In the turtle and birds story, does the turtle represent the colonizers and the birds the Igbo?
Am I correct to say that in the story about the turtle and the birds, the turtle can represent the white colonizers and the birds can represent the Igbo?
If so, what could I use as a thesis statement for an essay on that topic?
According to the analysis available at the following link, you are correct about what the story represents. Even the introduction of the tortoise is clearly indicating the European powers who heard of this feast in which they wanted to take part but weren't sure how to do it. They saw Africa as a new place to get raw materials and cheap labor and so descended upon it just as the tortoise found a way to rise into the air.
The tortoise used his great skill with language to trick the birds into giving him all the best things at the feast, just so the colonists find ways to convince the natives that they are going to be helpful and not harm the native customs, etc.
