(NewsUSA) – Ulysses S. Grant may be one of the most complex and underappreciated generals and presidents in United States history, but he gets his due at last in a six-hour miniseries, "Grant," that premieres on HISTORY over Memorial Day weekend.The three-part series is executive produced by Pulitzer Prize-winning writer Ron Chernow, author of the 2017 biography, "Grant," along with Appian Way’s Jennifer Davisson and Leonardo DiCaprio, and produced by RadicalMedia in association with global content leader Lionsgate. The first episode airs on Memorial Day, Monday, May 25, and continues over the next two nights at 9:00 p.m. ET/PT."Ulysses S. Grant is one of our most brilliant, yet misunderstood presidents and HISTORY is committed to telling the compelling stories, like his, of those who have shaped our great nation," says Eli Lehrer, executive vice president and general manager for HISTORY."This is an important part of American history that deserves to be told and we look forward to delivering our latest premium core history documentary series to our audience," he adds.Today, Grant is unfamiliar and misunderstood by many people, despite his worldwide fame at the time of his death in 1885. The three-night miniseries event combines dramatic scenes, expert commentary, and archival images to reveal Grant’s true legacy, which involves a rise from humble beginnings through the highest ranks of the military, and finally to the presidency.While serving as president from 1869-1877, he held the United States together during the challenges of reconstruction after the devastation of the Civil War.Many people may be unaware that Grant’s initiatives while in office include protecting the right to vote for the four-million formerly enslaved people freed at the end of the war despite violence and widespread resistance.In addition, "Grant" features on-camera interviews with "Grant" biographer Ron Chernow, as well as David Petraeus, retired United States Army General and former Central Intelligence Agency director; Ta-Nehisi Coates, acclaimed writer and journalist, and Elizabeth Samet, professor of English at West Point.Visit history.com for more information about the series and other premium, fact-based storytelling and entertainment.Also, follow @history on Instagram, Twitter, Facebook, and YouTube.
