On September 11, 2001, hijacked planes crashed into the Twin Towers and changed the United States forever.

Few events in American history have impacted the nation the way these terror attacks did. And twenty-five years later, the United States continues to feel those impacts. But what all happened on September 11? And what followed?

From efforts to support a mourning nation and rebuild the World Trade Center to new wars facing mixed support to economic downturns and a rise in discrimination and surveillance, After the Towers Fell breaks down the day of the attacks and the effects that followed. It examines both the immediate aftershocks and the slower changes that came in the weeks, months, and years after. It is difficult to perfectly quantify the role September 11 played in shaping the United States we know now. But one thing is undeniable: Social life, politics, economics, infrastructure, and more have never been the same since.
