Wednesday marks the 12th anniversary of the terrorist attacks of September 11, 2001. Memorial services will be held all across the country, many involving a reading of the victims' names.

Here’s a look at some  events that took place on this day in history: 1787: Delaware becomes the first state to ratify the United States Constitution (more info) 1941: In an early-morning sneak attack, Japanese warplanes bomb the U.S. naval base at Oahu Island's Pearl Harbor, causing the United States to enter World War II (more info)

In what's become a grim and somber ritual for Americans, citizens will gather Tuesday to mark the 11th anniversary of the 9/11 terror attacks, in which Islamic extremists killed nearly 3,000 people. Thousands are expected to come together in New York City, Washington, DC and Pennsylvania to pay their respects.
