Editing County Londonderry (section)

===19th century===
As a result of the [[Local Government (Ireland) Act 1898]], the city was detached from the county for administrative purposes, becoming a separate [[county borough]] from 1899.  The [[county town]] of County Londonderry, and seat of the [[Londonderry County Council]] until its abolition in 1973, was therefore moved to the town of [[Coleraine]].
