America’s Civil War became part of a much larger international crisis as European powers, happy to see the experiment in self-government fail in America’s “Great Republic,” took advantage of the situation to reclaim former colonies in the Caribbean and establish a European monarchy in Mexico. Overseas, in addition to their formal diplomatic appeals to European governments, both sides also experimented with public diplomacy campaigns to influence public opinion. Confederate foreign policy sought to win recognition and aid from Europe by offering free trade in cotton and aligning their cause with that of the aristocratic anti-democratic governing classes of Europe. The Union, instead, appealed to liberal, republican sentiment abroad by depicting the war as a trial of democratic government and embracing emancipation of the slaves. The Union victory led to the withdrawal of European empires from the New World: Spain from Santo Domingo, France from Mexico, Russia from Alaska, and Britain from Canada, and the destruction of slavery in the United States hastened its end in Puerto Rico, Cuba, and Brazil.
