the continued expansion of democratic government; 144 countries, representing two-third of the world's population, are full or partially democracies of same form. The Dutch Republic, also at war with Britain, was the next country after France to sign a treaty with the United States, on October 8, 1782. On April 3, 1783, Ambassador Extraordinary Gustaf Philip Creutz, representing King Gustav III of Sweden, and Benjamin Franklin, signed a Treaty of Amity and Commerce with the U.S. The Revolution had a strong, immediate influence in Great Britain, Ireland, the Netherlands, and France. Many British and Irish Whigs in Parliament spoke glowingly in favor of the American cause. In Ireland, the Protestant minority who controlled Ireland demanded self-rule. Under the leadership of Henry Grattan, the Irish Patriot Party forced the reversal of mercantilist prohibitions against trade with other British colonies. The King and his cabinet in London could not risk another rebellion on the American model, and so made a series of concessions to the Patriot faction in Dublin. Armed volunteer units of the Protestant Ascendancy were set up ostensibly to protect against an invasion from France. As had been in colonial America, so too in Ireland now the King no longer had a monopoly of lethal force. For many Europeans, such as the Marquis de Lafayette, who later were active during the era of the French Revolution, the American case along with the Dutch Revolt (end of the 16th century) and the 17th century English Civil War, was among the examples of overthrowing an old regime. The American Declaration of Independence influenced the French Declaration of the Rights of Man and of the Citizen of 1789. The spirit of the Declaration of Independence led to laws ending slavery in all the Northern states and the Northwest Territory, with New Jersey the last in 1804.

Status of African Americans During the revolution, the contradiction between the Patriots' professed ideals of liberty and the institution of slavery generated increased scrutiny of the latter. As early as 1764, the Boston Patriot leader James Otis, Jr. declared that all men, "white or black", were "by the law of nature" born free. Anti-slavery calls became more common in the early 1770s. In 1773, Benjamin Rush, the future signer of the Declaration of Independence,
