At this time the county of Delmenhorst formed part of the dominions of the counts of Oldenburg, but afterwards it was on several occasions separated from them to form an appanage for younger branches of the family, namely in 1262-1447, 1463-1547, and 1577-1617.
Sel ajal moodustas Delmenhorsti krahvkond osa Oldenburgi krahvide valdustest, kuid hiljem oli see neist mitu korda eraldatud apanaaži moodustamiseks perekonna noorematele harudele, nimeliselt aastatel 1262-447, 1463-547 ja 1577-617.
