Thoreau's actions in "Civil Disobedience" are very similar to those of the bus boycott because they both wanted to protest injustices of the American government. In the case of Thoreau, he refused to pay taxes in order to protest the government's involvement in wars and their inefficiency in addressing other injustices. In the case of the boycott, the protest was directed towards racial segregation. In both cases, the protestors expressed their grievances in peaceful ways.
