The Revolution had a strong, immediate influence in Great Britain, Ireland, the Netherlands, and France. Many British and Irish Whigs spoke glowingly in favor of the American cause. In Ireland, the Protestants who controlled Ireland demanded self-rule. Under the leadership of Henry Grattan, the so-called "Patriots" 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 made a series of concessions to the Patriot faction in Dublin. Armed Protestant volunteer units were set up to protect against an invasion from France. As in America, so too in Ireland the King no longer had a monopoly of lethal force.
