Federalist No. 7
Federalist No. 7, authored by Alexander Hamilton under the pen name Publius, is the seventh of 85 essays. Titled "The Same Subject Continued: Concerning Dangers from Dissensions Between the States", Hamilton warned against a dismemberment of state unity and the dangers that can arise over disputes over western lands. At that time western lands included the Great Lakes region and the Mississippi River.
Hamilton concludes the paper by expressing his belief that if the states are not brought together in a closer unity, that they would fall prey to the same wars and entanglements of their European brethren.
