June 30 [1785]. New York. Gardoqui to Floridablanca (confidential no I)
From 1785 to 1786, John Jay, as secretary for foreign affairs, negotiated with Spain concerning various boundary disputes with Spain’s North American territories. Chief among these issues was the right of American settlers to navigate the southern reaches of the Mississippi River, which passed through Spanish territory on its way to the sea. Spain had closed its portion of the Mississippi to American commerce in 1784; Congress specifically instructed Jay that any treaty with Spain had to win back that right. Spain’s ambassador, Don Diego de Gardoqui, refused to accede to this demand out of Spanish fears of America’s westward expansion.
