Prince Gaston of Orléans, Count of Eu was a French prince of the House of Orléans and a career military officer. He is best known for his service as a senior commander in the Hispano-Moroccan War and for his prominent role in the Paraguayan War, where he commanded Allied forces during the final phase of the conflict. Born into the French royal family as the eldest son of Louis, Duke of Nemours and Princess Victoria of Saxe-Coburg and Gotha, Gaston later became a central figure in Brazilian imperial history through his marriage to Princess Isabel, daughter and heir of Pedro II of Brazil. As prince consort to the heiress presumptive, he played a significant role in the political, military, and dynastic affairs of the Empire of Brazil during its final decades.
