covered by the South Sea Company's slave-trading contract.

When Britain abolished slavery it paid £20 million to the owners and nothing to the enslaved. But the profit of the slave economy ran through a much longer chain — ships, insurers, banks, refiners, the state, consumers. Following the money, and where it can still be found.

Andries Beeckman's painting of the Dutch East India Company headquarters at Batavia.

Chartered in 1602 with the right to wage war, coin money, and execute people, the VOC was the first modern corporation and, for two centuries, a sovereign power with shareholders. Its financial innovations built the stock market; its monopoly strategy produced a genocide.

The Congo Free State: When a Colony Became a Private Extraction Machine

A 1906 map of the revenue divisions of the Congo Free State, private colony of Leopold II.

For twenty-three years a territory eighty times the size of Belgium was one man’s private property, run for rubber through a quota system enforced by hostage-taking, the whip, and severed hands. How it worked, how it was exposed, and why the death toll is still disputed.

Sugar: The Crop That Built Fortunes and Destroyed Lives

by
William Clark's 1823 aquatint of a sugar-plantation mill yard in Antigua with enslaved workers.

A luxury became a working-class staple in a century, produced by a labour system so lethal the enslaved population could only be maintained by constant imports. How sugar drove Atlantic slavery, prefigured the factory, and left its mark from the teacup to the clinic.

The Columbian Exchange: The Biological Revolution That Created the Modern World

A botanical illustration of maize, a staple crop carried worldwide in the Columbian Exchange.

The transfer of crops, animals, and diseases between the Americas and the rest of the world after 1492 reshaped diets, populations, and landscapes on every continent — and in places mattered more than any treaty. How it worked, and why it was never a fair exchange.
