The area around the village was populated already during the Stone Age, which some weapon finds testify. Delliehausen was first mentioned in a Ludolf V. von Dassel certificate gifting his estate in Deligehusen to the monastery Steina in the year 1293. An earlier mentioning of a village Daillanhus in the Vita Meinwerci can not be attached for sure to today's Delliehausen. Delliehausen is part of the seigniory monastery Steina, but was passed over to the dukes of Braunschweig in 1366, who built here a stately barbican with more extensive property. Delliehausen was otherwise a woodsmen and charburner village mostly, testified by a still working museum charcoal kiln. The barbican was dissolved around 1800. From 1885 to 1911 brown coal was opencast mined up to 50 metres down near the village. Today's hill lake originated from this opencast mining. The independent community is now part of the then newly formed larger community Uslar since the 1st of March 1974.

The settlement Haje was founded in the 18th-century only.
