In this poem, the speaker links himself to his ancestors, firmly placing them in important historical, religious, and cultural sites all over the world. The speaker begins by claiming a connection to the world's ancient rivers that predated human beings, and that has made his soul grow "deep like the rivers." This insightful and articulate description indicates the speaker's immense intellect, and allows him to make a definitive connection between people of his race and the rest of human civilization. In the early 20th Century, white Americans often viewed their darker-skinned counterparts as less than human, and here, Hughes offers concrete proof of historical equality.
The speaker mentions four great rivers, starting with the Euphrates, which historians and archaeologists often label as the birthplace of human civilization. Then, he mentions the strong and mighty Congo, along which many great African kingdoms have flourished. The speaker then cites the long, winding Nile and the great Egyptian pyramids. He witnessed the creation of these structures, which are amongst man's greatest feats of architecture. Finally, he writes about the muddy and golden Mississippi, which he links American slavery and Abraham Lincoln.
