On Dec. 13, 1636, the Massachusetts Bay Colony created four militia regiments. This marked the birth of the Army National Guard.
Both Plymouth Colony (1620-1691) and Massachusetts Bay Colony (1628-1691) immediately had small, part-time militia units (train bands) for their defense against indigenous tribes . Both militias relied on the English system, traceable to the Assize of Arms (1181), the Statute of Winchester (1285) and the Instructions for General Musters (1572). Originally, each militia company consisted of all able-bodied men between 16 and 60 years, with some exceptions. Someone with military experience controlled each company. For example, Myles Standish took charge in Plymouth in 1620 and John Endecott in Massachusetts at Salem in 1629.
The First Militia Regiments
The colonies equipped the militias with weaponry that included firearms (fowling pieces, matchlocks and flintlocks), swords, pikes, and small cannon. Upper-body armor (corselets) offered the men some protection in combat. Originally, the Plymouth militia held formal training drills (musters) six times a year. By 1632 the required militias in newly organized towns could determine their own training days and select their officers subject to Plymouth approval.
In 1631 in Massachusetts Bay, the General Court required each town to raise a local militia. By 1634, it required training once a month under appointed officers. These companies comprised anywhere from 65 to 200 men. Sometimes, however, several towns had to contribute for a town to reach the minimum of 65 members. Local militias in both colonies came to rely on property taxes, tariffs, fines, and donations to finance expenses.
From 1631-36, the number of towns in Massachusetts Bay with their militia companies greatly expanded. Thus, the General Court decided to establish a new regimental structure on Dec. 13, 1636, initially under the overall command of the governor. This legislation created the North, South, and East Regiments. The North Regiment included local militias from Charlestown, Cambridge, Concord, Medford and Watertown; the South Regiment had companies from Boston, Dorchester, Hingham, Roxbury and Weymouth; and the East Regiment comprised militias from Ipswich, Newbury, Saugus and Salem. The first regimental muster occurred in 1637 (April?) in Salem. A colonel and lieutenant colonel commanded each regiment, accompanied by a paid mustermaster. Each regiment and local militia elected its officers. By July 1637 volunteer militiamen from Massachusetts and Connecticut were urgently needed against the Pequot tribe in Connecticut.
Meanwhile, Plymouth Colony did not establish a regiment until 1658 under a civilian Council of War. In 1691 the colonial governments of Massachusetts Bay and Plymouth merged, including their militias.
Militia Regiments Redesignated
The three Massachusetts Bay regiments were redesignated on Sept. 7, 1643, after the General Court had created three counties the previous May. The North became the Middlesex Regiment, the South became the Suffolk Regiment and the East became the Essex Regiment. Members of these military units saw action against the Niantic and Narragansett tribes in 1645. They also fought in King’s Phillip’s War (1675-76), and the French and Indian War (1754-1763).

From the 17th through the 20th century, the three regiments experienced a succession of expansions, reorganizations and “call-ups” as a part of the U.S. Army. For example, the 2nd (Upper) Middlesex Regiment (formed in October 1680) fought at Lexington and Concord on April 19, 1775. On Jan. 1, 1776, previously reorganized regiments became redesignated as the 13th Massachusetts Regiment and the 6th and 23rd Continental Regiments. Realizing a need for more resources for national defense, Congress enacted the Militia Act of 1792. It gave the president the right to call up a militia “whenever the United States shall be invaded or be in imminent danger of invasion.”
The phrase “national guard,” as a synonym for a state militia, appeared in 1824 when the Marquis de Lafayette visited the U.S. By 1878 further recognition came with the creation of the National Guard Association of the United States, a lobbying group. Finally, the National Defense Act of 1916 mandated that state militias be referred to as the “National Guard.” In 1933 an amendment to the National Defense Act stated that the National Guard was a reserve part of the U.S. Army.
Army National Guard
After almost four centuries of historical evolution, four components of the Massachusetts Army National Guard can trace their ancestry to the three original Massachusetts Bay militias.
Both the 181st and 182nd Infantry Regiments have descended from the North Regiment; the 181st Field Artillery Regiment from the South Regiment; and the 101st Engineer Battalion from the East Regiment.
