Final answer:
Margaret Walker's "For My People" likely aimed to express personal experiences while critiquing the historical and political context of African-Americans.
Step-by-step explanation:
Margaret Walker most likely wrote the poem "For My People" to express her personal experiences and emotions as well as to critique the historical and political situations of African-Americans, particularly the injustices they faced. While the poem does not provide a factual account of a specific event, nor is it a fictional story, it serves to capture the collective experience and struggle of her people. Taking into account the broader context of African-American literature and history, Walker's poem resonates with the themes of identity, heritage, and the desire for liberation and equality, themes common in the work of other prominent Black writers of her era.
