Thomas Jefferson, President of the United States of America,
Reposing especial Trust and Confidence in Your Integrity, Prudence and Ability I have appointed Minister Plenipotentiary for the United States of America at the Court of His Britannic Majesty, authorizing you hereby to do and perform all such matters and things as to the said place or office do appertain … said office to Hold and exercise during the pleasure of the President of the United States for the time being, and until the end of the next Session of the Senate of the United States, and no longer.
Commission for Minister Plenipotentiary to Great Britain, 18 April 1803
Patrick Lee’s Explanation
A plenipotentiary possesses his leader’s full confidence.
To this blank form, President Jefferson added James Monroe’s name with full authority as ambassador to act on behalf of the United States. From an earlier post, we learned Monroe was dispatched to Europe to help negotiate American rights to free shipping down the Mississippi River and through New Orleans. In a time when round-trip communication between London or Paris and Washington, D.C. was at least two months, a trusted diplomat had to have the legal authority to act on his own.
That’s what plenipotentiary means, having full authority to act independently.
The President left no room for doubt about Monroe’s status. This blank form to the British Court was the first of six completed for him. Another was to the French Court, two to Napoleon, and one each to King George III and Queen Charlotte of Britain.
(While my 50 year old Webster’s Dictionary divides that 14 letter word into just five syllables, modern online versions give it seven!)
