35 Colonies, 400 Years: How One Empire Made Half the World Speak Spanish
Spanning over four centuries, the Spanish Empire expanded across the Americas, Asia, Africa, and Europe, colonising 35 territories. Through exploration and trade, Spain established a vast global domain before these nations gradually achieved their independence.
Key Points
- Spanish speakers grew from <4M in 1492 to over 500M today, surpassing English.
- The Spanish Empire spanned four centuries, peaking under Philip II, uniting thrones in 1580.
- The empire's reach across continents shaped global trade, with Potosí silver as world currency.
In 1492, when Columbus sailed to the west, the number of Spanish-speaking people in the world stood at less than 4 million. In fact, it was not even the only language in the Iberian Peninsula. It was just Castilian – just another dialect fighting for supremacy in the newly created state of Spain.
Four centuries later, that one small dialect has come to conquer half a continent, cross three oceans and destroy many other languages.
Now, Spanish is spoken by over 500 million people in 35 countries and boasts an extra 100 million speakers compared to English.
But then again, how could a language which came from caves in northern Spain create a linguistic empire that survived even when its empire had long since fallen?

About the Spanish Empire
The Spanish Empire, which has been referred to throughout history as the Monarchia Hispanica (Hispanic Monarchy) and the Catholic Monarchy (Monarquía Católica), is one of the greatest empires of all time in geographical terms.
The era of Philip II's reign is the era of the peak of the Spanish Empire and its achievement of the fame of being "an empire where the sun never sets".
Over the course of four centuries of its existence, the Spanish Empire included not only European countries but also the territories of North and South Americas, Africa, the Philippines and some territories of Asia.
In 1580, Philip II managed to unify the Spanish and Portuguese thrones and dominated their vast trade network for sixty years.
In addition to colonisation and mining of metals, the Spanish Empire changed the economy and culture of the planet in many different ways. For example, silver extracted in Potosí (currently in Bolivia) used to be the leading currency of the world, even in the trade between Spain and Imperial China.
Besides that, through the Columbian exchange, the Spanish Empire changed the food habits and farming practices of the globe.
