Did the department of homeland security create other departments?

Yes, the Department of Homeland Security (DHS), established in 2003, consolidated several federal agencies and functions related to national security and emergency management. While DHS itself did not create entirely new departments, it did integrate existing agencies such as the Coast Guard, the Federal Emergency Management Agency (FEMA), and the Transportation Security Administration (TSA) into its structure. Additionally, DHS has the authority to create new divisions and offices to address emerging threats and challenges in homeland security.
