Thomas Jefferson had bitterly opposed the Jay Treaty because he feared it would strengthen anti-republican political enemies. When Jefferson became president in 1801, he did not repudiate the treaty. He kept the Federalist minister, Rufus King in London to negotiate a successful resolution to outstanding issues regarding cash payments and boundaries. The amity broke down in 1805, as relations turned increasingly hostile as a prelude to the War of 1812. Jefferson rejected a renewal of the Jay Treaty in the Monroe–Pinkney Treaty of 1806 as negotiated by his diplomats and agreed to by London; he never sent it to the Senate.
