So, what was the reason for the Angles under Eomaer to evacuate Angeln and go to Britain? Pressure from other tribes or something else?
The mass migration, and that is what seems to have happened, could have been caused by a number of factors. Authun mentioned one such reason. There was a down turn in the climate at that time, and there were the marine transgression which must have had a adverse effect on the coastal regions of Angeln. Environmental stress can cause a desperate people to mass migration and this has, indeed, happened throughout history. Political pressure too can lead to mass migration as we in Europe have seen only to tragically recently, and there was such political stress at this time with the Huns. All of these reasons can be called the "push factors". Then we have in the fifth century, a pull factor, and this was the breakdown of political authority in Britain when the Romans left. A golden opportunity for these early English to take advantage of the situation.
If you need further information on the prevailing climatic conditions around the North Sea littoral, in particularly the marine transgressions, Authun is the man.
