Answer:
The Constitutional Convention of Philadelphia took place between May 14 and September 17, 1787. In it, a total of 55 delegates from 12 of the 13 Original Colonies (only Rhode Island is missing) met to discuss changes to the Articles of Confederation, which were in question after a series of social revolts and the demonstrated inability of the central government to regulate trade and economy.
During the Convention, the delegates moved from a position aimed at modifying the Articles of Confederation to a desire to create a new maximum law for the United States, which politically organized the country efficiently and without giving place to the economic and social problems that the Articles had indirectly generated. Thus, the Constitution of the United States was sanctioned on September 17, 1787.
