The history of the English language can be traced back to before 100 BC when Celtic tribes inhabited Britain. In the 5th century AD, Germanic tribes invaded and introduced Old English. Old English was influenced by Viking invaders in the north. Between 1100-1450, Middle English developed as Norman French became the dominant language. Early Modern English emerged around 1470 with the introduction of the printing press. Latin had a strong influence on vocabulary. Since 1700, Late Modern English has become more standardized and similar to modern English with its widespread use globally.
