Du Pont engaged in informal diplomacy between the United States and France during the reign of Napoleon. He was the originator of an idea that eventually became the Louisiana Purchase, as a way to avoid French troops landing in New Orleans, and possibly sparking armed conflict with U.S. forces.[citation needed] Eventually, he settled in the U.S. permanently; he died there in 1817.[citation needed]
