Marquis de Mores
Antoine-Amédée-Marie-Vincent Manca Amat de Vallombrosa, Marquis de Morès et de Montemaggiore (June 14, 1858 – June 9, 1896), commonly known as the Marquis de Morès, was a famous duelist, frontier ranchman in the Badlands of Dakota Territory during the final years of the American Old West era, a railroad pioneer in Vietnam, and an anti-Semitic politician in his native France.
Born Antoine-Amédée-Marie-Vincent Manca Amat de Vallombrosa, he inherited the title Marquis de Morès et de Montemaggiore, but he was usually called Marquis de Morès.
De Morès began life as a soldier, graduating in 1879 from St. Cyr, the leading military academy of France. Among his classmates was Philippe Pétain, famous French general of World War I and the ill-fated future leader of the Vichy France government in World War II.
After St. Cyr, he entered Saumur, France's premier cavalry school, where he trained to be an officer. He was later sent to Algiers, helping to put down an uprising. It was while in Algiers that he had his first duel, starting his career as the most celebrated duelist of his day.
He resigned from the cavalry in 1882 and married Medora von Hoffman, sometimes called the Marquise. Soon thereafter, he would move to the North Dakota badlands to begin ranching, purchasing 44,500 acres (180 km2) for that purpose. He also opened a stagecoach business. He named his simple vernacular house in Medora, North Dakota, the "Chateau de Mores"; it is preserved as a historic house there.
