What event prompted the calling of the Philadelphia Convention?

The event that prompted the calling of the Philadelphia Convention was the Annapolis Convention. This gathering took place in 1786, where delegates from five states convened to discuss issues related to interstate trade and commerce, highlighting the weaknesses of the Articles of Confederation. The shortcomings in governance became increasingly apparent, and it was at the Annapolis Convention that the need for a broader constitutional reform was recognized. Delegates concluded that a more substantial strategy was necessary to address the various economic and political challenges faced by the nation.

Following this convention, a call was made for a second meeting in Philadelphia to draft a new constitution, leading to the historic Philadelphia Convention in 1787. This convention resulted in the formation of the United States Constitution, replacing the Articles of Confederation and creating a stronger federal government. The significance of the Annapolis Convention in galvanizing efforts for reform marks it as a pivotal event in the lead-up to the Philadelphia Convention.
