DAMMARTIN, a small town of France, in the department of Seine et Marne, 22 m. N.E. of Paris. Situated on a hill form ing part of the plateau of la Goele, it is known as Dammartin-en Gale to distinguish it from Dammartin-sous-Tigeaux, a small , commune in the same department. Hugh, the earliest recorded count of Dammartin, made himself master of the town in the loth century. His dynasty was replaced by another family in the iith century. Reynald I. (Renaud), count of Dammartin (d. 1227), who was one of the coalition crushed by Philip Augustus at the battle of Bouvines (1214), left two co-heiresses, of whom the elder, Maud (Matilda or Mahaut), married Philip Hurepel, son of Philip Augustus, and the second, Alix, married Jean de Trie, in whose line the countship was reunited after the death of Philip Hurepel's son Alberic. In the sth century the countship was acquired by Antoine de Chabannes (d. 1488) by his marriage with Marguerite, heiress of Reynald V. of Nanteuil-Aci and Marie of Dammartin. Antoine de Chabannes fought under the standard of Joan of Arc, became a leader of the Ecorcheurs, took part in the war of the public weal against Louis XI., and then fought for him against the Burgundians. The collegiate church at Dam martin was founded by him in 148o, and his tomb and effigy are in the chancel. His son, Jean de Chabannes, left three heiresses, of whom the second left a daughter who brought the countship to Philippe de Boulainvilliers, by whose heirs it was sold in 1554 to the dukes of Montmorency. In 1632 the countship was confiscated by Louis XIII. and bestowed on the princes of Conde.
