What were the reasons for the federalist papers?

In the Federalist Papers, Hamilton, Jay and Madison argued that the decentralization of power that existed under the Articles of Confederation prevented the new nation from becoming strong enough to compete on the world stage, or to quell internal insurrections such as Shays's Rebellion. In addition to laying out the many ways in which they believed the Articles of Confederation didn't work, Hamilton, Jay and Madison used the Federalist essays to explain key provisions of the proposed Constitution, as well as the nature of the republican form of government.
