Colonial history of the East Regiment (present-day
Massachusetts Army National Guard) in
Salem,
Massachusetts Bay Colony, Spring 1637, as imagined by artist
Don Troiani in the 1980s On December 13, 1636, the General Court of the
Massachusetts Bay Colony ordered that the Colony's scattered militia companies be organized into North, South and East Regiments—with the goal of increasing accountability to the colonial government and responsiveness during conflicts with indigenous
Pequot Indians. Under this act, white males between the ages of 16 and 60 were obligated to possess arms and to take part in the defense of their communities by serving in nightly guard details and participating in weekly drills. The modern-day
101st Field Artillery Regiment,
182nd Infantry Regiment,
101st Engineer Battalion and
181st Infantry Regiment of the
Massachusetts Army National Guard are directly descended from the original colonial regiments formed in 1636. The Massachusetts militia units were mobilized either during or shortly after the above battles and used to form, along with units from Rhode Island, Connecticut and New Hampshire, the
Army of Observation during the
Siege of Boston. On July 3, 1775, General
George Washington, under the authority of the
Continental Congress, assumed command of the Army of Observation and the new organization became the
Continental Army from which the
United States Army traces its origins. Throughout the war, militia units were mobilized when British forces entered their geographic areas and participated in most of the battles fought during the war.
Nineteenth century The early United States distrusted
a standing army – in emulation of a long-standing British distrust – and kept the number of professional soldiers small. During the
Northwest Indian War, the majority of soldiers were provided by state militias. There are nineteen
Army National Guard units with campaign credit for the War of 1812. The Marquis de Lafayette
visited the U.S. in 1824–25. The 2nd Battalion, 11th New York Artillery, was one of many militia commands who turned out in welcome. This unit decided to adopt the title "National Guard," in honor of Lafayette's
French National Guard. The Battalion, later the 7th Regiment, was prominent in the line of march on the occasion of Lafayette's final passage through New York en route home to France. Taking note of the troops named for his old command, Lafayette alighted from his carriage, walked down the line, clasping each officer by the hand as he passed. Militia units provided 70% of the soldiers that fought in the
Mexican–American War, The majority of soldiers in the
Spanish–American War were from the National Guard. After the Great Railroad Strike of 1877, calls for military suppression of labor strikes grew louder, and National Guard units proliferated. In many states, large and elaborate armories, often built to resemble medieval castles, were constructed to house militia units. Businessmen and business associations donated monies for the construction of armories and to supplement funds of the local National Guard units. National Guard officers also came from the middle and upper classes. National Guard troops were deployed to suppress strikers in some of the bloodiest and most significant conflicts of the late 19th and early 20th centuries, including the
Homestead Strike, the
Pullman Strike of 1894, and the
Colorado Labor Wars.
Twentieth century Throughout the 19th century the Regular U.S. Army was small, and the state militias provided the majority of the troops during the
Mexican–American War, the
American Civil War, and the
Spanish–American War. With the
Militia Act of 1903, the militia was more organized and the name "National Guard" recommended. In 1908, the prohibition on National Guard units serving overseas was dropped. This resulted in constitutional debates within the U.S. government surrounding the legality of the use of the National Guard overseas, culminating in 1912 when U.S. Attorney General
George W. Wickersham declared the 1908 amendment to be unconstitutional. The
National Defense Act of 1916 contained a provision whereby the president could discharge National Guard members from the militia and draft them into the Army in the event of a war, allowing for their use overseas. This resulted in former National Guard members being discharged from the Army entirely (also losing their status as state troops) when they left service, so the
1920 amendments to the act defined the National Guard's dual role as a state and federal reserve force; the "National Guard while in the service of the United States" as a component of the
Army of the United States could be ordered to active duty by the president, be deployed overseas if they so wished, and the Guardsmen would then revert to their status as state troops. The dual state and federal status proved confusing, so in 1933, the National Defense Act of 1916 was amended again. It finally severed the National Guard's traditional connection with the militia clause of the Constitution, providing for a new component called the "National Guard of the United States" that was to be a reserve component of the Army of the United States at all times. This is the beginning of the present legal basis of the National Guard. In World War I, National Guard soldiers made up 40 percent of the men in U.S. combat divisions in France. In World War II, the National Guard made up 18 divisions. One hundred forty thousand Guardsmen were mobilized during the
Korean War and over 63,000 for
Operation Desert Storm. They have also participated in U.S. peacekeeping operations in
Somalia, Haiti,
Saudi Arabia, Kuwait,
Bosnia, and
Kosovo and for natural disasters, strikes, riots and security for the
Olympic Games when they have been in the States. Following World War II, the National Guard aviation units that had previously been part of the
U.S. Army Air Corps and its successor organization, the
U.S. Army Air Forces, became the
Air National Guard (ANG), one of two reserve components of the newly established
United States Air Force.
Domestic affairs Within hours of the devastating
San Francisco earthquake and fire of April 1906, the
California National Guard maintained order, protected lives and property and distributed relief supplies. Its role was controversial and it was withdrawn after 40 days. Federal troops also were used. On September 24, 1957, President
Dwight D. Eisenhower federalized the entire Arkansas National Guard to ensure the safe entry of the
Little Rock Nine to
Little Rock Central High School the following day. Governor
Orval Faubus had previously used members of the guard to deny the students entry to the school. The New York National Guard were ordered by Governor
Nelson A. Rockefeller to respond to the
Rochester 1964 race riot in July of that year. The
California Army National Guard were mobilized by the governor of California
Edmund Gerald Brown Sr. during the
Watts Riots, in August 1965, to provide security and help restore order. Elements of the
Ohio Army National Guard were ordered to
Kent State University by Ohio's governor
Jim Rhodes to quell anti-
Vietnam War protests, culminating in their
shooting into a crowd of students on May 4, 1970, killing four and injuring nine. The massacre was followed by the
Student strike of 1970. During the Vietnam War, service in the National Guard was highly sought after, as an enlistment in the Guard generally prevented a person from being sent to combat; only a handful of Guard units were ever deployed to Vietnam. In 1968, the National Guard had only 1.26% black soldiers. During the Vietnam War, Secretary of Defense Robert McNamara created the
Selective Reserve Force (SRF) in October 1965. Since funding was not available to train and equip the entire National Guard adequately, the SRF would be a core group of 150,000 National Guardsmen available and ready for immediate overseas deployment if needed. SRF units were supposed to be authorized at 100% strength, receive priority training funds and modern equipment, and have more training and do 58 hours of drills of four hours each a year rather than the standard 48 hours of drills. The 2nd Battalion 138th Field Artillery of the
Kentucky Army National Guard was ordered to service in
Vietnam in late 1968. The unit served in support of the regular
101st Airborne Division. The Battalion's C Battery lost nine men killed and thirty-two wounded when North Vietnamese troops overran Fire Base Tomahawk on June 19, 1969. During the early 1980s, the governors of California and Maine refused to allow deployment of their states' National Guard units to Central America. In 1986, Congress passed the Montgomery Amendment, which prohibited state governors from withholding their consent. In 1990, the Supreme Court ruled against the governor of Minnesota, who had sued over the deployment of the state's National Guard units to Central America. During the
1992 Los Angeles Riots, when portions of south central Los Angeles erupted in chaos, overwhelming the
Los Angeles Police Department's ability to contain the violence, the
California Army National Guard and selected units of the
California Air National Guard were mobilized to help restore order. The National Guard were attributed with five shootings of people suspected of violating the
curfew order placed on the city. , 4,000 National Guardsmen patrolled the city. During the 1993
Waco siege of the
Branch Davidians, elements of the
Alabama and
Texas Army National Guard were called in to assist the
ATF and the follow on effort by the
Federal Bureau of Investigation; the National Guard's involvement was limited to several specific areas; surveillance and reconnaissance, transport, maintenance and repairs, training and instruction, helicopters, unarmed tactical ground vehicles. The Army National Guard helicopters were also used to do photographic reconnaissance work. Training for ATF agents included such subjects as Close Quarters Combat, and combat medical instruction, and a mock up of the Mount Carmel complex was constructed at
Fort Hood, Texas for rehearsals. ATF also received several surplus helmets, flack vests, canteens, first aid dressings, empty magazines, and some night-vision equipment, in addition to MREs and diesel fuel. The FBI would request and receive the use of Bradley Armored Fighting Vehicles, and tank retrieval vehicles, as well as overflights by UH-1 and CH-47 helicopters.
Post Cold War reductions As a result of the Bottom Up Review and post-
Cold War force cutbacks, the Army National Guard maneuver force was reduced to eight divisions (from ten; the
26th Infantry and
50th Armored were consolidated in the northeastern states) and fifteen 'enhanced brigades,' which were supposed to be ready for combat operations, augmenting the active force, within 90 days.
2000s in Washington, D.C. National Guard units played a major role in providing security and assisting recovery efforts in the aftermath of the
September 11 attacks in 2001 and
Hurricane Katrina in 2005. In 2005, National Guard members and reservists were said to constitute a larger percentage of frontline fighting forces than in any war in U.S. history (about 43 percent in Iraq and 55 percent in Afghanistan). There were more than 183,366 National Guard members and reservists on active duty nationwide who left behind about 300,000 dependents, according to U.S. Defense Department statistics. In 2011, Army Chief of Staff Gen. George W. Casey Jr. stated that "Every Guard brigade has deployed to Iraq or Afghanistan, and over 300,000 Guardsmen have deployed in this war." In January and February 2007, National Guard troops from 8 states were activated to go help shovel snow, drop hay for starving cattle, deliver food and necessities to stranded people in their houses, and help control traffic and rescue stranded motorists in blizzards dropping feet of snow across the country. In the first quarter of 2007, United States Secretary of Defense
Robert M. Gates announced changes to the Guard deployment policy aimed at shorter and more predictable deployments for National Guard troops. "Gates said his goal is for Guard members to serve a one-year deployment no more than every five years... Gates is imposing a one-year limit to the length of deployment for National Guard Soldiers, effective immediately." Prior to this time, Guard troops deployed for a standard one-year deployment to
Iraq or
Afghanistan would serve for 18 or more months including training and transit time. During the transition to the new policy for all troops in the pipeline, deployed or soon to be deployed, some will face deployments faster than every five years. "The one-to-five year cycle does not include activations for state emergencies." Prior to the attacks against the United States on
September 11, 2001, the National Guard's general policy regarding mobilization was that Guardsmen would be required to serve no more than one year cumulative on active duty (with no more than six months overseas) for each five years of regular drill. Due to strains placed on active duty units following the attacks, the possible mobilization time was increased to 18 months (with no more than one year overseas). Additional strains placed on military units as a result of
the invasion of Iraq further increased the amount of time a Guardsman could be mobilized to 24 months. Current
Department of Defense policy is that no Guardsman is involuntarily activated for more than 24 months (cumulative) in one six-year enlistment period. Traditionally, most National Guard personnel serve "
One weekend a month, two weeks a year", although personnel in highly operational or high demand units serve far more frequently. Typical examples are pilots, navigators and aircrewmen in active flying assignments, primarily in the
Air National Guard, and to a lesser extent in the
Army National Guard, and special operations airmen and soldiers in both. A significant number also serve in a full-time capacity in roles such as Active Guard and Reserve (AGR) or Air Reserve Technician or Army Reserve Technician (ART). The "One weekend a month, two weeks a year" slogan has lost most of its relevance since the
Iraq War, when nearly 28% of total U.S. forces in Iraq and Afghanistan at the end of 2007 consisted of mobilized personnel of the National Guard and other Reserve components. In July 2012, the Army's top general stated his intention to increase the annual drill requirement from two weeks per year to
up to seven weeks per year. Prior to 2008, the functions of Agricultural Development Teams were within
Provincial Reconstruction Teams of the U.S. government. Today, ADTs consist of soldiers and airmen from the
Army National Guard and the
Air National Guard. Today, ADTs bring "an effective platform for enhanced dialogue, building confidence, sharing interests, and increasing cooperation amongst the disparate peoples and tribes of Afghanistan." These teams are not only affiliated with the military, they frequently work across agencies, for example with
USAID and the
Department of State. ADTs provide education and expertise on the ground, while also providing security and order that is traditionally affiliated with the military. These teams have been essential to the
counterinsurgency efforts in Afghanistan as a
public diplomacy tool to build relations with the local people in the tribes and provinces of the country. ADTs provide classroom instruction and teachings to Afghans about how to improve their farming practices during non-seasonal growing months, which allows the farmers to use skills in the winter to prepare for farming in the summer and fall. This enhances agricultural production and the Afghan economy as a whole. Agricultural education also improves lines of communication and builds trust between the people, the U.S. government, and the Host Nation. Additionally, through word of mouth in the provinces ideas are spread that inform others about these farming techniques, that may not have had direct interaction with the ADTs. The National Guard ADTs also introduce their U.S. civilian colleagues to the Afghan University personnel, which further strengthens relations and trust in the U.S. efforts in Afghanistan. ADTs also enhance public diplomacy in Afghanistan by providing security to the local provinces they are working within. This tool has provided the teams with the civilian-military partnership that is needed to conduct public diplomacy and defeat the insurgents in Afghanistan. President
Barack Obama said that the U.S. will enhance agricultural development instead of big reconstruction projects to build Afghanistan's economy, to have an immediate impact on the Afghan people. Today, these projects include "...basic gardening practices, to large watershed and irrigation projects. There are also projects that teach bee keeping and livestock production: all of which will have a positive impact on unemployment, hunger, and the ability to sustain future generations. However, this was met with resistance from states governors and members of the National Guard. The act was eventually passed, but instead, the president's authority was expanded to mobilize the reserve components for domestic operations without the consent of the governor, only during a natural disaster, terrorist attack, epidemic or other public health emergency. The following year, that authority was repealed.
2020s In 2020, the National Guard was activated for 11,000,000 "man days" in support of natural disasters,
civil unrest, food distribution at food banks, and
COVID-19 testing and vaccination. This was the highest number of activation days since World War II. in Washington, D.C. during the
George Floyd riots of June 2020 In 2025, 2,000 soldiers of the
California National Guard were federalized by President
Donald Trump by a
presidential memorandum to respond to incidents of
violence and
civil disorder against
Immigration and Customs Enforcement (ICE) and other United States Government personnel who were performing Federal functions in
Los Angeles for 60 days. On August 11, Trump announced the deployment of National Guards to Washington D.C. An additional deployment of National Guard troops to Memphis, Tennessee was announced on September 15. Proposals for a Domestic Civil Disturbance Quick Reaction Force consisting of two units of 300 soldiers of the National Guard were reported by
The Washington Post in August 2025. The force would be used to suppress civil unrest at short notice. ==Relevant laws==
