At the time, the convention was not referred to as a "Constitutional convention", nor did most of the delegates arrive intending to draft a new constitution. Many assumed that the purpose of the convention was to discuss and draft improvements to the existing Articles of Confederation, and would not have agreed to participate otherwise. Once the convention began, however, most of the delegates – though not all – came to agree in general terms that the goal would be a new system of government, not simply a revised version of the Articles of Confederation.
