Why did Washington send Tomas Pinckney to Spain?

Answer 1

Washington sent Thomas Pinckney to Spain to negotiate a treaty regarding the use of the Mississippi River and the boundary between the United States and Spanish territories. The goal was to secure American access to the river for trade and to resolve tensions over territorial claims in the southeastern United States. This diplomatic mission aimed to strengthen relations with Spain and ensure the economic interests of the young nation were protected. Additionally, it was part of Washington's broader strategy to stabilize the country's foreign relations.
