Most accurate description of the federalist papers

The Federalist Papers was a collection of essays arguing the merits of the Constitution.

Explanation:

The Federalist Papers were a series of 85 articles published in various New York newspapers in 1787/88 that were intended to persuade the people of New York to approve the federal constitution of the United States, which was drafted but not yet ratified in 1787.  The authors of the articles were Alexander Hamilton, James Madison and John Jay, three of the founding fathers of the United States.

The Federalist Papers refers to the political grouping of federalists who advocated in the constitutional debate to transform the United States from a loose confederation into a state with a strong, capable executive at the federal level. Since this point of view finally prevailed, the Federalist Papers are still regarded as an authentic constitutional commentary of the generation of the founding fathers and, moreover, as a fundamental theoretical script of modern, representative democracy.
