During what historical event was the National Guard formed?

The National Guard was formed as a response to the need for local defense and military organization during a time when colonies were facing threats from both external and internal forces. This context aligns with the concept of Colonial Defense, which reflects how early American settlers organized militias to protect their communities. Militia groups were composed of local citizens who trained to defend their settlements and assist in state security—often stepping in during conflicts like the French and Indian War and preceding the American Revolution.

The concept of Colonial Defense pre-dates an organized National Guard but set the stage for its later official establishment. This foundation was crucial as it emphasized local community involvement in defense and security, a principle that continues to influence the structure and purpose of the National Guard today.
