Andal Invasion

The second significant invasion that Westeros experienced was that of the Andals. The Andals from Essos arrived and took over as the dominant race on the continent after the First Men learned to coexist peacefully with the Children of the Forest. The Faith of the Seven, which the Andals introduced, gradually replaced the Old Gods of the First Men and the Children of the Forest as the predominant religion in the region.

The Andal Invasion, which takes place 6,000 years before the events of Game of Thrones, is comparable to the Saxon Invasion. The Andals abandoned their native realm of Northern Essos in order to elude the approaching Valyrian Freehold. The majority of people in Westeros have a mixture of Andal and First Men blood in them, therefore the Andals were able to conquer the region using a combination of cutting-edge military technology and strategic marital connections. The Andals, whose blood is more closely related to the First Men and whose culture is distinct from that of the other Seven Kingdoms, were unable to conquer the North.

Because one of the Germanic peoples who participated in the Saxon invasion was known as the Angles, the similarities are even more striking.
