The revision or amending of existing articles of the confederation was the main reason for calling the constitutional convention of 1797. The Constitutional Convention (1797) which is also known as the Philadelphia Conference, or the Grand Conference of Philadelphia) took place in Philadelphia, Pennsylvania from 25 May to 14 September 14.
Though the aim of this Convention was to amend (making changes in the existing articles) the Articles of Confederation, many of its promoters (or advocates) wanted to build the new government instead of solving the issues of the existing one.
