John Trumbull (Mifflin standing at left), 23 December 1783. Prior to American independence, Mifflin was a member of the
Pennsylvania Provincial Assembly (1772–1776). He served two terms in the Continental Congress (1774–1775 and 1782–1784), including seven months (November 1783 to June 1784) as that body's presiding officer. Mifflin's most important duty as president was to accept on behalf of Congress the
resignation of General George Washington on December 23, 1783. After the war, the importance of Congress declined so precipitously that Mifflin found it difficult to convince the states to send enough delegates to Congress to ratify the
Treaty of Paris, which finally took place on January 14, 1784, at the
Maryland State House in Annapolis. He also appointed
Thomas Jefferson as a minister to France on May 7, 1784, and he appointed his former aide, Colonel
Josiah Harmar, to be the commander of the
First American Regiment. Mifflin later served as a delegate to the United States Constitutional Convention in 1787. He was a signatory to the Continental Association and the Constitution. He presided over the committee that wrote
Pennsylvania's 1790 state constitution. That document did away with the Executive Council, replacing it with a single governor. On December 21, 1790, Mifflin became the last president of Pennsylvania and the first governor of the Commonwealth. He held the latter office until December 17, 1799, when he was succeeded by
Thomas McKean. The
Whiskey Rebellion and the
1793 Philadelphia yellow fever epidemic happened during his term in office.
Fries Rebellion also started during his term. He then returned to the state legislature, where he served until his death the following month. == Personal life ==
