The Federalists favored ratification of the United States Constitution because they believed that the U.S. would not survive unless the Constitution was passed. They also argued that a stronger national government was needed after the Articles of Confederation failed. The ratification would split the government into three equal branches, which the Federalists believed would reduce the chances of tyranny.
In order for the U.S. Constitution to be passed, which was written in 1787 at the Philadelphia Constitutional Convention, nine out of 13 states would have to vote before the Constitution could be passed. The Federalists succeeded, with the Constitution being ratified in 1788 and then put into effect in 1789. Federalism is a type of government that divides power between the state governments and national governments.
