Bluff Great House is an Ancestral Puebloan great house and archeological site located in southeastern Utah, United States.
 The site lies near the north bank of the San Juan River, approximately 130 miles northwest of Chaco Culture National Historical Park.
 It contained between fifty and sixty rooms, with four kivas and a great kiva nearby.
 Two ancient road segments were found in the area, and several berms were leveled to create a terrace, which is rare in Chacoan sites.
 The great house was partially excavated from 1996 to 2004, and archeologists believe the site was constructed, in at least two stages, between 1075 and 1150 CE by Chacoans who interacted with the Puebloan residents of both Mesa Verde and Kayenta, Arizona.
 Bluff Great House was abandoned  1250 .
John Brown (May 9, 1800 – December 2, 1859) was an American abolitionist who believed and advocated that armed insurrection was the only way to overthrow the institution of slavery in the United States.
 Brown first gained attention when he led small groups of volunteers during the Bleeding Kansas crisis of 1856.
 Dissatisfied with the pacifism of the organized abolitionist movement, he said, "These men are all talk.
 What we need is action—action!"
 During the Kansas campaign, Brown commanded forces at the Battle of Black Jack and the Battle of Osawatomie.
 He and his supporters killed five supporters of slavery in the Pottawatomie massacre of May 1856 in response to the sacking of Lawrence by pro-slavery forces.
Philip H. Murray (1842 - February 17, 1917) was an abolitionist, journalist, phrenologist, and civil rights activist who spent most of his career in St. Louis, Missouri.
 He grew up in Reading, Pennsylvania where he participated in the abolitionist movement in that region.
 During the US Civil War he continued his work and served as a recruiting officer to help enlist blacks into the Union Army.
 After the war, he focused on journalism.
 In 1867, he established the first black newspaper in Kentucky, "The Colored Kentuckian".
 He later moved to St. Louis where he continued to work in journalism and as an advocate for black education and civil rights.
 He was also the president of the first Negro Press Association.
Hiram Wilson (September 25, 1803 – April 16, 1864) was an anti-slavery abolitionist who worked directly with escaped and former slaves in southwestern Ontario.
 He attempted to improve their living conditions and help them to be integrated into society by providing education and practical working skills.
 He established ten schools to educate free blacks in southwestern Ontario.
 Wilson worked extensively with Josiah Henson to establish the British-American Institute and the Dawn Settlement in 1841.
 Wilson was a delegate to the 1843 World Anti-Slavery Convention in London, England.
 Wilson eventually resigned from the British-American Institute and moved to St. Catharines, Ontario, where his home was the final terminal for the Underground Railroad.
Nouvelle artificial intelligence (AI) is an approach to artificial intelligence pioneered in the 1980s by Rodney Brooks, who was then part of MIT artificial intelligence laboratory.
 Nouvelle AI differs from classical AI by aiming to produce robots with intelligence levels similar to insects.
 Researchers believe that intelligence can emerge organically from simple behaviors as these intelligences interacted with the "real world," instead of using the constructed worlds which symbolic AIs typically needed to have programmed into them.
Uncle Tom's Cabin Historic Site is an open-air museum and African American history centre near Dresden, Ontario, Canada, that includes the home of Josiah Henson, a former slave, author, abolitionist, and minister, who, through his 1849 autobiography "The Life of Josiah Henson, Formerly a Slave, Now an Inhabitant of Canada, as Narrated by Himself", was the inspiration for Harriet Beecher Stowe's title character in her novel "Uncle Tom's Cabin".
 The 5 acre complex is part of the original 200 acre of land purchased in 1841 to establish the Dawn Settlement, a community for escaped slaves.
Abolitionism or abolitionist veganism is the animal rights based opposition to all animal use by humans.
 Abolitionism maintains that all sentient beings, humans or nonhumans, share a basic right: the right not to be treated as the property of others.
 Abolitionist vegans emphasise that animal products require treating animals as property or resources and that animal products are not necessary for human health in modern societies.
 Abolitionists believe that everyone who can live vegan is therefore morally obligated to be vegan.
Josiah Henson (June 15, 1789 – May 5, 1883) was an author, abolitionist, and minister.
 Born into slavery, in Port Tobacco, Charles County, Maryland, he escaped to Upper Canada (now Ontario) in 1830, and founded a settlement and laborer's school for other fugitive slaves at Dawn, near Dresden, in Kent County, Upper Canada, of British Canada.
 Henson's autobiography, "The Life of Josiah Henson, Formerly a Slave, Now an Inhabitant of Canada, as Narrated by Himself" (1849), is believed to have inspired the title character of Harriet Beecher Stowe's "Uncle Tom's Cabin" (1852).
 Following the success of Stowe's novel, Henson issued an expanded version of his memoir in 1858, "Truth Stranger Than Fiction.
 Father Henson's Story of His Own Life" (published Boston: John P. Jewett & Company, 1858).
 Interest in his life continued, and nearly two decades later, his life story was updated and published as "Uncle Tom's Story of His Life: An Autobiography of the Rev. Josiah Henson" (1876).
Philip Henson (December 28, 1827 - January 10, 1911) was a scout and spy for the Union Army during the American Civil War.
 Upon the election of U.S. Grant to the U.S. Presidency (1869–1877), Henson became the "first Special" Secret Service Agent of the United States of America, serving until Grant's death in 1885.
 During the course of his life and careers, Philip Henson would interact with such famous 19th century persons as abolitionist John Brown, Cherokee Chiefs John Ross a.k.a. Kooweskoowe and Stand Watie a.k.a. Degataga, Tennessee and Texas Governor Sam Houston, actor John Wilkes Booth, Confederate Postmaster General John Henninger Reagan, Confederate Secretary of State Judah Philip Benjamin, U.S. Congressman from Illinois Elihu Benjamin Washburne, Union General and Transcontinental Railroad executive Grenville Mellen Dodge, New York political boss William Marcy Tweed, Medal of Honor recipient First Lieutenant "Nineveh Shaw McKeen" (1837–1890), and the ancestors of 20th century Hollywood legend Cecil B. DeMille.
Frederick Douglass (born Frederick Augustus Washington Bailey;  February 1818  – February 20, 1895) was an African-American social reformer, abolitionist, orator, writer, and statesman.
 After escaping from slavery in Maryland, he became a national leader of the abolitionist movement in Massachusetts and New York, gaining note for his dazzling oratory and incisive antislavery writings.
 In his time, he was described by abolitionists as a living counter-example to slaveholders' arguments that slaves lacked the intellectual capacity to function as independent American citizens.
 Northerners at the time found it hard to believe that such a great orator had once been a slave.
