The Birth of a Nation (originally called The Clansman) is a 1915 American silent epic drama film directed and co-produced by D. W. Griffith and starring Lillian Gish. The screenplay is adapted from the novel and play The Clansman, both by Thomas Dixon Jr., as well as Dixon's novel The Leopard's Spots. Griffith co-wrote the screenplay with Frank E. Woods, and co-produced the film with Harry Aitken. It was released on February 8, 1915.

In 1912, Thomas Dixon Jr. decided that he wanted to turn his popular 1905 novel and play The Clansman into a film, and began visiting various studios to see if they were interested. In late 1913, Dixon met the film producer Harry Aitken, who was interested in making a film out of The Clansman, and through Aitken, Dixon met Griffith. Griffith was the son of a Confederate officer and, like Dixon, viewed Reconstruction negatively. Griffith believed that a passage from The Clansman where Klansmen ride "to the rescue of persecuted white Southerners" could be adapted into a great cinematic sequence. Griffith began production in July 1914 and was finished by October 1914. The Birth of a Nation began filming in 1914 and pioneered such camera techniques as close-ups, fade-outs, and a carefully staged battle sequence with hundreds of extras made to look like thousands. It also contained many new artistic techniques, such as color tinting for dramatic purposes, building up the plot to an exciting climax, dramatizing history alongside fiction, and featuring its own musical score written for an orchestra. The film was based on Dixon's novels The Clansman and The Leopard's Spots. It was originally to have been shot in Kinemacolor, but D. W. Griffith took over the Hollywood studio of Kinemacolor and its plans to film Dixon's novel. Griffith, whose father served as a colonel in the Confederate States Army, agreed to pay Thomas Dixon $10,000 (equivalent to $244,319 today) for the rights to his play The Clansman. Since he ran out of money and could afford only $2,500 of the original option, Griffith offered Dixon 25 percent interest in the picture. Dixon reluctantly agreed, and the unprecedented success of the film made him rich. Dixon's proceeds were the largest sum any author had received for a motion picture story and amounted to several million dollars. The American historian John Hope Franklin suggested that many aspects of the script for The Birth of a Nation appeared to reflect Dixon's concerns more than Griffith's, as Dixon had an obsession in his novels of describing in loving detail the lynchings of black men, which did not reflect Griffith's interests. Griffith's budget started at US$40,000 (equivalent to $970,000 today) but rose to over $100,000 (the equivalent of $2,420,000 in constant dollars). West Point engineers provided technical advice on the American Civil War battle scenes, providing Griffith with the artillery used in the film. Some scenes from the movie were filmed on the porches and lawns of Homewood Plantation in Natchez, Mississippi. The film premiered on February 8, 1915, at Clune's Auditorium in downtown Los Angeles. At its premiere the film was entitled The Clansman; the title was later changed to The Birth of a Nation to reflect Griffith's belief that the United States emerged from the American Civil War and Reconstruction as a unified nation.
