Input: Question: Who won the American Civil War? Passage 1:The novel provided the basis for a subsequent film version, produced in the Universum Film AG (Ufa) studios. The plot was written by Bobby E. Lüthge and Karl Aloys Schenzinger, the author of the novel. Produced by Karl Ritter, the film was supported by the Nazi leadership and produced for 320,000 reichsmarks under the aegis of Baldur von Schirach. The latter also wrote the lyrics for the Hitler Youth song "Unsere Fahne flattert uns voran", based on an existing melody by Hans-Otto Borgmann, who was also responsible for the music. The director was Hans Steinhoff. For the film, the novel's title was amended with the subtitle Ein Film vom Opfergeist der deutschen Jugend ("A film about the sacrificial spirit of German youth"). The film has a length of 95 minutes (2,605 metres) and was premiered on 11 September 1933 at the Ufa-Phoebus Palace, Munich, and on 19 September at the Ufa-Palast am Zoo, Berlin. It was one of three films about Nazi martyrs in 1933, the other two being SA-Mann Brand and Hans Westmar, and by January 1934 had been viewed by a million people.
 Passage 2:The Habeas Corpus Suspension, (1863), entitled An Act relating to Habeas Corpus, and regulating Judicial Proceedings in Certain Cases, was an Act of Congress that authorized the president of the United States to suspend the privilege of the writ of habeas corpus in response to the American Civil War and provided for the release of political prisoners. It began in the House of Representatives as an indemnity bill, introduced on December 5, 1862, releasing the president and his subordinates from any liability for having suspended habeas corpus without congressional approval. The Senate amended the House's bill, and the compromise reported out of the conference committee altered it to qualify the indemnity and to suspend habeas corpus on Congress's own authority. Abraham Lincoln signed the bill into law on March 3, 1863, and suspended habeas corpus under the authority it granted him six months later. The suspension was partially lifted with the issuance of Proclamation 148 by Andrew Johnson, and the Act became inoperative with the end of the Civil War. The exceptions to his Proclamation 148 were the States of Virginia, Kentucky, Tennessee, North Carolina, South Carolina, Georgia, Florida, Alabama, Mississippi, Louisiana, Arkansas, and Texas, the District of Columbia, and the Territories of New Mexico and Arizona.
 Passage 3:The George S. Houston Historic District is a historic district in Athens, Alabama. The district lies to the west and north of the public square, and features homes of some of the town's most prominent residents. Development began in the district soon after the town was founded in 1818; there are five homes remaining from the antebellum period. The district saw moderate growth between the Civil War and the early 1900s, most of which are Queen Anne and Victorian styles. The majority of houses in the district were constructed between 1908 and 1939. As the need for housing in the town grew, larger antebellum lots were subdivided and new construction was added. Larger houses tended to be American Foursquares, while middle-class houses were bungalows and cottages, some with Tudor Revival and Colonial Revival details. The district is entirely residential, with the exception of the First Methodist Church, built in 1925 in Neoclassical style; 400 North Jefferson was built in 1935 as a hospital, but later converted to apartments. Other notable properties in the district include the George S. Houston House, which was converted into a public library. The district was listed on the National Register of Historic Places in 1989.
