Travian is an online browser game wherein the player takes on the role of a Roman, a Gaul, or a Teuton, and starts as a village chief and tries to build the village as large as they can.

When the Romans left England, this land was settled mainly by teutons, who lived in the German district of Angeln, and Saxons, from another German region. Hence the name Anglo-Saxon. The Teuton, because of their native region, received the name "angles".

It's not a poem but a passage in W.E.B. DuBois's essay "Of Our Spiritual Strivings," Chapter One in The Souls of Black Folk. The essay may also have been published elsewhere.
