Paul Riant

Paul Edouard Didier Riant (7 August 1836, Paris – 17 December 1888, Château La Vorpillière in Massongex) was a French historian and scientific editor specializing in the Crusades.

He exercised a great activity of scientific editor of primary sources related to the Crusades and the Latin States of the East. He created and chaired the Société de l'Orient Latin, as well as its official journal, the Revue de l'Orient latin, which continued to publish new issues until 1911. As a historian, he made a significant contribution to the study of the Northern Crusades, particularly those in the Scandinavian region.

Biography
Paul Riant was the son of Didier-Nicolas Riant (1790–1864), municipal councillor of Paris and general councillor of the Seine, and Joséphine Anne Françoise Fayard de Bourdeille (1809–1881). Riant had two half-brothers, Charles and Théodore, born from his father's first marriage to Louise Mignon (1795–1833).

Riant studied at the Jesuit college of Vaugirard in the 15th Arrondissement of Paris. In 1859, he undertook a study trip to Denmark, Norway, Sweden and Finland, and a second trip in 1862. In 1865, he earned his doctorate in philosophy at La Sorbonne, presenting a thesis Expeditions and pilgrimages of the Scandinavians to the Holy Land during the Crusades.

On 8 March 1864, his well-regarded thesis led to Riant being conferred by pope Pius IX the title of Roman Count (comes Romanus). From that date, he referred himself Count Paul Riant. His heraldic arms are those of Jacques Riant, captain of a company of one hundred men of ordinances under Louis XII of France.

In 1875, Riant founded the Société de l'Orient Latin devoted to the discovery and publication of documents relating to the Crusades. He served as secretary-treasurer and played a central role in the conduct of its work. Riant financed almost exclusively the publication of the Archives de l'Orient Latin (AOL) (1881 and 1884) and the Revue de l'Orient Latin in twelve volumes (published from 1893 to 1911). He also supported the work of other researchers including the celebrated German historian Reinhold Röhricht. For Röhricht's work, Bibliotheca geographica Palaestinae, Riant provided numerous scarce documents and Röhricht dedicated this work to his memory when it was published in 1890, writing a commemorative article in the publication of the German Association for Palestine. Riant maintained relations with other authors of the school of German historians of the Crusade. For example, he was the author of a preface for the French translation of the 1883 edition of Heinrich Hagenmeyer's book on Pierre l'Ermite (Peter the Hermit).

In 1880, Riant was appointed member of the Académie des Inscriptions et Belles-Lettres. His role there dealt with issues of editing sources of the Crusades. On 8 September, 1868, he married Antoinette Cornuau d'Offémont (1845–1910), daughter of Baron d'Offémont. They had four children For health reasons, he spent part of his time at his Château de Vorpillière in Massongex, Switzerland. In 1882, he made it his permanent residence and died there six years later. He is buried in the Basilica of Saint Maurice.

The day after his death, his half-brother Theodore announced his death in a letter to the Académie des Inscriptions et Belles-Lettres. Throughout his life, Riant accumulated books and documents, having a monumental research library of more than 40,000 volumes.
