What did Thoreau believe in in Civil disobedience?

Well, as you may know Thoreau was a Philosopher and transcendentalist. Thoreau believed in free thinking and self reliance. One thing Thoreau has done to act on his beliefs is he went to Walden Pond and built his own cabin and lived in solitude for two years. Also Thoreau didnt pay his taxes because he did not want to support a war in his time that he didn't believe was moral, so he was thrown in jail, inspired by this he wrote Civil Disobedience.
