The two issues or events that highlighted the insufficiency of the power of the central government under the Articles of Confederation are:
-
The rebellion of farmers in Massachusetts due to an increase in taxes - This refers to Shays' Rebellion, which demonstrated the weaknesses of the Articles in addressing economic distress and maintaining order.
-
The central government’s inability to impose taxes on states - This was a fundamental weakness of the Articles of Confederation, as the federal government had no power to tax, which hampered its ability to raise revenue and support a national army or public services.
These two points clearly illustrate the failures of the Articles of Confederation and the need for a stronger central government.
