Where did English originate?

Early Germanic tribes (Angles, Saxons, Jutes and Frisians) immigrated to England, and English was inherited from their language variations. According to the "Anglo Saxon Chronicle", around 449 AD, Vortigern, king of the British Isles, invited "Anglo relatives" to help him fight against the Picts. In return, he granted the Angles territory in the southeast. He then sought further support, and Saxons, Angles, and Jutes came one after another. "Chronicles" records that these "immigrants" eventually established seven kingdoms: Northumbria, Mercia, East Anglia, Kent, Essex, Sussex, and Wessex. After the Germanic invasion, they dominated the local Celtic-speaking peoples, and the local languages ??survived mainly in Scotland, Wales, Cornwall and Ireland. The language of these invaders gradually formed "Old English", which is very similar to modern Frisian. The three words English, England and East Anglia are respectively developed from the words describing the Anglo people: Englisc, Angelcynn, Englaland. For three hundred years after the Norman Conquest in 1066, the kings of England spoke only French. As a result, a large number of French words entered Old English, and Old English itself lost most of its twists and turns, evolving into Middle English. The great vowel shift around 1500 transformed Middle English into Modern English. The most famous literary work in Old English is "Beowulf" and in Middle English is "The Canterbury Tales". Modern English began to flourish during Shakespeare's period. Some scholars divide it into early modern English and late modern English, with the dividing line being around 1800. As Britain occupied and colonized much of the world, local languages ??also greatly influenced the development of English.
