Melish’s comments on his 1816 map of the United States

“To present a picture of it was desirable in every point of view. The map so constructed, shows at a glance the whole extent of the United States territory from sea to sea; and in tracing the probable expansion of the human race from east to west, the mind finds an agreeable resting place on its western limits. The view is complete, and leaves nothing to be wished for. It also adds to the beauty and symmetry [balance] of the map; which will, it is confidently believed, be found one of the most useful and ornamental [decorative] works ever executed [created] in this country.” –John Melish, 1816

What do you think?• This theory that Americans are special is called

“American Exceptionalism.” It’s this idea that America has had such a unique history and has become so powerful that there’s something really special about it.

• What do you think about this theory? What do you predict this belief will lead to as we go through U.S. History?
