The United States has operated under two constitutions. The first, The Articles of Confederation, was in effect from 
March 1, 1781, when Maryland ratified it. The second, The 
Constitution, replaced the Articles when it was ratified by New Hampshire 
on June 21, 1788.
The two documents have much in common – they were established by the same 
people (sometimes literally the same exact people, though mostly just in terms 
of contemporaries). But they differ more than they do resemble each other, 
when one looks at the details. Comparing them can give us insight into what 
the Framers found important in 1781, and what they changed their minds on by 
1788.
