Pulitzer Prize History Winner

Pinckney's Treaty

by Samuel Flagg Bemis

Summary

Bemis reconstructs the diplomacy behind the 1795 treaty with Spain that opened the Mississippi River and the port of New Orleans to American commerce and fixed the southern boundary. Using archives across several countries, he shows how European rivalries and shrewd negotiation served young American interests. The study became a model of careful diplomatic history.

Bemis won a second Pulitzer Prize for History in 1950 for his biography of John Quincy Adams.
