1.2 The Spread of English

How English Conquered the World

Picture a Norwegian engineer, a Brazilian designer, and a Japanese manager meeting at a conference in Dubai. None of them shares a native language, yet they talk effortlessly. The language they reach for is, almost certainly, English. How did this happen? How did a language from a small, rainy island in the North Atlantic become the common tongue of the entire planet?

Today roughly 1.5 billion people speak English -- but only about 400 million of them are native speakers. The other 1.1 billion learned it as a second or foreign language. That ratio is the key to the whole story. English did not spread because it is somehow a "better" or "easier" language than others. It spread because of power -- two great waves of it. The first was British colonial expansion from the 17th to the 20th centuries, which physically planted English around the globe. The second was American global dominance in the 20th and 21st centuries, which made English the language of money, technology, science, and entertainment. Add the rise of the internet on top of these waves, and you have a language unlike any that has come before.

The First Wave: The British Empire

At its height, the British Empire governed nearly a quarter of the world's land and about a fifth of its people. Wherever British power went, the English language went too -- but it spread in different ways depending on the type of colony.

In settler colonies such as the USA, Canada, Australia, New Zealand, and South Africa, large numbers of English speakers migrated and made English the dominant language, often displacing or marginalising indigenous languages. In exploitation colonies such as India, Nigeria, Kenya, Singapore, and Hong Kong, a smaller number of British administrators used English as the language of government and education, layering it on top of existing languages and creating bilingual or multilingual societies. In trading posts across West Africa, Southeast Asia, and the Middle East, English served mainly commercial purposes.

The legacy was enormous. Over fifty countries ended up with English as an official or co-official language. English-medium education became a path to social mobility, and -- crucially -- after independence, many nations chose to keep English. India is the classic example. Britain ruled India for nearly two hundred years, and in 1835 Thomas Macaulay's "Minute on Education" made English the medium of higher education. After independence in 1947, India kept English for very practical reasons: with 22 official languages, English was a neutral link language that did not favour any one ethnic group (when Hindi was proposed as the sole national language, southern states protested fiercely). English also opened the door to the global economy -- India's IT sector, worth over 200 billion dollars, runs largely in English. Today India has the second-largest number of English speakers in the world.

The Second Wave: American Power and the Global Default

If the British Empire planted English around the world, American global dominance turned it into the default language of international life. American power flowed through many channels at once.

Economically, the US dollar became the world's reserve currency, and American companies -- Apple, Google, Amazon, Microsoft -- came to dominate global markets. Culturally, the United States exercised enormous soft power: the ability to influence others not through force but through the appeal of its culture. Hollywood produced the world's most widely distributed films; American pop, hip-hop, and rock topped global charts; American TV streamed worldwide through Netflix, HBO, and Disney+; and social media platforms like Instagram, YouTube, and TikTok operated primarily in English. In science and technology, over 80 percent of academic journals are published in English, the internet was invented in the USA and began entirely in English, and programming languages use English keywords. In higher education, American universities dominate global rankings and increasingly teach in English to attract international students.

The result of all this is profound: learning English is no longer seen as learning someone else's language. It has become an essential skill for taking part in the modern world. English now holds a special role in business (the working language of most multinationals), in science (publish in English or risk being overlooked), in technology (the internet still holds roughly 60 percent of its content in English), and even in safety-critical fields -- it is the mandatory language of international air traffic control, set by the ICAO, and the standard language of maritime communication. For a Norwegian student, English is woven into nearly every part of daily life: streaming, gaming, social media, school, and future work.

Summary

English became the world's lingua franca through two great waves of power. The first was British colonial expansion, which physically planted English across settler colonies, exploitation colonies, and trading posts, leaving over fifty countries with English as an official language -- and giving newly independent nations like India a neutral link language they chose to keep. The second wave was American global dominance, which made English the default language of business, science, technology, and entertainment through economic might and cultural soft power. Roughly 1.5 billion people now use English, most of them non-native speakers. The crucial lesson is that English did not triumph because it is a superior language; it triumphed because the nations that spoke it held extraordinary political, economic, and cultural power. Understanding this helps us think critically about what English dominance means for the world's other languages.
