Originally planned to begin on May 14, the convention had to be postponed when very few of the selected delegates were present on that day due to the difficulty of travel in the late 18th century. On May 14, only delegates from Virginia and Pennsylvania were present. It was not until May 25 that a quorum of seven states was secured and the convention could begin inside the Pennsylvania State House. New Hampshire delegates would not join the convention until July 23, more than halfway through the proceedings.
