Question

What is the MAIN reason that the author includes repeated flashbacks to the march in Selma?

Answer 1

The marches were organized by nonviolent activists to demonstrate the desire of African-American citizens to exercise their constitutional right to vote, in defiance of segregationist repression; they were part of a broader voting rights movement underway in Selma and throughout the American South.

After Jackson died of his wounds just over a week later in Selma, leaders called for a march to the state capital, Montgomery, to bring attention to the injustice of Jackson's death, the ongoing police violence, and the sweeping violations of African Americans' civil rights.
