He proposed that in this kind of government, it will do away with the tradition of 'monarchy,' likened to the British form of government, wherein powered is concentrated on one individual alone. Moreover, in advocating for the new American government, Madison argued that with the British ruling over the American people, the new government is a better option, the 'lesser evil' of the two: "[t]he bulk of the people will probably prefer the lesser evil of a partition of the Union into three more practicable and energetic Governments" (237). This argument in the letter was not an unfounded statement. Prior to declaring the new government as the better option for American society, Madison enumerated the numerous problems that emerged from the 'iron hand' that Britain used in ruling its colony (America). From his letter, the rising conflict between Americans and the British became apparent, and the external transition happened as a result of this conflict.

Internally, there was also a transition brewing, primarily between the African slaves and the members of the American colonies, who owned the slaves as 'properties.' In Max Farrand's discussion in "The Records of the Federal Convention of 1787 Slave...

During this time, the internal transition was already emerging, as different groups (specifically, Southern and Northern regions of the country) became divided and assumed different positions towards slavery in the country.
