Focus on the British, known around the world for their naval power, made an influential case for extending the reach of the American navy. Along with his publication of "Naval History", Carey wrote "Olive Branch", published in 1814. He tried to eliminate competition between the two American political parties to create unity during the War of 1812. To many people, these efforts, and his early relationship with Franklin, made him the logical choice as Franklin's political successor. Scholars believe that he contributed significantly by his books and publications to the establishment of the United States Whig Party.
