Early Christian period In the 5th to 7th centuries (the beginning of the Early Christian period), Glenarm lay within the territory of the kingdom of
Dal Riada. This covered coastal County Antrim from Glenarm to
Bushmills. The inland boundary was formed by the watershed along the top of the Antrim hills. The coast of County Antrim south of Glenarm and west of Bushmills, as well as the lands south of the
River Bush lay within the territories of another group of tribes called the Dal nAraide (pronounced Dalnary). A branch of the Dal nAraide, known as Latharna, seems to have occupied the coast from just south of Glenarm to
Carrickfergus and beyond. The area at one point came under threat from the
Vikings who founded their only settlement of note in Ulster at "Ulfrek's fjord", present-day Larne. According to
Snorri Sturluson, an Icelandic historian, Connor, King of Ireland, defeated the raiding
Orkney Vikings at "Ulfreksfjord" in 1018. The name Olderfleet is a corruption of "Ulfrek's fjord". A local man was charged with the killing but later acquitted. ==Local politics==
