Why were places such as georgia and alabama considered as "ground zero" for the american civil rights movement? include specific examples and instances of the civil rights movement

In this case, "ground zero" means the starting point for an activity (like the American Civil Rights Movement). Georgia and Alabama were considered the starting points for this movement due to events such as the Montgomery Bus Boycott (after Rosa Parks refused to give up her seat to a white man) and the campaign to end segregation in Albany, Georgia. These events began the domino effect for the Civil Rights Movement, inspiring other protests and demonstrations to occur across the country.
