War and the Future (1917) is a work of war propaganda by H.G. Wells that was published in the North America under the title "Italy, France, and Britain at War" (the subtitle of the British original).
 Wells would have preferred the title "The War of Ideas", but his publisher over-ruled him.
 Except for the opening piece, its chapters were published as articles in the press.
 Though proclaiming early in the volume that "I avow myself an extreme Pacifist," Wells staunchly supported Britain's war against Germany "in the hope that so we and the world may be freed from the German will-to-power and all its humiliating and disgusting consequences henceforth for ever."
Kolberg is a 1945 German historical film directed by Veit Harlan.
 One of the last films of the Third Reich, it was intended as a Nazi propaganda piece to buoy the will of the German population to resist the Allies.
A Description of New England (in full: "A description of New England, or, Observations and discoveries in the north of America in the year of Our Lord 1614, with the success of six ships that went the next year, 1615") is a work written by John Smith and published in 1616 as a propaganda piece advertising the fertile land, abundant resources and general plenitude that was to be found in the New World.
Stevie is a 2002 film by documentarian Steve James, and Kartemquin Films.
Listen to Britain is a 1942 British propaganda short film by Humphrey Jennings and Stewart McAllister.
 The film was produced during World War II by the Crown Film Unit, an organisation within the British Government's Ministry of Information to support the Allied war effort.
 The film was nominated for the inaugural Academy Award for Documentary Feature in 1943, but lost against four other Allied propaganda films.
 It is noted for its nonlinear structure and its use of sound.
The Menglianggu Campaign (孟良崮战役) was a campaign fought between the nationalists and the communists during the Chinese Civil War in the post-World War II era and resulted in communist victory.
 The campaign was later used by the communists as a specific battle example in their military science and history, as well as a propaganda piece.
 The battle mainly took place in Menglianggu of Linyi region in Shandong Province.
Nazism created an elaborate system of propaganda, which made use of the new technologies of the 20th century, including cinema.
 Nazism courted the masses by the means of slogans that were aimed directly at the instincts and emotions of the people.
 The Nazis valued film as a propaganda instrument of enormous power.
 The interest that Adolf Hitler and his propaganda minister Joseph Goebbels took in film was not only the result of a personal fascination.
 The use of film for propaganda had been planned by the National Socialist German Workers Party as early as 1930, when the party first established a film department.
The position of Nazi propaganda towards the United Kingdom and its inhabitants changed over time.
 Prior to 1938, while Hitler tried to court Britain into an alliance, his propaganda praised the British as proficient Aryan imperialists.
 Later, as the Nazis realized that they would have to fight the United Kingdom, their propaganda vilified the British as oppressive, German-hating plutocrats.
 During the war, it accused "perfidious Albion" of war crimes, and sought especially to drive a wedge between Britain and France.
Under the Southern Cross (Italian:Sotto la croce del sud) is a 1938 Italian drama film directed by Guido Brignone and starring Antonio Centa, Doris Duranti and Enrico Glori.
 The film is set in Italian-occupied Abyssinia following the recent Italian victory there.
 It was one of a sequence of eight films set in Italy's African Empire during the Fascist era that were released between 1936 and 1939.
 The film is a propaganda piece designed to support Fascist policy on empire and concerns about inter-racial romances.
