Here's a short story:

English is a West Germanic language that was first spoken in early medieval England and is now a global "lingua franca". Named after the Angles, one of the Germanic tribes that migrated to England, it ultimately derives its name from the Anglia (Angeln) peninsula in the Baltic Sea. It is closely related to the Frisian languages, but its vocabulary has been significantly influenced by other Germanic languages, particularly Norse (a North Germanic language), as well as by Latin and Romance languages, particularly French. 

English has developed over the course of more than 1,400 years. The earliest forms of English, a set of Anglo-Frisian dialects brought to Great Britain by Anglo-Saxon settlers in the 5th century, are called Old English. Middle English began in the late 11th century with the Norman conquest of England, and was a period in which the language was influenced by French. Early Modern English began in the late 15th century with the introduction of the printing press to London and the King James Bible, and the start of the Great Vowel Shift. Through the worldwide influence of the British Empire, modern English spread around the world from the 17th to mid-20th centuries. Through all types of printed and electronic media, as well as the emergence of the United States as a global superpower, English has become the leading language of international discourse and the "lingua franca" in many regions and in professional contexts such as science, navigation and law.
