County Antrim is one of six counties that form Northern Ireland, situated in the north-east of the island of Ireland. Adjoined to the north-east shore of Lough Neagh, the county covers an area of 3,046 square kilometres (1,176 sq mi). It is one of six traditional counties of Northern Ireland and is within the historic province of Ulster.
Antrim is divided into sixteen baronies. Lower Antrim, part of Lower Clandeboye, was settled by the sept O'Flynn/O'Lynn. Upper Antrim, part of Lower Clandeboye, was the home of the O'Keevans. Belfast was part of Lower Clandeboye and was held by the O'Neill-Clannaboys. Lower Belfast, Upper Belfast, and Carrickfergus were also part of Lower Clandeboye. Cary was part of the Glynnes; ruled originally by the O'Quinn sept, the MacDonnell galloglasses from Scotland took power here in the late Middle Ages and some of the O'Haras also migrated from Connaught.
