All the latent spirit of freedom which had so long been slowly accumulating burst forth with a power which alarmed the court. Not a few of the nobles, disgusted with the aristocratic oppression which was ruining France, gave their sympathies to the American cause. The Marquis la Fayette, then but eighteen years of age, openly and enthusiastically applauded the struggle of the colonists. Marie Antoinette, instinctively hating a war in which the people were contending against royalty, expressed much indignation that La Fayette should utter such sentiments in the Palace of Versailles. Joseph II. of Austria, brother of Marie Antoinette, then on a visit to the French court, was asked by a lady his opinion of the subject which was now engrossing every mind. He replied, "I must decline answering; my business is to be a Royalist" (_Mon métier à moi c'est d'être Royaliste_).[48] It is hardly possible for one now to realize the enthusiasm with which the American war, at that time, inspired France. Even the court hated England, and wished to see that domineering power humbled. The mind of the nation had just awakened and was thoroughly aroused from the lethargy of ages. Theories, dreams, aspirations had exhausted themselves, and yet there was in France no scope whatever for action. America opened a theatre for heroic enterprise. France had given the theory of liberty, America was illustrating that theory by practice. The popular cry so effectually drowned every other voice that even the king was compelled to yield. A treaty with America was signed which drew from the treasury of France twelve hundred millions of francs ($240,000,000), in support of American independence.[49] But for the substantial aid thus rendered by the fleet and the army of France it can hardly be doubted that the American Revolution would have been crushed, Washington and Franklin would have been hanged as traitors, and monarchical historians would elegantly have described the horrors of the great American rebellion.[50] The king, however, had sufficient intelligence to appreciate the suicidal act he was thus compelled to perform. With extreme reluctance he signed the treaty which recognized the right of nations to change their government. The doctrine of the _sovereignty of the people_ was thus legitimated in France. That one sentiment unresisted would sweep Europe of its despotic thrones. As the king signed the treaty, Feb. 8, 1778, he remarked to his minister, "You will remember, sir, that this is contrary to my opinion."[51] The same weakness which constrained Louis XVI. to abandon Turgot to his enemies, compelled him to perform this act which his views of state policy condemned. "How painful," he writes, in his private correspondence, "to be obliged, for reasons of state, to sign orders and commence a great war contrary alike to my opinions and my wishes."[52]
