Lysander Spooner's discontentment with the Constitution of the United States led him to publish No Treason, which revises significant parts of that document to reduce the power of the state versus individuals. The author was an anti-authoritarian philosopher and legal theorist who had spent his earlier life vigorously campaigning against slavery. Following the American Civil War however, he became horrified at the brutality and carnage that had been unleashed. Redoubling his criticisms, Spooner asserts his dismay that the U.S. government was rendered inert by its Constitution - slavery was only abolished after a long and bloody war, whereas had it been forbade at the outset, no such conflict would have arisen. A strong proponent of natural law - the concept that all humans had rights endowed at the point of their birth - Spooner had a sense of revulsion at how American politics had ensued in the early-to-mid 19th century.
