In the absolute monarchy the nation state law is determined solely through the royal prerogative : the monarch is the sole source of law and order. Political absolutism or autocracy are variant expressions of this absolute monarchical governance.
The constitutional monarchy is a dynasty of enfranchised governance, where the sovereignty of absolutism is relinquished to the democratic governance of the subject constituents.
In North America there remains the real estate land title dispute between the first settler "indigenous" Peoples and the rule of government through occupation and conquest.
The three nation states of Mexico, United States of America, and, Canada prevail today as nation states arising through conquest involving various forms of acquiescence and / or resignation by the first settlers of the circa 1100 sovereign independent traditional territories that had evolved throughout the period since the last major ice age period - some 30,000 years ago.
