Question: to what extent did the federalist era leave the united states a stronger nation

title: Federalist Era
text: During the 1780s , Spain had sought to slow the expansion of the U.S. and lure American settlers into secession from the United States . Washington feared that Spain ( as well as Britain ) might successfully incite insurrection against the U.S. if he failed to open trade on the Mississippi , and he sent envoy Thomas Pinckney to Spain with that goal in mind . Fearing that the United States and Great Britain might unite to take Spanish territory , Spain decided to seek accommodation with the United States . The two parties signed the Treaty of San Lorenzo in 1795 , establishing intentions of friendship between the United States and Spain . The United States and Spain agreed not to incite native tribes to warfare . The western boundary of the United States was established along the Mississippi River from the northern boundary of the United States to the 31st degree north latitude , while the southern boundary of the United States was established on the 31st parallel north . The disputed territory that Spain dropped its claims to would be organized into the Mississippi Territory in 1798 .
