The UP is an amalgamation of Muzorewa's former party, United African National Council, and a Matebeleland and Masvingo-based faction of the Forum Party which had been formed in 1993.  The UP also received members from the Zimbabwe Unity Movement, the party founded by former ZANU PF secretary general Edgar Tekere in 1989. Simeon "Sima" Pandurović (; 14 April 1883 – 27 August 1960) was a Serbian poet, part of the Symbolist movement in European poetry at the time.  He was one of the founders of the "Moderna" movement in Serbian poetry.  Young Pandurović was educated at Belgrade's Grande École (Velika škola), and after a brief experience at teaching determined to devote himself to literature, writing poetry and criticism for literary magazines, particularly "Misao," which he founded shortly after the war.  At the beginning of the 20th century, he joined "the poets of pessimism" – Milan Rakić and Vladislav Petković Dis – then under the influences of Charles Baudelaire and Edgar Allan Poe. Tangerine Dream is a German electronic music band founded in 1967 by Edgar Froese.  The group has seen many personnel changes over the years, with Froese being the only continuous member until his death in January 2015.  The best known line-up of the group was its mid-70s trio of Froese, Christopher Franke, and Peter Baumann.  In the late 1970s, Johannes Schmoelling replaced Baumann.  Since Froese's death the group has been under the leadership of Thorsten Quaeschning, Edgar's chosen successor who joined the group in 2005. Sahaja Yoga is a new religious movement founded in 1970 by Nirmala Srivastava (1923-2011), more widely known as Shri Mataji Nirmala Devi or as "Mother" by her followers, who are called Sahaja yogis.  Sahaja Yoga is not only the name of the movement, but also the meditation technique the movement teaches and the state of awareness that is said to be achieved by the technique.  According to the movement, this state is the state of self-realization produced by kundalini awakening and is accompanied by the experience of thoughtless awareness or mental silence.  The movement teaches the belief that self-realization through kundalini awakening is a transformation which can be experienced on the central nervous system and results in a more "moral, united, integrated and balanced" personality.

Overton Farm is a historic farm house near Hodges, Alabama.  The farmstead was founded by Abner Overton, a traveling tobacco merchant from Raleigh, North Carolina.  Overton purchased 160 acres (65 ha) in a bend of Bear Creek in 1817.  Overton constructed a one-room log cabin in 1819, and gradually added to the house until it consisted of five rooms.  Only two rooms of the house remain, separated by a dogtrot breezeway.  The original west room originally had a stone chimney in the gable end, but it is no longer standing.  The farm was operated by the Overton family until 1946 and was purchased by the Tennessee Valley Authority in 1969 as part of the land affected by the construction of Bear Creek Dam.  The farm was restored by the Northwest Alabama State Junior College in the 1970s and used as an educational center until 2013.  The house was listed on the National Register of Historic Places in 1973.

Stallman later established the Free Software Foundation in 1985 to support the movement. The Temperance movement in the United Kingdom originated as a mass movement in the 19th century.  Before this, though there were diatribes published against drunkenness and excess, total abstinence from alcohol was very rarely advocated or practised.  The earliest temperance societies, inspired by the Belfast professor of theology, and Presbyterian Church of Ireland minister John Edgar, who poured his stock of whiskey out of his window in 1829, concentrated their efforts on spirits rather than wine and beer.  Joseph Livesey was another British temperance advocate who financed his philanthropic work with the profits attained from cheese production, following an introduction to the food product by a doctor he had consulted with regards to a serious ailment in 1816.  The term "teetotal" is derived from a speech by Richard (Dickie) Turner, a follower of Livesey, in Preston in 1833.  Livesey opened the first temperance hotel in 1833 and the next year founded the first temperance magazine, "The Preston Temperance Advocate" (1834–37).  The British Association for the Promotion of Temperance was established by 1835. The American Indian Movement (AIM) is an American Indian advocacy group in the United States, founded in July 1968 in Minneapolis, Minnesota.  AIM was initially formed to address American Indian sovereignty, treaty issues, spirituality, and leadership, while simultaneously addressing incidents of police harassment and racism against Native Americans forced to move away from reservations and tribal culture by the 1950s-era enforcement of the U.S. federal government-enforced Indian Termination Policies originally created in the 1930s.  "As independent citizens and taxpayers, without good education or experience, most 'terminated' Indians were reduced within a few years to widespread illness and utter poverty, whether or not they were relocated to cities," from the reservations.  The various specific issues concerning Native American urban communities like the one in Minneapolis (disparagingly labeled "red ghettos") include unusually high unemployment levels, overt and covert racism, police harassment and neglect, epidemic drug abuse (mainly alcoholism), crushing poverty, domestic violence and substandard housing.  AIM's paramount objective is to create "real economic independence for the Indians." Raymond Edgar "Ray" Dodge (August 4, 1900 – March 28, 1985) was an American middle-distance runner.
