The failures of the articals and confederation led to what convention

The Philadelphia Convention.

Explanation:

The Philadelphia Convention, held in 1787, was a meeting between different political personalities from the Thirteen Colonies with the aim of modifying the Articles of Confederation, which had proven to be ineffective when organizing the political and social structure of the young nation. Ultimately, this convention ended up sanctioning the Constitution of the United States, since the Articles of Confederation proved to have too many shortcomings that required structural reform.
