After the Romans withdrew, the Angles, Saxons, and Jutes in northern Europe invaded and settled one after another.

In the 7th century, the feudal system began to form, and many small states were merged into seven kingdoms, which lasted for 200 years, and the history is known as the "Anglo-Saxon era".

In 829, King Egbert of Wessex united England. It was invaded by the Danes at the end of the 8th century and was part of the Danish pirate empire from 1016 to 1042. After a short period of English rule, the Duke of Normandy crossed the sea to conquer England in 1066.

The 19th century was the heyday of the British Empire, and in 1914 it occupied a colony 111 times larger than the mainland, making it the first colonial power and calling itself the "empire on which the sun never sets". After the First World War, it began to decay.

Britain established the County of North Irand in 1920 and allowed the south of Ireland to secede from its rule in 1921-1922 as an independent state.

In 1931, the Act of Westminster was enacted, forcing the Dominion to recognize its independence in domestic and foreign affairs, and the colonial system of the British Empire was shaken ever since.

Year 1688.

The Glorious Revolution of 1688 established a constitutional monarchy, and from the 60s of the 18th century to the 30s of the 19th century, it became the first country in the world to complete the industrial revolution, and its national power grew rapidly. From the 18th century to the early 20th century, Britain ruled the territory across seven continents of the world, and was the most powerful country and the largest colonial empire in the world at that time, with a colonial area equal to 111 times the size of the mainland, known as the empire on which the sun never sets.
