Final answer:
The group that probably supported the Pinckney’s Treaty most was the 'White farmers in Kentucky'. This is due to the benefits it provided in terms of shipping and trade opportunities via the Mississippi River.
Step-by-step explanation:
The question is asking about the Pinckney’s Treaty or the Treaty of San Lorenzo in 1795. This treaty was an agreement between Spain and the United States that established boundaries and allowed the United States the right to navigate the Mississippi River freely. Considering the options, the group that was likely to be most supportive of the agreements made in this treaty are White farmers in Kentucky.
This is because the treaty improved the access and navigation rights of the Mississippi River, providing significant benefits to farmers located in areas like Kentucky. They were able to ship their products down the Mississippi River to New Orleans, and from there, transport their goods to East Coast markets. These new opportunities would have been highly appreciated by such farmer communities for their businesses and livelihoods.
