The 2014 Bundy standoff was an armed confrontation between supporters of cattle rancher Cliven Bundy and law enforcement following a 21-year legal dispute in which the United States Bureau of Land Management (BLM) had obtained court orders directing Bundy to pay over $1 million in withheld grazing fees for Bundy's use of federally owned land adjacent to Bundy's ranch in southeastern Nevada.
Cliven D. Bundy (born April 29, 1946) is an American cattle rancher from Bunkerville, Nevada who is currently federally incarcerated and awaiting trial with bail denied for his role in the 2014 Bundy standoff.
 He vocally advocated a philosophy opposed to what he views as federal government overreach.
 He is known for having participated in the 2014 Bundy Standoff in Nevada, an armed standoff with federal and state law enforcement over defaulted grazing fees.
 Some viewed him as a hero for having led a movement of ranchers to encourage more ranchers to join him in defaulting on their grazing fees as per their federal grazing contracts.
 Some considered him to be dangerously provocative.
 He is the father of Ammon Bundy, who in 2016 also led another armed standoff against the government, the occupation of the Malheur National Wildlife Refuge in Oregon.
Isaiah Stillman (1793–15 April 1861) was an American Cavalry Major who led the Illinois militia in the first armed confrontation of the Black Hawk War against Black Hawk's Sauk Indian Band.

Leonis Adobe, built in 1844, is one of the oldest surviving private residences in Los Angeles County and one of the oldest surviving buildings in the San Fernando Valley.
 Located in what is now Calabasas, California, the adobe was occupied by the wealthy rancher Miguel Leonis (October 20, 1824 - September 20, 1889) until his death.
 Following Leonis' death, the property was the subject of a legal dispute between his common law wife Espiritu Chijulla (1836 - May 10, 1906), heirs, and a daughter born out of wedlock; the dispute lasted more than 15 years in the courts.
 In 1961, the adobe had fallen victim to vandalism, and its owner applied for a permit to raze the structure and erect a supermarket in its place.
 Preservationists succeeded in having the adobe declared a Historic-Cultural Landmark (the first structure in Los Angeles receiving the designation) in 1962.
Julio René Alvarado Ruano (2002?
-20 April 2016) was a fourteen-year-old Guatemalan male that was killed in the Belize–Guatemala adjacency zone during an armed confrontation between the Belize Defence Force, Belizean park rangers and Guatemalan farmers.
 The incident raised tensions between Belize and Guatemala, who have an ongoing border dispute since 1821.
 Belizean officials maintain that the Belize Defence Force acted in self-defence.
 However, the Guatemalan government claims the incident was a deliberate attack carried out by Belize's military.
 After the incident, the Organisation of American States agreed to investigate the death of Julio Alvarado at the request of both countries.
