Federalism in the United States
Many more Americans began to support federalism after Shays' Rebellion of 1786-1787.  Shays' Rebellion started out as a protest by poor farmers in western Massachusetts, and ended up as an armed rebellion.  Neither the federal government or the state government had enough soldiers or money to pay for an army that could stop the rebellion.  Merchants in Massachusetts had to pay for a private army to stop the rebellion.  Also, during the Rebellion, Massachusetts' state government took away people's right to habeas corpus (so they could keep people in jail without a trial) and their right to say bad things about the government.  Many Americans began to realize that under the Articles of Confederation, their government was unable to protect them or their rights.  This was not the republican government they had fought for.
