When the pressure of European affairs mounted during 1795, Spain’s Minister of State, the erratic Manuel de Godoy, was persuaded to sign the Treaty of San Lorenzo (Pinckney Treaty) with the United States in an effort to neutralize that power in the approaching struggle with the English. Whatever its utility to Spain in Europe, this treaty marked the beginning of the end for Spain’s North American empire by yielding control over the Mississippi and by surrendering the strategic posts north of the thirty-first parallel and east of the Mississippi.
