Dammartin is historically important as the seat of a county of which the holders played a considerable part in French history. The earliest recorded count of Dammartin was a certain Hugh, who made himself master of the town in the 10th century; but his dynasty was replaced by another family in the 11th century. Reynald I (Renaud), count of Dammartin (d. 1227), who was one of the coalition crushed by King 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 county was reunited after the death of Philip Hurepel's son Alberic. The county passed, through heiresses, to the houses of Fayel and Nanteuil, and in the 15th century was acquired by Antoine de Chabannes (d. 1488), one of the favorites of King Charles VII, by his marriage with Marguerite, heiress of Reynald V of Nanteuil-Aci and Marie of Dammartin. This Antoine de Chabannes, count of Dammartin in right of his wife, 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 Dammartin was founded by him in 1480, 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 county to Philippe de Boulainvilliers, by whose heirs it was sold in 1554 to the dukes of Montmorency. In 1632 the county was confiscated by Louis XIII and bestowed on the princes of Conde.
Inhabitants of Dammartin-en-Goële are called Dammartinois.
