However, the Angle, Saxon and Jute branches of the Germanic raids in the Tribal Hidage that reached Britain soon began to spread on the island. These nation who settled in the lands which they conquered from Britons were called as Anglo-Saxons because of their union of fate, left their old beliefs within a few centuries and converted to Christianity.

The Heptarchy order established by Anglo-Saxons' which has any other example in history and their efforts to seize power in this order are the main factors in their internal struggles. The Kingdom of Mercia, one of the most important states of the Heptarchy order, has been the main actor of this order for many years.
