Context paragraphs:
Uncle Tom's Bungalow: Uncle Tom's Bungalow is an American "Merrie Melodies" animated cartoon directed by Tex Avery, and released to theatres on June 5, 1937 by Warner Bros. The short cartoon is a parody of the 1852 novel "Uncle Tom's Cabin" and of the “plantation melodrama” genre of the 1930s.  It contains many stereotypical portrayals of black characters.  The cartoon plays off Harriet Beecher Stowe's novel in that it portrays Uncle Tom as an old man, and wooden shacks and cotton fields pervade the scenery.  Director Tex Avery adds his own sense of humor and “trickster” animation, giving the classic theme a modern, humorous twist.

Uncle Tom's Cabaña: Uncle Tom's Cabaña is a 1947 American animated short film directed by Tex Avery.  The short is a parody of "Uncle Tom's Cabin", and is Avery's second parody of the novel, the first being "Uncle Tom's Bungalow" in 1937 while at Warner Bros.  Cartoons.

Uncle Tom syndrome: Uncle Tom syndrome is a concept in psychology.  It refers to a coping skill where individuals use passivity and submissiveness when confronted with a threat, leading to subservient behaviour and appeasement, while concealing their true thoughts and feelings.  The term "Uncle Tom" comes from the title character of Harriet Beecher Stowe's novel "Uncle Tom's Cabin", where the African American slave Tom is beaten to death by a cruel white master for refusing to betray the whereabouts of two other slaves.

Uncle Tom's Children: Uncle Tom's Children is a collection of novellas and the first book published by African-American author Richard Wright, who went on to write "Native Son" (1940), "Black Boy" (1945), and "The Outsider" (1953).  When it was first published in 1938, "Uncle Tom's Children" included only four novellas: "Big Boy Leaves Home," "Down by the Riverside," "Long Black Song," and "Fire and Cloud."  "The Ethics of Living Jim Crow" and "Bright and Morning Star," which are now the first and final pieces, respectively, were added when the book was republished in 1940.  The book's title is derived from Harriet Beecher Stowe's "Uncle Tom's Cabin," an anti-slavery novel published in 1852.

Film adaptations of Uncle Tom's Cabin: A number of film adaptations of "Uncle Tom's Cabin" have been made over the years.  Most of these movies were created during the silent film era (with "Uncle Tom's Cabin" being the most-filmed story of that time period).  Since the 1930s, Hollywood studios have considered the story too controversial for another adaptation (although one foreign film and a made-for-TV movie have been created).  Characters, themes and plot elements from "Uncle Tom's Cabin" have also influenced a large number of other movies, including "The Birth of a Nation" (1915), while also inspiring numerous animated cartoons.

Uncle Tom: Uncle Tom is the title character of Harriet Beecher Stowe's 1852 novel, "Uncle Tom's Cabin".  The term "Uncle Tom" is also used as a derogatory epithet for an excessively subservient person, particularly when that person is aware of their own lower-class status based on race.  The use of the epithet is the result of later works derived from the original novel.

Tom show: Tom show is a general term for any play or musical based (often only loosely) on the 1852 novel "Uncle Tom's Cabin" by Harriet Beecher Stowe.  The novel attempts to depict the harsh reality of slavery.  Due to the weak copyright laws at the time, a number of unauthorized plays based on the novel were staged for decades, many of them mocking the novel's strong characters and social message, and leading to the pejorative term "Uncle Tom".

Uncle Tom's Uncle: Uncle Tom's Uncle is a 1926 American short silent comedy film directed by Robert F. McGowan.  It was the 50th "Our Gang" short subject released.  The title is a play on the 1852 novel "Uncle Tom's Cabin".

Uncle Tom's Cabin (1910 Thanhouser film): Uncle Tom's Cabin is a 1910 American silent short drama produced by the Thanhouser Company.  The film was adapted by from the 1852 novel "Uncle Tom's Cabin" by Harriet Beecher Stowe.  The plot of the Thanhouser production streamlined the actual story to portray the film over the course of a single reel.  The film was released on July 26, 1910, on the same day that Vitagraph released the first reel of their own three reel version of "Uncle Tom's Cabin".  This prompted the Thanhouser Company to advertise against the Vitagraph film by referring to the other as being overly drawn out.  The film garnered mixed, but mostly positive reception in trade publications.  The film is presumed lost.

Dred: A Tale of the Great Dismal Swamp: Dred: A Tale of the Great Dismal Swamp is the second popular novel from American author Harriet Beecher Stowe.  It was first published in two volumes by Phillips, Sampson and Company in 1856.  Although it enjoyed better initial sales than her previous, and more famous, novel "Uncle Tom's Cabin", it was ultimately less popular.  "Dred" was of a more documentary nature than "Uncle Tom's Cabin" and thus lacked a character like Uncle Tom to evoke strong emotion from readers.
