Why is English the global language?

English is a modern lingua franca. It is a leading language in so many areas: from global affairs and science to entertainment. One of the reasons for that lies in the colonial history of the British Crown in the 17th century, when the British Empire became the biggest empire in history. With colonialism, trade relations boomed, following the progress in science, industrial manufacturing and literature. However, there were many other competing languages, such as French, Spanish and German.
