America’s Founders set out to build a government entirely upon the will of the great body of the people. This had never been done before. And they set out to accomplish this across a great continent—George Washington’s army was strikingly called the Continental Army—despite the prevailing idea at the time that popular governments could only work in small areas. They succeeded in doing both these things, and the way they succeeded is contained in the American Constitution, the longest living and the greatest constitution ever written.
