The correct answer is:
It was a blueprint for methods of nonviolent protest.
Explanation:
Thoreau wrote Civil Disobedience in 1849, during slavery issues and the Mexican-American war, the night after he was imprisoned in Concord, Massachusetts for refusing to pay his taxes.
In his essay he stated that the government was unfair, and that democracy only favored the majority. He also stated that people should follow their conscience first, and the laws later. Thoreau refused to pay his taxes as part of the Civil Disobedience, because the Mexican American war would lead to expansion of slavery, and Thoreau disagreed. This fact created an impact on Martin Luther King Jr, he expressed in his autobiography that Thoreau had inspired him because he was the pioneer of nonviolent methods to protest against the government.
<em>Martin Luther King Jr., also wrote his essay A letter from Birmingham jail, after being imprisoned for the protests in Birmingham, Alabama, and talked about nonviolent protests, and the frustration towards white moderators. This fact also shows Thoreau's influence over Martin Luther King Jr. </em>
