Convinced that the "victory of liberty over despotism" spelled an end to wars, the National Assembly [of France] resolved in May 1790 that the "French nation renounces the initiation of war for the purposes of conquest," and Victor Comte de Mirabeau, it's most influential early leader, proclaimed in August that "the moment is not far off when liberty will acquit mankind of the crime of war."
