Prussian-American Treaty of Amity and Commerce

Prussian-American Treaty of Amity and Commerce

The Hague, 10 September 1785. MS (PCC, No. 135, I, f. 286–320). PRINTED: Miller, Treaties description begins Treaties and Other International Acts of the United States of America, ed. Hunter Miller, Washington, D.C., 1931–1948; 8 vols. description ends , 2:162–184. LbC (Adams Papers); APM Reel 111. The undated LbC was done by Charles Storer in early August from the copies brought to London by William Short on 3 Aug. for John Adams’ signature (to Thomas Jefferson, 4 Aug., above).

The Prussian-American treaty was concluded on the evening of 10 Sept. when Baron Friedrich Wilhelm von Thulemeier, the Prussian negotiator, signed two copies of the treaty at The Hague in the presence of C. W. F. Dumas and Short and delivered one of the copies to Short to be dispatched to America for ratification (commissioners’ 5 Aug. letter to Short, above; from Short, 11 Sept., below). The treaty had been signed by Benjamin Franklin at Passy on 9 July; by Jefferson at Paris on 28 July; and by Adams at London on 5 August. Prussia ratified the treaty on 24 Sept. 1785, and the United States did so on 17 May 1786.

The delay in the American ratification was owing to the fact that the treaty was enclosed in the commissioners’ letter to John Jay of [11 Oct. 1785], below, which apparently was not received until Feb. 1786, and Congress did not act until May because of its inability to assemble a quorum. The ratifications were exchanged at The Hague on 8 Aug. 1786 (Miller, Treaties description begins Treaties and Other International Acts of the United States of America, ed.
