Britain occupies an important position in modern history. When people go back to the long river of time and explore its roots, they all sigh: What a mess! Britain, the main island of England, has been inhabited for a long time. The inhabitants of the island created a splendid culture represented by the Stonehenge on the Saris Burry Plain in southern England 5,000 years ago. According to some historians' research, a nomadic clan group that lived in Central Asia about 1000 years ago split around 4000 BC, and the one that moved eastward entered Xinjiang, and then established various small kingdoms, such as Loulan in Han Dynasty. The one that moved south destroyed ancient India; One group that moved westward entered Iran, and the more famous ones were the ancient Persians and the Medes. It was the ancestors of the Germans who migrated north. Because Europeans have been in the leading position in the study of modern history for a long time, they have created historical terms centering on European geography and European history, so a large number of historical terms have European feelings, such as Asia Minor Peninsula, Palestinian periphery and East Asia, which are called "Near East", "Middle East" and "Far East" respectively according to their distance from Europe, while China, Korea and Japan are called "Mongolian race" because of the departure of Mongols. Similarly, they found that after the migration of ancient Central Asian nationalities, clan groups were called "ancient Indo-Europeans". They say this "India" because India is their model colony and they have feelings for it. They want all nations that resist colonial rule to learn from Indians, so they usually support India. In 2000- 1500 BC, Celts (called Gauls by the Romans), a branch of the ancient Indo-European language family, marched westward. In BC 1200- 1000, the Germans forced the Celts to continue westward to the British Island. Before they lived on the island, the Picts whose capital was Skan Palace were killed. Until 1296, King Edward I of England of England decided to change the ceremony to Westminster Abbey in London. Until the Norman Conquest, Scotland still owned the Kingdom of pickett. In 55 and 54 BC, Caesar led Roman troops on an expedition to the British Isles. After the Celtics surrendered, they retreated. In 43 A.D., the Romans established a province on the British Island, which was divided into two parts: the military area (mountainous area in the northwest) and the administrative area (plain area in the southeast). In fact, the Romans only controlled the administrative area, while Scotland in the north and Wales in the west were still in the hands of the Celts, who often rose up against Roman rule. In the 4th-5th century, the Roman Empire gradually declined and gradually gave up its control over Britain. The Romans withdrew their troops from 407 to 442, ending 400 years of British rule. After the Celtics gained political independence, they established many small principalities, which fought endlessly for territory, weakened their own strength and provided a good opportunity for foreign invasion. The Angles live in the southern part of jutland, the Jutes live in the northern part of the peninsula, and the Saxons live in the lower reaches of the Elbe River and the Weser River. They are all branches of the Germans. Angles and Saxons are closely related, and it is difficult to distinguish between language and customs. They were collectively called Anglo-Saxons in history. The Anglo-Saxons are the primitive tribes with the lowest romanization among the Moormans, and pirates have been harassing Britain since the third century. In order to guard against them, the Romans built forts and watchtowers along the southeast coast from Sollente to Wuxi, and equipped troops to deal with them. This area is called "Saxon Coast". Because the neighboring powerful Franks could not develop into Gaul, and the Romans had withdrawn their troops from Britain, they crossed the sea to Britain in the middle of the fifth century when the Huns marched westward. At this time, Utijilun, the leader of Celtic tribe in Kent, British Island, also asked Jutes to help them resist the pirate attacks of Picts and Squet. In 449, Heintges and Hausa, the military leaders of Jutes, led troops ashore from the Thames and entered Kent. Six years later, the two sides had a dispute over salary, and the Jutes occupied the Kent area by force and officially settled here. This is the first foreign invasion of Britain after the Roman evacuation. At the same time, the Saxons began to land in Davos Bay from the southeast coast of the North Sea and entered the Thames Valley. The Angles crossed the North Sea into central England. The Celts resisted these foreign peoples tenaciously, and the achievements of the Romans for hundreds of years were destroyed in the war. In 500 AD, the invasion was stopped due to the stubborn resistance of the Celts. A brave man named Arudill led the Celtics to clear the field and won great victories in succession, especially the victory of Barton Mountain, which stopped the invasion of Anglo-Saxons for decades. Before and after the Battle of Mount Barton, a branch of the Celts moved to Al Molik Peninsula to escape the war, hence the name Brittany (Little Britain). In 550, a new round of invasion began, and the Saxons in the south defeated the Celts and advanced into Bristol Bay. In 6 13, the Angles won a great victory in Chester, Nottinghamshire, and advanced to the Irish coast. These three peoples settled on the island. The Celts retreated to Wales, Scotland, Ireland and other places. At present, most residents in these three areas belong to Celtic descendants. In later generations, people from these three places immigrated to North America on a large scale and became the main force to develop North America. Now the proportion of Celtic descendants in the southern United States is quite high. The Anglo-Saxons successively established many small countries in the battle with the Celts, and after a long period of merger, they formed the Seven Kingdoms period in British history. At this time, the kingdom of Northumbria in the north, Mercia in the middle and Wessex in the south once ruled England, and the legend of King Arthur and the Knights of the Round Table happened in this period. Soon after the Anglo-Saxons finally settled in Britain after hundreds of years of hard struggle, they faced the invasion of other nationalities, this time the Normans. Norman (meaning northerner) is a branch of moorman, also known as Viking, which refers to Norwegians, Swedes and Danes living in Scandinavia and Midlands. 12677 I hope it will help you!
