If we get a glimpse of the history of England from ancient to medieval times, we will find that it is a history of racial fusion. The country intercepted a new invader, fighting, defeated, and was finally ruled by the invader. The confrontation between the conqueror and the conquered continued, and then the country was invaded by other races again. There was a repetition of ethnic conflict and fusion, although it's the same island country as Japan, which had not been invaded by other races for more than 2000 years. Aside from that being good or bad,in Britain, individualism developed, industry developed, and literature flourished. Being prospered as a nation, England became the center of the British Empire with colonies all over the world. On the other hand, some people mainly living in northern England, got out of the country and headed for North America, eventually founding the United States. America has now become the leading nation of the world, whereas its homeland, England, is now a small country, whose glory as the former British Empire on which the sun never set, has faded. Still, England, the United Kingdom, affects the world, showing its new life-style, its new art,and its unique culture. The UK is driving the world politically, same as the USA. Many of the former colonial countires continue to use English as their official language. English spoken in various parts of the world is changing and developing independently over time, and sometimes it becomes far from the original English. However, nowadays, with the development of the Internet, a wide variety of English spoken in the world is beginning to settle down. In various countries, a number of writers whose novels written in English have won the Nobel Prize in Literature. While absorbing local words that deeply related to the identity of each country, English is steadily evolving as a global language. The essense of the English language is that it is simple and at the same time it can accurately convey complex and diverse content. Its plain expression that it is easy for everyone to understand is welcomed by many non-native speakers. The history of the English language is the history of human progress and it is also the history of the fusion of various racial groups with different values all over the world.
