Why did martin Luther king target Birmingham Alabama for a civil rights campaign?

Martin Luther King went to Birmingham Alabama because it was the most heavily segregated area at the time. He offered to put himself in jail assuming that other blacks would follow his example. Instead, blacks stayed home. After he got out of jail, he tried to see if any adults would also go to jail for this cause. NO adults stood up, but the children did. The children went to jail and ended segregation.
