How did federalist papers make americans feel better about the constitution?

The Federalist Papers consist of eighty-five letters written to newspapers in the late 1780s to urge ratification of the U.S. Constitution. With the Constitution needing approval from nine of thirteen states, the press was inundated with letters about the controversial document. Celebrated statesmen Alexander Hamilton, James Madison and John Jay weighed in with a series of essays under the pseudonym “Publius,” arguing that the proposed system would preserve the Union and empower the federal government to act firmly and coherently in the national interest. These articles, written in the spirit both of propaganda and of logical argument, were published in book form as The Federalist in 1788. I hope that this helps you out
