In the United States, the authority to activate the National Guard depends on the status under which the Guard is being activated. Authority: Governor of the respective state or territory.
Here’s a breakdown:
🟢 State Activation (Title 32 or State Active Duty)
Authority: Governor of the respective state or territory
Use: Natural disasters, civil disturbances, emergencies (e.g., hurricanes, wildfires, protests)
Command: The Guard remains under state control
Funding:
State Active Duty: State-funded
Title 32: Federally funded but still under state control
âś… Example: A governor activates the National Guard to help during a flood.
🔵 Federal Activation (Title 10)
Authority: President of the United States
Use: National defense, overseas deployment, wartime missions
Command: The Guard comes under federal control (Department of Defense)
Funding: Federally funded
âś… Example: The President federalizes Guard troops for deployment to a foreign conflict.

🔶 Dual-Status Command
In certain complex situations (like major national emergencies), a dual-status commander may be appointed to command both state and federal troops simultaneously. This helps coordinate response while maintaining clear lines of authority.
Summary Table
| Status | Activated By | Command | Use Case |
|---|---|---|---|
| State Active Duty | Governor | State | Emergencies, civil unrest |
| Title 32 | Governor (approved by DoD) | State | Training, domestic ops with federal funding |
| Title 10 | President | Federal | National defense, overseas deployment |
Here’s an example of a major event where the National Guard was activated:
🌀 Hurricane Katrina (2005)
đź“Ť Location: Louisiana, Mississippi, Alabama
🗓️ Date: August–September 2005
📢 Activated by:
Governors (Louisiana, Mississippi, Alabama) – under State Active Duty and Title 32
Later Federalized by President George W. Bush – under Title 10
🔍 What Happened
Hurricane Katrina was one of the deadliest and costliest natural disasters in U.S. history. When the storm hit the Gulf Coast:
Governors activated thousands of National Guard troops to assist with evacuations, rescue operations, shelter setup, and recovery efforts.
The initial response was state-led, with each state’s National Guard under the governor’s command.
As the crisis worsened, with New Orleans experiencing catastrophic flooding and civil unrest, President Bush federalized elements of the Guard to streamline coordination with the active-duty military.
đź“Š Scale of Activation
Over 50,000 National Guard troops from all 50 states were eventually deployed.
They conducted:
Search and rescue
Law enforcement support
Medical aid
Infrastructure repair
Food and water distribution
⚖️ Legal and Command Issues
There was confusion and delay due to overlapping authorities between state and federal commands.
Posse Comitatus Act limited active-duty military’s ability to enforce domestic law, so Guard units under state control were crucial for law enforcement roles.
🧠Lessons Learned
Led to reforms in disaster response coordination, including:
Better dual-status command structures
Improved communication protocols between FEMA, the DoD, and state governments
