What Else Happened on the Fourth of July?

How important is the Fourth of July to Americans? Important enough that most people call it by its date rather than its name. July 4, 1776, marks the signing of the Declaration of Independence, but the date has echoed through history in ways that reach far beyond fireworks and parades. Here are some of the most surprising moments that also happened on America’s birthday.

Two Founding Fathers Died on the Same Day

A Murder That Inspired a TV Classic
