What did the Declaration declare? An enduring mythology has grown up around the creation of the Declaration of Independence. Generations of Americans believe that Jefferson wrote it in his Philadelphia study, influenced only by the stirring of great events around him. Challenging this romantic ideal, the five historians included here find that the document was the result of many influences and that it may have even been a collaborative writing effort on the congressional floor. Investigating various angles of the argument, the authors pose a variety of opinions on the Declaration's authorship, influences, and ultimate impact.
Joseph John-Michael Ellis III is an American historian whose work focuses on the lives and times of the Founding Fathers of the United States. His book American Sphinx: The Character of Thomas Jefferson won a National Book Award in 1997 and Founding Brothers: The Revolutionary Generation won the 2001 Pulitzer Prize for History. Both of these books were bestsellers.
This is a good Introduction to some of the arguments about the Declaration. Though you really should read the actual books these chapters are taken from.
