C Troop, 1st Squadron, 153rd Cavalry is a unit of the Florida Army National Guard, stationed in Tallahassee, Florida.
 The unit has one of the oldest continuous lineages in the Florida National Guard with history dating back to the first militia units formed in the town in 1836.
 In 1857, Captain John Pakhill, his brother Samuel M. Parkhill, and Theordore Brevard, Jr. formed a mounted company of "Leon Volunteers" to fight in the Third Seminole War, where John Parkhill was killed in action.
 John Parkhill's cousin, Captain George W. Parkhill and his brother, Richard C. Parkhill formed a new company called the "Governor's Guards" circa 1859-1860 which later changed its name to "Howell Guards" and fought with the Second Florida Infantry during the Civil War.
 After the war, the company reorgaznized as "Governor's Guards", a local militia company, under the command of Captain Alexander Moseley and have had a near-continuous lineage henceforth.
 The Governor's Guards served as an infantry unit for most of its existence, including in the Civil War, World War I, World War II, the Iraq War and the Global War on Terrorism.
 Today, Charlie Troop, is a dismounted infantry reconnaissance troop.
Zadock Pratt Jr. (October 30, 1790 – April 5, 1871) was a tanner, banker, soldier, and member of the United States House of Representatives.
 Pratt served in the New York militia from 1819–1826, and was Colonel of the 116th regiment from 1822 until his resignation from the militia on September 4, 1826.
William Henry Harman (February 17, 1828  – March 2, 1865) was a brigadier general in the Virginia militia and colonel in the Confederate States Army during the American Civil War (Civil War).
 Prior to the war, Harman had served as a second lieutenant in the 1st Virginia Infantry Regiment during the Mexican-American War, after which he had become a lawyer.
 He was commonwealth's attorney for Augusta County, Virginia from 1851 until the beginning of the Civil War, when he was appointed a brigadier general in the state militia.
Gabriel Gatwech Chan (better known by his nickname Gabriel Tang or Gabriel Tang Ginye; 1960–4 January 2017) was a rebel militia leader in South Sudan.
 General Tang led a southern border militia allied to the Khartoum government during Sudan's civil war.
 Most of his fighters are of the Nuer ethnic group.
 Members of the Sudanese armed forces loyal to Gen Tang in Malakal clashed with the Sudan People's Liberation Army (SPLA) in 2006, killing about 150 people, and in 2009 in breach of the peace deal.
 In April 2011, clashes between his militia and the SPLA in the state of Jonglei killed at least 57 according to government officials.
 Shortly thereafter, Tanginye surrendered to SPLA forces and had been under house arrest in Juba awaiting charges against him.
 During the South Sudanese Civil War, he allied with Lam Akol's militia, a Juba linked rebel group called the National Democratic Movement and became its chief of staff.
 In January 2017 he was killed in a clash with a group led by John Uliny from the main rival rebel group, the SPLM-IO.
 In these clashes in the Hamra area in the northern Upper Nile, 20 others were killed.
The Enrolled Missouri Militia was a state militia organization of Missouri in 1862 during the American Civil War.
 It was a part-time force whose primary purpose was to serve as garrison and infrastructure guards, both to augment the Unionist Missouri State Militia in defense versus raids and to free the Missouri State Militia for offensive operations versus Confederate guerrillas and recruiters.
The Arkansas Militia in Reconstruction was deeply involved in the ongoing civil disturbances which plagued the state until the late 1870s.
 In the immediate aftermath of the Civil War, the militia was first utilized by the white population to re-establish control over the newly freed black population.
 Radical Republicans seized control in 1867 and abolished existing state governments and militia organizations, and disenfranchised former Confederates.
 The new disenfranchised whites turned to the shadow Ku Klux Klan to attempt to maintain social order.
 The Re-constructionist government raised a new militia, primarily of black soldiers with white officers and utilized this new "Black Militia" to put down the rising power of the Ku Klux Klan.
 Armed conflicts between rival parties continued in several counties and the Militia was called to re-establish control in Pope and Scott Counties.
 The most severe conflict of this period occurred during the so-called Brooks–Baxter War with rival parties, with supporting militias, battling for control of the governorship.
 With the end of reconstruction one of the first acts of the new resurgent Democratic state legislature was to abolish the office of Adjutant General in retaliation for the use of the militia to enforce the rule of the Reconstruction government.
The units of the Arkansas Militia in the Civil War to which the current Arkansas National Guard has a connection include the Arkansas State Militia, Home Guard, and State Troop regiments raised by the State of Arkansas.
 Like most of the United States, Arkansas had an organized militia system before the American Civil War (1861–65).
 State law required military service of most male inhabitants of a certain age.
 Following the War with Mexico (1846–48) the Arkansas militia experienced a decline, but as sectional frictions between the north and south began to build in the late 1850s the militia experienced a revival.
 By 1860 the state's militia consisted of 62 regiments divided into eight brigades, which comprised an eastern division and a western division.
 New regiments were added as the militia organization developed.
 Additionally, many counties and cities raised uniformed volunteer companies, which drilled more often and were better equipped than the un-uniformed militia.
 These volunteer companies were instrumental in the seizure of federal installations at Little Rock and Fort Smith, beginning in February 1861.
The Baltimore riot of 1861 (also called the "Pratt Street Riots" and the "Pratt Street Massacre") was a civil conflict on Friday, April 19, 1861, on Pratt Street, (beginning at the President Street Station and President Street and continuing ending on Howard Street at the Camden Street Station) in Baltimore, Maryland, between antiwar "Copperheads" Democrats (the largest party in Maryland), as well as Southern / Confederate sympathizers, and members of the primarily Massachusetts and some Pennsylvania state militia regiments en route to the national capital at Washington called up for Federal service.
 It produced the first deaths by hostile action in the American Civil War and is nicknamed the "First Bloodshed of the Civil War".
Pratt Rock, also known as Pratt's Rock, is a rockface or other landform that includes a series of stone carvings in Prattsville, New York depicting the life of Zadock Pratt.
 Pratt was supposed to be buried in a tomb carved into the stone, but work was stopped after only a small recessed chamber was created because water leaked through the rock overhead, and excavating the stone was providing to be too difficult.
 The rock was originally a monument for Pratt's son, George W. Pratt, who was killed in the Civil War.
 It is considered the first memorial for the Civil War.
Albert Cresswell Garlington (June 9, 1822  – March 27, 1885) was a brigadier general in the South Carolina Militia, who served along with the Confederate States Army in South Carolina at various times during the American Civil War (Civil War).
 He was initially responsible for coastal defenses and militia in South Carolina, and then for training state troops.
 He briefly served as a major of the Holcombe Legion, a South Carolina unit guarding the coast in South Carolina for the Confederate States Army.
 After he resigned his commission on May 21, 1862, he served as state adjutant general and inspector general.
 Garlington again served as a brigadier general of militia in the Carolinas Campaign of late 1864 and early 1865.
