An interesting tidbit in these times: according to Richard Morriss' book Witnesses at the Creation, one of the reasons John Jay (one of the Federalist writers) pushed for the adoption of a stronger central government to replace the Articles of Confederation was the inability of the Confederation government to respond to the attacks by the Barbary pirates. These pirates were North African Muslims who justified their attacks as strikes against the infidels. So indirectly Islam helped prompt us to adopt our present Constitution.
