During the Birmingham campaign of 1963, which action by authorities escalated tensions against protesters?

• A. Dogs were set on protesters
• B. JFK mediated the negotiations
• C. The city desegregated parks
• D. The NAACP leader in Mississippi was shot

Answer: (A)

The action that most clearly escalated tensions was authorities using police dogs against the protesters. In Birmingham in 1963, nonviolent demonstrators faced aggressive responses from local officials, and images of dogs cornersing or attacking marchers—often alongside high-pressure hoses—made the brutality widely visible. This kind of forceful response shifted public perception, drew national sympathy for the civil rights cause, and increased pressure for federal action. The other options don’t fit the moment: the campaign did not hinge on JFK mediating negotiations, and desegregating parks or a separate assassination in Mississippi aren’t what sparked the escalation in Birmingham.
