The U.S. Department of Homeland Security (DHS) is a federal executive department established in response to the September 11, 2001, terrorist attacks, with the primary mission of protecting the United States from various threats, including terrorism, natural disasters, and other emergencies. Officially created in 2003, DHS coordinates and oversees a range of functions to enhance national security and ensure the safety of American citizens.
