What year did the World Trade Center collapse?

The World Trade Center collapsed on September 11, 2001, following a series of coordinated terrorist attacks carried out by al-Qaeda. This event is significant not only as a tragic loss of life but also as a turning point in global politics, security measures, and emergency preparedness. The attacks involved the hijacking of commercial airliners, two of which were flown into the Twin Towers, leading to their eventual collapse. The incident profoundly impacted New York City, the United States, and the world, leading to widespread changes in both domestic and international policy. The year 2001 is therefore crucial to understanding contemporary history, particularly regarding issues of terrorism, security, and urban rebuilding.
