Band of Brothers is a 2001 American[1] war drama miniseries based on historian Stephen E. Ambrose’s 1992 non-fiction book of the same name.[2] It was created by Steven Spielberg and Tom Hanks, who also served as executive producers, and who had collaborated on the 1998 World War II film Saving Private Ryan.[3] Episodes first aired on HBO starting on September 9, 2001. Critically acclaimed, the series won the Emmy and Golden Globe awards for best miniseries.

The series dramatizes the history of “Easy” Company, 2nd Battalion, 506th Parachute Infantry Regiment of the 101st Airborne Division. It begins during Easy Company’s paratrooper training and follows its participation in the Western Front of World War II. The events are based on Ambrose’s research and recorded interviews with Easy Company veterans. The series took some literary license, adapting history for dramatic effect and series structure.[4][5] The characters portrayed are based on members of Easy Company. Each episode begins with excerpts from interviews with some of the survivors, who are identified by name only at the end of the finale.

The title of the book and series comes from the St. Crispin’s Day speech in William Shakespeare’s play Henry V, delivered by King Henry before the Battle of Agincourt. Ambrose quotes a passage from the speech on his book’s first page; this passage is recited by Carwood Lipton in the series finale.
