Thoreau's definition of civil disobedience?

Question

What did Thoreau define as civil disobedience?

Answer 1

He believed that---government is best that governs the least.

My own thought is that Ghandi and Martin Luther King was the Kings of civil disobedience.

Answer 2

People should not permit governments to overrule or atrophy their consciences, and that people have a duty to avoid allowing such acquiescence to enable the government to make them the agents of injustice. Thoreau was motivated in part by his disgust with slavery and the Mexican-American War.
