Prior to the 1918 boundary reforms, the county of Aberdeen had been covered, nominally, by the four constituencies of East Aberdeenshire, West Aberdeenshire, Aberdeen North, and Aberdeen South, and the county of Kincardine had been covered, nominally, by the Kincardineshire constituency. This arrangement dated from 1885, however, and predated both the redefinition of counties as local government areas, under the Local Government (Scotland) Act 1889, and the creation of the city of Aberdeen in 1900. 1918 constituency boundaries took account of new local government boundaries.
