The Federalist Papers were a series of eighty five essays published in major New York newspapers to urge ratification of the new Constitution of the United States by New York. It was believed that the government created by the constitution would not be workable if New York were not a member of the government. All the essays were signed with the pseudonym, Publius ("for the public.") Scholars are in agreement that the true authors were Alexander Hamilton who wrote 51 articles; James Madison, who wrote 26; and John Jay, who wrote five. Three (numbers 18 through 20) were a joint effort between Madison and Hamilton.
The Federalist Papers have long been considered an important source to determine the intent of the framers of the Constitution, and are often cited by Constitutional scholars to that effect. Because New York did ratify the Constitution, and because the Federalist Papers are still relied upon to determine the intent of those who drafted the constitution, it is safe to say that the authors succeeded beyond their wildest dreams.
Alexander Hamilton and James Madison wrote the Federalists papers. It was to support the constitution. Therfores, they did succeed.
